Can anyone help me with finding regular expression for the below
$string = "id=A12dk9-mds&name=4950";
I need to find regular expression to find a dynamic value (A12dk9-mds in this example).
i.e the dynamic content between = and &
A simple regex can be used for that.
/id=([^&]*)&/
Explanation:
id= matches id=([^&]*) matches anything but the & symbol as much as possible and returns that& matches the &As long as you know they will always be between a = and a & this will work.
PHP Code:
$string = "id=A12dk9-mds&name=4950";
preg_match('/id=([^&]*)&/',$string, $answer);
print_r($answer[1]);
RegEx is the wrong tool here. This looks like a query string, so let's use PHP's query string parser, parse_str.
$string = "id=A12dk9-mds&name=4950";
parse_str($string, $parsed);
echo $parsed['id'];
As @MarkBaker has stated, the best way to do this is not regex, but parse_str() since you are actually dealing with a query string of a url.
Therefore, the below should work fine:
parse_str($string,$arr);
echo $arr['id']; // A12dk9-mds
