Why another embedded library?

The original embedded library is fine if your goal is to add limited PHP scripting support to your application when the amount of PHP script runs remains small and you do not need concurrent script runs (in multi-threaded applications). If you need to use embedded PHP in a multi-threaded environment, need higher speeds when dealing with multiple script runs or you wish to manipulate INI settings which fall under the category PHP_INI_SYSTEM or PHP_INI_PERDIR you will need the EMBED2 SAPI module.

How do I run concurrent scripts in multi-threaded mode?

Typically you request the php environment to startup at program startup by invoking php_embed2_init(). In each thread function request a thread safe resource identifier by invoking TSRMLS_FETCH(). If you call other functions from within the thread function try to use the TSRMLS_xx macros as much as possible. When you need to run a script invoke the php request environment by calling php_embed2_req_init(), execute a script with the php_embed2_exec_* functions and when done with the request shut it down by using php_embed2_req_shutdown(). You are allowed to run multiple php_embed2_exec_* functions in the same request space if you need the script globals to cross the function calls. On application shutdown you must have shut down the php environment using on of the php_embed2_shutdown* functions.

I’m not using threads in my application, why should I use this library?

Efficiency! With the embed2 library you can have multiple separate requests / script runs without the need of initializing and shutting down the entire PHP environment. The original embedded library functions the same way as a CLI environment as for each script run the following happens:

• php environment startup
• php modules startup
• php request startup
• script execution
• php request shutdown
• php modules shutdown
• php environment shutdown

When running a lot of scripts during the lifetime of your application this is not optimal. With the embed2 library you will only have to startup the php environment and php modules once and for each script run only the following happens:

The embed2 library allows you to:

• select an alternate php.ini configuration file
• select where php output and error output should go (stdout, file, callback or char*)
• easy install userland callback function without needing to write an extension module
• execute php scripts from char* using internal memory_stream handler for zend
• use embed2:// stream combined with callback function to implement embedded/on-the-fly-generated script retrieval

Possible Future enhancements?

• easy setup of ini arguments before engine start
• per thread configuration of easy callback function (so it can be changed on the fly even within request space)
• .
• your idea?

How do I embed Javascript in PHP code?

The content of the PHP page is as follows: I need to insert the following JavaScript code instead of the : So what I did is placed the code in to a code.js and instead of the in the PHP code I inserted Solution 1: The problem is that you have inserted the tag script as a non-templated tag, here is the right form: Obviously, if the .js is located in the right place, it will be loaded. Solution 2: The content of the php page is as follows: I need to insert the following javascript code instead of the : So what I did is placed the code in to a code.js and instead of the in the php code I inserted Question: I am trying to create a function when called, will write PHP code into my document.

How do I embed Javascript in PHP code?

I have a HTML form and PHP code. In my form, I have a textbox and a textarea. Within both, I have included the «disabled» option. I want both textboxes to remain disabled until the user decides to click the «Edit» button, in which case both textboxes should be enabled so changes can be made and the output once again saved. According to the research I have done, the only way to do this is to use javascript, so I have included the following code within my PHP;

if (isset($_POST['edit'])) < echo ""; > 

if (isset($_POST['edit'])) < echo ""; > 

I am not receiving any errors, the textboxes just remain disabled after I click the Edit button. Could anyone help me with this? Thanks in advance.

This is a better approach for these kind of problems :

if (isset($_POST['edit'])) < ?>  

Try use onclick on your Button

The second approach seems correct, but you’re missing ; there. Also, you haven’t put any newline characters.

   ?> 

You don’t need to echo the whole thing. You can simply put it out of the PHP and keep it inside a if block.

Also, I’ve kept the alert to check if your code structure is proper. If you’re getting the alert on clicking the edit button, means you’re on the right path. You just need to workout on the JS.

If not, something wrong with your edit button and the form POST

How properly insert JavaScript code in to PHP?

I have a PHP based website. I need to add a JavaScript code in to the head. I would like to include the code in to a small JavaScript file and call it from within PHP page. The code starts with . So I tried to save the code in to code.js and in the head of my website’s PHP code I put

So what I did is placed the code

in to a code.js and instead of the in the PHP code I inserted

The problem is that you have inserted the tag script as a non-templated tag, here is the right form:

Obviously, if the .js is located in the right place, it will be loaded.

You haven't seen the tag in your code probably because you've inspected the HTML with an HTML inspector, but that tool is not always capable to show you malformed tags. For be sure to see the right HTML result, you must view the souce code (usually, right click on the web page via browser and "show source code" option is there).

The content of the php page is as follows:

Inserting PHP code into the InnerHTML of a SELECT Tag

I am trying to create a function when called, will write PHP code into my document.

For example (original code) .

The SELECT-Tag above connects to my database to retrieve the data.

When i try using a JavaScript function to insert the retrieved data (seen below)

function impressora_select()< var imp = document.getElementById("impressora_div").innerHTML = "Selecione2.  ?>" > 

All that is returned(inserted) is a select option called " Selecione2. " How do i make this function insert data from my database into my document via innerHTML?

Update with changes from Hasan Delibas.

  functions3.php -> select name='impressora' value='selecione'>Selecione2.  ?> 

But is retuning this error.

 portnew.php:5 GET portnew.php:7 Uncaught ReferenceError: $ is not defined at portnew.php:7 (anonymous) @ portnew.php:7 porntnew.php:42 Uncaught ReferenceError: $ is not defined at portnew.php:42 

First create new .php file for change inside #impressora_div

You can not use php web browser side. You but you can call .php file with ajax.

Как написать js в php файле?

Пробую вот такой способ, но выдает ошибку. Как подключить правильно?

 $(document).mouseup(function () < $('.header__burger').click(function (e) < e.preventDefault() $('.header__nav').toggleClass('header__nav--active') >) >) $(document).mouseup(function (e) < var $target = $(e.target) if ($target.closest('.header__menu').length == 0) < $('.header__nav').removeClass('header__nav--active') >>) " ?>

кавычки здесь поставь одинарные

Команда echo не запускает скрипты, она выводит текстом все что в нее всунуто.
Т.е. максимум, при исправлении ошибок синтаксиса, в вашем примере вы получите код js написанный в виде текста, например на странице или в консоли или где вы запускаете этот php, для того, чтоб код сработал, вам нужно выйти за рамки php , например -

И открыть на сервере. Не знаю где вы такому бреду нахватались, но теперь понимаю уровень персонала X5)

JeorgeLaght, я пропущу оскорбления, но с чего вы взяли, что я путаю echo и print?

P.S. Бред - считать, что фронтендеры в Х5 пишут на PHP)
