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)) {
           
$data .= gzread($file, 1024);
        }
       
gzclose($file);
    }
    return
$data;
}
?>
