Its syntax: int preg_match_all (string pattern, string string, array pattern_array [, int order])
There are two possible types of order:
PREG_PATTERN_ORDER is the default.
PREG_PATTERN_ORDER: $pattern_array[0] is an array of all complete pattern matches, $pattern_array[1] is an array of all strings matching the first parenthesized regexp, and so on.
PREG_SET_ORDER: $pattern_array[0] contains elements matched by the first parenthesized regexp, $pattern_array[1] contains elements matched by the second parenthesized regexp, and so on.
$userinfo = "Name: R
Title: PHP";
preg_match_all ("/(.*)<\/b>/U", $userinfo, $pat_array);
print $pat_array[0][0]."
".$pat_array[0][1]."\n";
