Question

I have a string that contains some values I need to extract. Each of these values is surrounded by a common character.

What is the most efficient way to extract all of these values into an array?

For example, given the following string:

stackoverflowis%value1%butyouarevery%value2%

I would like to get an array containing value1 and value2

Answer 1

$s = "stackoverflowis%value1%butyouarevery%value2%";
preg_match_all('~%(.+?)%~', $s, $m);
$values = $m[1];

preg_match_all
