PHP: Call to undefined function gzdecode()

Question

I am getting a strange error message with the following piece of PHP code (I am not a PHP expert):

if ( $file_loc != NULL ) {
    if ( file_exists($file_loc)         


        

Answer 1

It's not always installed. From the documentation:

Zlib support in PHP is not enabled by default. You will need to configure PHP --with-zlib[=DIR]

The Windows version of PHP has built-in support for this extension. You do not need to load any additional extensions in order to use these functions.

edit: Since this is the accepted answer still, I edited it to add the function suggested as replacement.

function gzdecode($data) { 
   return gzinflate(substr($data,10,-8)); 
}
