Question

I use YAML to get MySQL schema and i need to parse only these kind of strings CHAR(60) or VARCHAR(90) etc..

Parsing result would be like this:

array('CHAR', 60);
array('VARCHAR', 90);

Answer 1

The following regex will do it. If these don’t occur one per line, you should also add the \b boundaries after the opening slash and before the closing one.

$s = "VARCHAR(90)";
$matches = array();
preg_match("/([A-Z]+)\(([0-9]+)\)/", $s, $matches);

// Then use the matched values into your array.
array($matches[1], $matches[2]);

EDIT: Had the $matches array keys wrong the first time. Should be 1 & 2, not 0 & 1.
