Regular Expression

Hi.. I'm trying to use regular expressions to locate strings that contain numbers, and then assign that number to a variable

I would really appreciate any help with my code below that does not work correctly:

if (eregi("^[0-9]", $string))
{$input = eregi("^{[0-9]",$string)} }

Thanks

Jeff

Hi Jeff,

if (eregi("^[0-9]", $string))
{$input = eregi("^{[0-9]",$string)} }

This will match only a single digit at the start of a string. If you'd like to match all numbers within a string change to

if (preg_match("[0-9]+", $string))
{preg_match_all("[0-9]*", $string, $input) }

$input will then be an array containing all matches.

Sorry for the change from posix to perl but I'm more used to it 🙂

Greets,

Thanks for your help, Dominique,

When I use your example, I get this error msg:
"Unknown modifier '+"

Can the "+" only be used with certain PHP versionS?

Thanks again, Jeff
