Php first letter of word

PHP: Get the first character in a string.

This is a short guide on how to get the first character of a string in PHP. As an added bonus, I will also show you how to get the first two characters of a string.

We used two different approaches here.

Using the first approach, we treat the string like an array. i.e. We use the index position of the character to access it. This is possible because strings in PHP can be treated like character arrays (basically, a string is just an array that consists of characters).

In the second approach, we used the PHP function substr, which returns a part of a string. With the substr function, there are three parameters:

1. The string in question.
2. The index to start at (we set this to 0 because we want to start at the very beginning of the string).
3. The length that we want to return (we set this to 1 because we only want the first character).

mb_substr and special characters.

If there is a chance that your string contains special characters such as “ö” or “ë”, then you will need to use the mb_substr function. This function is the multi-byte safe version of substr. If you use the substr on a string that contains special characters, then you might end up with jumbled characters and / or the black diamond question mark “replacement character”.

Example of mb_substr being used to get the first character of a string that contains special characters:

//Set the header to utf-8 for example purposes. header('Content-Type: text/html; charset=utf-8'); //Example string. $string = 'öëBC'; //Use mb_substr to get the first character. $firstChar = mb_substr($string, 0, 1, "UTF-8"); //Print out the first character. echo $firstChar;

Note that this function allows you to specify the encoding as a fourth parameter!

Anyway; hopefully you found this short tutorial helpful!

Thread: PHP: Find 1st Letter of EVERY word in a string

Awesome!

PHP: Find 1st Letter of EVERY word in a string

How would I find the first letter of a word contained within a string using PHP.

$string = "Lots of words in this string";

I would want to find L,O,W,I,T,S. Any thoughts? I know how to find the very first letter, but this is slightly more complicated.

Re: PHP: Find 1st Letter of EVERY word in a string

split the string up into an array, then use for loop to go through the array, checking the first letter using substring functions.

Re: PHP: Find 1st Letter of EVERY word in a string

stupid idea : with a regular expression and a capturing pattern.
something like

preg_match_all("/(\S)\S*/i",$string,$array,PREG_PATTERN_ORDER)

then $array[0] or $array[1] should contain all the first letters. hopefully (my regexp may be totally wrong).

but of course exploding the string is simpler

Gee! These Aren’t Roasted!

Re: PHP: Find 1st Letter of EVERY word in a string

real quick code. debug on your own. probably not the fastest solution by far

$string = «Lots of words in this string»; $words = explode(» «, $string); $letters = «»; foreach ($words as $value)

if you want the spaces and commas in there, then put those in the for loop too.

Awesome!

Re: PHP: Find 1st Letter of EVERY word in a string

Thanks for the ideas. I have managed to accomplish my goal by splitting the string into an array. I just wondered if their was an alternative.

Re: PHP: Find 1st Letter of EVERY word in a string

Not just saying this but explode has got to be in my top 3 most used commands in PHP.

I was only reluctant to use it in this case because I wanted to see if their were any alternatives and wanted to increase my PHP knowledge.

Again, Thanks to the community
