PHP Regexp problem

PHP
1

Hi,

I have a form with a textarea that gets filled with content like:

[CONTENT id=77165][CONTENT id=77164][CONTENT id=77162][CONTENT id=77159][CONTENT id=77158]

I need to extract only the integer id’s.

I have so far:


$input = "[CONTENT id=77165][CONTENT id=77164][CONTENT id=77162][CONTENT id=77159][CONTENT id=77158]";
$regex = '#\\[CONTENT id="(.*?)"\\]#s';
preg_match_all($regex, $input, $matches, PREG_SET_ORDER);

print '<pre>';
print_r($matches);
print '</pre>';

I get an empty array.

I’d like to achive an array with each id as an array element.

How can I do that?

Thanks

regex is looking for
[CONTENT id=“77165”]
but you have
[CONTENT id=77165]

Nice.

It was my bad. I removed the " from the input string and didn’t change the regexp.

But I still can’t get each id only as array elements. :frowning:

In addition to what crmalibu pointed out, if you know you only want to capture digits, IMHO you should use (\d)+ instead of the everything atom

Thanks for the help.

I now have:


$regex = '/(\\d+)/';
preg_match_all($regex, $input, $matches, PREG_PATTERN_ORDER);
print_r($matches);

And I get what I needed. :slight_smile:
