Php find parse error

Tips, tricks
and all of the stuff you should
know about BeTheme

Have you experienced exploring on WordPress site, then the following errors suddenly generated?

• parse error: syntax error, unexpected t_string wordpress,
• parse error syntax error unexpected end of file in wordpress,
• parse error: syntax error, unexpected t_function wordpress,
• parse error syntax error unexpected text t_string wordpress,
• parse error syntax error unexpected if t_if wordpress,
• wordpress parse error syntax error unexpected expecting or ‘;’

Having these syntax errors denies access to your website and brings a lot of inconveniences. The ‘parse error syntax error unexpected’ may intimidate you, and that’s completely understandable, but, debugging these errors is not too complicated. Fortunately, the error message indicates which part of the code causes the issue which makes it easier to fix. Thus, this article will enumerate ways to fix the syntax error and restore your website’s function.

What Is A Syntax Error?

By definition, syntax is an arrangement of elements such as words or a set of rules that determine the form of a structure. Thus, if there’s an element in your code that is not part of the syntax like an extra comma or if it’s missing an element that is supposed to be in the code like a missing bracket, the compiler will not be able to parse or process the file, and most likely to generate an error.

A syntax error appears when the ‘syntax’ of the rules are not followed correctly. It happens when the written code is not correct. For instance, there’s a missing semicolon, a misspelled word, or an additional bracket. Mistakes as simple as these can make the system lost in translation, but on the brighter side, these errors indicate where the issue comes from and how to solve it. For those who run multiple WordPress websites, you can monitor user activities in the WordPress dashboard to locate which user activity caused the error.

Also, keep in mind that WordPress websites may experience such issues without sending any notification to the user. To make yourself aware of any errors generated in your WordPress site, make sure that your WordPress error debug is always enabled.

The structure of a syntax error usually looks like this, “Parse error: syntax error, unexpected character in path/to/php-file.php on line number“; whereas undefined constant errors are structured like this, “Notice: Use of undefined constant constant string – assumed ‘constant string‘ in path/to/php-file.php on line number“. An example of an unexpected error is this, “Parse error: unexpected character in path/to/php-file.php on line number“.

The word ‘number’ refers to the line number written in nominal form like 25 or 1345 for instance. The ‘file’ tells you where the issue persists, the ‘line number’ hints you where the error is located, while the ‘character’ or the ‘constant string’ provides a clue on what to find exactly around the stated line number. Unexpected parse errors may also list a string instead of a character.

What Causes the PHP Parse or Syntax Errors In WordPress?

If a syntax error appears after installing a plugin or theme in the WordPress site, then the newly installed plugin or theme is most probably the cause of the error. The best way to solve it is to remove the recently added plugins by disabling them.

The WordPress site is also likely to generate an error after a code edit. A mistake as simple as a missing comma is enough to disrupt the function of a website. This renders the admin dashboard inaccessible, and to have an access to the site files, you may use a File Transfer Protocol or FTP client to make an edit.

How to Find Parse Error in WordPress?

The initial step to fixing a syntax error is to locate its source. This means finding out the particular file that contains the code with the error. Remember, when an error occurs, your website becomes inaccessible, and the worst thing that could happen would be not being able to locate the file in any way. So, in such difficult situations, a backup restore and re-installation of plugins or themes are the two possible options.

A parse error: syntax error, unexpected appears when the PHP interpreter detects a missing element. Most of the time, it is caused by a missing curly bracket “>”. To solve this, it will require you to scan the entire file to find the source of the error. This type of error is one of the hardest to locate because in some cases, the error is not exactly found along the line number indicated in the error message. One good way to avoid such issues is to run several tests to check the script during the programming phase.

Fixing the Syntax Error Using FTP

Fixing the syntax error involves code editing because it will require you to either delete or fix the syntax. A syntax error makes the entire WordPress site inaccessible, and in some cases, it locks the user out of the WordPress admin dashboard if the code or a snippet was pasted from a website into the WordPress site. This is often dreadful, especially for beginners in WordPress. In cases such as this, the best option would be to use an FTP program.

To access the latest edited file, you must install an FTP program and connect it to your WordPress site afterward. After connecting your website to the FTP program, go to the corrupted file or the theme file that needs to be edited. You may refer to the error code in case you forget which file and line number you’re supposed to edit.

Find the recent changes that you applied to that file. You may start by looking for missing elements such as comma, semi-colon, a closing bracket, and more. If you still can’t locate the error in the faulty line of code, you may check if it has only one opening ( ) in a single document, look for any code inserted between functions because it is most likely to be broken and check if the code has a semicolon at the end of every line.

It is important to always check the syntax, and make sure that the elements such as the quotation marks are in a proper format. Always remember that quotation marks should never be italic. Also, you should check if the parentheses are balanced, meaning every opening parenthesis should have its closing parenthesis.

If you find this difficult, you may also remove the entire code that was recently added. After removing or editing the code, you may now save the file and upload it back to the server. Go to your WordPress site, and reload the page. Your site shall be working now.

ParseError

ParseError выбрасывается, когда возникает ошибка при разборе PHP-кода, например, когда вызывается функция eval() .

Замечание: Начиная с PHP 7.3.0, класс ParseError наследуется от CompileError . Ранее этот класс расширял класс Error .

The priority of Parse Error should be higher than that of Fatal Error,Parse Error, which has the highest priority among all PHP exceptions. See the following example:
error_reporting ( E_ALL );
test ()
//System output a parse error
?>
error_reporting ( E_WARNING );
test ()
//System output a parse error
?>
error_reporting ( E_ERROR );
test ()
//System output a parse error
?>
error_reporting ( E_PARSE );
test ()
//System output a parse error
?>

/*
* The function eval() evaluate his argument as an instruction PHP
* Then the argument must respect the standar of PHP codage
* In this example the semicolon are missign
*/

/*
* If you run this code the result is different of the result of above code
* PHP will output the standar parse Error: syntax error, .

  How to solve PHP parse/syntax errors

  As a beginning PHP developer, you will encounter an error message from your PHP code, I remember when I kick-started as a PHP developer. When I write code to a certain extent, I’ll get an error message, and it
  piece me off. So that is what we are going to bridge here, if you read and study carefully, you’ll know several things about syntax error and parsing. So to skip much talk, If you are ready let’s get started.

  Prerequisite

  What is a parse error?

  Parse errors are caused by misuse or missing symbols in a particular line of code. The compiler catches the error and terminates the script.

  What is a syntax error?

  If the PHP code contains a syntax error, the PHP parser cannot interpret the code and stops working. For example, a syntax error can be a forgotten quotation mark, a missing semicolon at the end of a line, a missing parenthesis, or extra characters.
  In computer science, a syntax error is an error in the syntax of a sequence of characters or tokens that are intended to be written in a particular programming language. For compiled languages, syntax errors are detected at compile time. A program will not compile until all syntax errors are corrected. What is the difference between parse error & syntax error
  The difference between syntax errors is that parse error happens because of a syntax error. You (the developer) write code that contains a ‘syntax error’. When that code is compiled, the compiler tries to parse your code but cannot which results in a parse error. If you are dealing with an interpreted language, (PHP, ASP, etc.)

  What causes parse & syntax error

  Parse errors are caused by: Unclosed brackets or quotes. Missing or extra semicolons or parentheses.
  A parse error: syntax error, unexpected appears when the PHP interpreter detects a missing element. Most of the time, it is caused by a missing curly bracket «>». To solve this, it will require you to scan the entire file to find the source of the error.

  How to solve parse and syntax error

  • Look at the mentioned code line.
  • More regularly you need to look at preceding lines as well.
  • Look at the syntax colorization!
  • White-space is your friend.
  • You can freely add newlines between operators or constants and strings.
  • Comment out the offending code.

  Conclusion

  You have come to the end of this tutorial, so as a PHP developer, when an error is thrown on you screen, trace that error, from the line of code. And you’ll find out that what causes it is either wrong input of semi-column, curly-brace, Etc..
