I have a string:
$string = '😂🧜♂️';
And i want to split in:
$array = ['1F602', '1F9DCU-200D-2642-FE0F'];
How can i do it?
I have already try to use some functions but they doesn’t works because they doesn’t split properly emojis with more then one unicode.
Thank you in advance!
I was about to write the code for splitting emojis using an emoji-unicode dictionary but fortunately the code already exists.
This repo contains everything you need.
You can either use it directly or explore the code and take what you want.

I need to remove the comment lines from my code.
preg_replace('!//(.*)!', '', $test);
It works fine. But it removes the website url also and left the url like http:
So to avoid this I put the same like preg_replace('![^:]//(.*)!', '', $test);
It's work fine. But the problem is if my code has the line like below
$code = 'something';// comment here
It will replace the comment line with the semicolon. that is after replace my above code would be
$code = 'something'
So it generates error.
I just need to delete the single line comments and the url should remain same.
Please help. Thanks in advance
try this
preg_replace('#(?<!http:)//.*#','',$test);

If you want to parse a PHP file, and manipulate the PHP code it contains, the best solution (even if a bit difficult) is to use the Tokenizer : it exists to allow manipulation of PHP code.
Working with regular expressions for such a thing is a bad idea...
For instance, you thought about http:// ; but what about strings that contain // ?
Like this one, for example :
$str = "this is // a test";
This can get complicated fast. There are more uses for // in strings. If you are parsing PHP code, I highly suggest you take a look at the PHP tokenizer. It's specifically designed to parse PHP code.
Question: Why are you trying to strip comments in the first place?
Edit: I see now you are trying to parse JavaScript, not PHP. So, why not use a javascript minifier instead? It will strip comments, whitespace and do a lot more to make your file as small as possible.
I think I need to use the preg_replace function but not sure exactly how to type in the patterns I want to find and replace. Basically, I want to replace this:
: u"x"x",
with this:
: u"x'x",
x means that any characters can go there. But I don't know how to write the x in PHP.
Thank you!
Edit: basically, I want to replace that middle double-quote with a single-quote. And I'll be searching through a big JSON file to do it. Probably should have said this at the start.
You could use this regular expression:
$result = preg_replace('#(: u".*?)"(.*?")#', "$1'$2", $string);
This problem is driving me nuts. Let's say I have a string:
This is a &start;pretty bad&end; string that I want to &start;somehow&end; display differently
I want to be able to remove the &start; and &end; parts as well as everything in between so it says:
This is a string that I want to display differently
I tried using preg_replace with a regular expression but it took off too much, ie:
This is a display differently
The question is: how do I remove the stuff just between sets of &start; and &end; pairs and make sure that it doesn't remove anything between any &end; and &start; segments?
Keep in mind, I'm working with hundreds of strings that are very different to each other so I'm looking for a flexible solution that'll work with all of them.
Thanks in advance for any help with this.
Edit: Replaced dollar signs with ampersands. Oops!
Try this regex /\&start;(.+?)\$end;/g
It looks like it works as desired: https://regex101.com/r/MW5nom/2
I quickly tried it on chrome console using JS, tried converting it into PHP:
"This is a &start;pretty bad$end; string that I want to &start;somehow$end; display differently".replace(/\&start;(.+?)\$end;/g, "")
So I've successfully managed to get a movie title and video title to display via the following code. My question is how do I force the first letters of the output to be captilized?
I know is CSS you would do something along the lines of {text-transform:capitalize;} but how do you implement this sort of thing in PHP?
<?php echo $movtitle.' '.$vidtitle;?>
http://php.net/manual/en/function.ucwords.php
You could've googled that easily!
It sounds like you're looking for the ucwords() function in PHP.
If you want to upper case the first character of each word, use ucwords, or you can use ucfirst (for just the initial character in the string) or strtoupper to upper-case the entire string.
Incidentally, it's worth getting to know the various PHP string functions (and indeed array functions), as time invested in this now will pay dividends later.
<?php echo ucwords($movtitle.' '.$vidtitle);?>
