Re: array walk?

Looks like the answer is in the manual entry for array_walk_recursive http://php.net/array_walk_recursive *Note: * If *funcname* needs to be working with the actual values of the array, specify the first parameter of *funcname* as a reference<http://www.php.net/manual/en/language.references.php>. Then, any changes made to those elements will be made in the original array itself. Try using a wrapper around strip_tags which tags a reference as its first argument function array_walk_strip_tags(&$string){ $string = strip_tags($string); } PHP is essentially only passing a copy of $a[i] and stripping the tags from the copy without changing the actual values of $a. Passing by reference ensures that you modify the entries in $a itself. How this is handled below the hood is slightly more complex and I don't have a ton of experience with how PHP specifically handles that sort of thing, but it looks like that will at least point you in the right direction. -Michael On 6/28/07, Juan Ignacio Borda <webmaster@baexporta.gba.gov.ar> wrote:
