This function is not binary safe. (intentionally, or not, that's the question :)

In PHP4.4.1 I noticed that gzfile only reads up to 8190 bytes per line. I had a 20K SQL query that was cut into 3 parts - and wondered why the SQL server complained.
Reading an uncompressed file with the file() command works as expected.

A quicker way to load a gziped file in a string :
<?php
function gzfile_get_contents($filename$use_include_path 0)
{
    
//File does not exist
    
if( !@file_exists($filename) )
    {    return 
false;    }
    
    
//Read and imploding the array to produce a one line string
   
$data gzfile($filename$use_include_path);
   
$data implode($data);
   return 
$data;
}
?>

This works similar to gzfile() but it returns the file in a string instead of an array and doesn't write it to stdout compared to readgzfile.

Note: unlike the usual file-functions filesize won't work here, since the length-parameter of gzread refers to the uncompressed length, while filesize returns the size of the compressed file.

<?php
function gzfile_get_contents($filename$use_include_path 0) {
    
$file = @gzopen($filename'rb'$use_include_path);
    if (
$file) {
        
$data '';
        while (!
gzeof($file)) {
            
$data .= gzread($file1024);
        }
        
gzclose($file);
    }
    return 
$data;
}
?>
