有没有办法使用preg表达式来搜索字符串并放入数组？ PHP

Ive been trying to use preg_split but it's not working very well, this is how I'm using it:

$html_str = '<span class="spanClass" rel="rel span">Text Span</span>';

$arrTemp = preg_split('/\<span class=\"spanClass\" rel=\"(.+?)\"\>(.+?)\<\/span\>/', $html_str);

So I would get this 2 '(.+?)' variables into an array(span rel and Text Span).

I'm probably not thinking about it in the best possible way to solve my problem, but the fact is that my string will have more than one <span> mixed with trash html and I need to separate only the <span> content in an array. Any better ideas?

First of all preg_split is the wrong function, you really meant preg_match from the syntax of regex that you seem to be using.

Correct use would be:

$html = '<span class="spanClass" rel="foo bar">Text Span</span>';
preg_match("/<span.*rel=[\"']([^\"']+)[\"'][^>]*>([^<]+)<\/span>/", $html, &$A);
print_r($A);

This outputs:

Array
(
    [0] => <span class="spanClass" rel="foo bar">Text Span</span>
    [1] => foo bar
    [2] => Text Span
)

So above uses preg_match; $A[0] contains the entire line $A[1] the rel= stuff and $A[2] the Text Span stuff.
