说明

gzfile(string $filename, int $use_include_path = 0): array|false

This function is identical to readgzfile(), except that it returns the file in an array.

参数

filename: The file name.
use_include_path: You can set this optional parameter to 1, if you want to search for the file in the include_path too.

返回值

An array containing the file, one line per cell, empty lines included, and with newlines still attached, 或者在失败时返回 false.

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

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;

}

?>
