getting the full string of a certain text

[jansky]

hi all

pardon me

i have a string = ' the quick brown fox http://global.com/file/helloworld.html';
and findstring = 'file/helloworld.html';

now when i search findstring to string the outcome would be the complete string http://global.com/file/helloworld.html';

is this possible?

and how do i achieve this

tnx in advance

You could use [man]preg_match/man or [man]preg_match_all/man, something like:

preg_match_all('#https?://\S*'.preg_quote($findString, '#').'\b#i', $string, $matches);
print_r($matches);
