I've been searching a lot but i cannot find anything similar to my problem. I've found this link but i don't think they really answered the question.
Let say i have this string
$my_string = "I am with a [id]123[/id] and [id]456[id]";
I want to get all the number between [id][/id]. I only have this function to get the string between.
function get_string_between($string, $start, $end){
$string = ' ' . $string;
$ini = strpos($string, $start);
if ($ini == 0) return '';
$ini += strlen($start);
$len = strpos($string, $end, $ini) - $ini;
return substr($string, $ini, $len);
}
$fullstring = 'I am with a [id]123[/id] and [id]456[id]';
$parsed = get_string_between($fullstring, '[id]', '[/id]');
But this function only returns the first string found on $fullstring. Maybe i can get 123,456
or in array form array('123','456'). I really am stuck with this.

您可以简单地使用PHP的preg_match_all
功能以及以下正则表达式
~\[id\](.*?)\[\/id\]~
喜欢
$my_string = "I am with a [id]123[/id] and [id]456[/id]";
preg_match_all("~\[id\](.*?)\[\/id\]~",$my_string,$m);
print_r($m[1]);
