正则表达式找到并替换为preg_match_all

Question

I'm kind of staring blind on this one, trying to use preg_match_all to find texts placed in between hashes

##START of the text##
the text <b>starts</b> here etc
##END of the the text##
##START of the text 2##
Other version stringtext <b>starts</b> here etc
##END of the the text 2##

whatever I try, one time I get of the text and other time only between hashes, can anybody help me with the regex?

Answer 1

$string = '##START of the text##
the text <b>starts</b> here etc
##END of the the text##
##START of the text 2##
Other version stringtext <b>starts</b> here etc
##END of the the text 2##';

preg_match_all('/##START.+?##[
](.+?)##END/s', $string, $matches);
// look for any characters between ##START and ##END, 's' will make it match newlines as well

print_r($matches[1]);

Will output:

Array
(
    [0] => the text <b>starts</b> here etc

    [1] => Other version stringtext <b>starts</b> here etc

)
