ereg in php5.1.4

Post by Charles256 »

Code: Select all

if (ereg("[^:space:a-zA-Z0-9\.]",$author2))
	  {
	    echo 'Only use spaces, periods, and alhpa numeric charecters.';
	    $error=1;
	  }
this works fine if the variable has alpha numeric and periods but as soon as I throw in a space it goes haywire, any ideas why?

Moved to Regex.

Wish I could help, but I don't know much about the posix engine... would be easy to do in PCRE :?

this might not work, but try '\s' rather than :space: ...

You can use: \s as $phpNut said, but this will allow new lines and tabs and not just spaces. Is that ok?

[:space:] is the macro in Posix, I believe, but why use it when PCRE is faster and will be supported in future versions of php where Posix won't?
