php - Find next word after colon in regex -

i getting result return of laravel console command

some text as: 'nerad'

now tried

$regex = '/(?<=\bsome text as:\s)(?:[\w-]+)/is';

preg_match_all( $regex, $d, $matches );

but returning empty. guess wrong single quotes, need change regex.. guess?

note no match because ' before nerad not matched, nor checked lookbehind.

if need check context, avoid including match, in php regex, can done \k match reset operator:

$regex = '/\bsome text as:\s*'\k[\w-]+/i';

the output array structure cleaner when using capturing group , may check unknown width context (lookbehind patterns fixed width in php pcre regex):

$re = '/\bsome text as:\s*\'\k[\w-]+/i'; $str = "some text as: 'nerad'"; if (preg_match($re, $str, $match)) {     echo $match[0]; } // => nerad
