Quick Regular Expression problem

php-phan

so this is what the program is trying to find ~poll[Apples,Oranges,Chicken]

Here is what i have the effectively grabs that information

preg_match_all('/~[[A-Za-z0-9\.\,\]]+/', $message, $widgets);

so $widgets[0][0] = ~poll[Apples,Oranges,Chicken]

But when I type this in ~poll[Apples,Oranges,Chicken]HELLO WORLD!

$widgets[0][0] = ~poll[Apples,Oranges,Chicken]HELLO

What is the command or how do i get it to only include the info all the way up until the ending Bracket.

~poll[Apples,Oranges,Chicken]HELLO WORLD!
should make $widgets[0][0] = ~poll[Apples,Oranges,Chicken]

I think you just remove: +

preg_match_all('/~[[A-Za-z0-9\.\,\]]/', $message, $widgets);

php-phan

No because then when I type in ~poll[Apples,Oranges,Chicken]HELLO WORLD!

it only selects ~p

because the + lets you take in more than 1 character. And there is no limit on characters that the user can enter.

dagon

assuming you want everything between ~ and ]

preg_match_all('#\~(.*)\]#', $message, $widgets);

I see.
Well I am not really good with regex.
Will be interesting to see the solution,
when other helpers come by.

php-phan

Awesome that works. The only thing I am kinda worried about is for convention I wanted to keep it where the user can only enter [] . , and the ~. Is there anyway to only allow numbers and letters? If not, well this will do for now :-) lol

Can be nice to get result in this format:
Apples,Oranges,Chicken

<?php
$message = "ABC DEF~poll[Apples,Oranges,Chicken]HELLO WORLD!";
preg_match_all('/~.+\[([(A-Za-z0-9\.\,]+)\]/', $message, $match);
echo '<pre>';
print_r($match);

will return:

Array
(
    [0] => Array
        (
            [0] => ~poll[Apples,Oranges,Chicken]
        )

[1] => Array
    (
        [0] => Apples,Oranges,Chicken
    )

)

and further

<?php
$message = "ABC DEF~poll[Apples,Oranges,Chicken]HELLO WORLD!";
preg_match_all('/~.+\[([(A-Za-z0-9\.\,]+)\]/', $message, $match);
echo '<pre>';
print_r($match);

$food = explode(',', $match[1][0]);
foreach($food AS $item)
	echo $item.'<br />';
/*
Apples
Oranges
Chicken
*/
