preg_match

[dkin]

How can I use preg_match to retrieve the place of a empty space in a string?

As far as I know preg_match has no option to get the position where something was found. Surely you could apply string function to the match to get the length of strings each subpattern found or something, but I'd think strpos() would be far easier in most cases.

If you just want to use preg_match() to see if a space is in the string, use:
preg_match ("/ /", "Hello world");

If you want the actual locaction of the space in the string, use:
$text="Hello world";
$textToFind=" ";
$stringPosition=strpos($text,$textToFind);
