It’s very simple, just one function can do it!

The following teaches you how to use preg_match_all in php to match pictures in articles                                                                                                                        

##preg_match_all function:

int preg_match_all ( string pattern, string subject, array matches [, int flags] )

Perform a global regular expression matching

Search in the subject for all content that matches the regular expression given by pattern and put the results into matches in the order specified by flags.

After the first match is found, subsequent searches start from the end of the previous match.

flags can be a combination of the following flags (note that it does not make sense to use PREG_PATTERN_ORDER and PREG_SET_ORDER together):

PREG_PATTERN_ORDER Sort the results so that $matches[0] is an array of all pattern matches, $ matches[1] is an array of strings matched by the subpattern in the first bracket, and so on!

$pattern="//";
$con = file_get_contents("https://www.jb51.net/news/jb-1.html");
preg_match_all($pattern,$con,$match);
print_r($match);
