How to read remote gzip compressed web pages in php, read gzip compression in php

When retrieving page information of a mall today, use file_get_contents or curl:

Copy code The code is as follows:

$url = 'http://www.xxx.com/21/?type=23′;
$temp = file_get_contents($url);
echo $temp;

They all got garbled code. After checking a lot of content, including the header information of the page, I found that the original page used it.

Similar information, that is, Content-Encoding is gzip, which means that the site has gzip compression turned on. There are many solutions here. Of course, if you use file_get_contents, you can modify it like this:

Copy code The code is as follows:

file_get_contents("compress.zlib://".$url);

Or use curl to do it:

Copy code The code is as follows:

function curl_get($url, $gzip=false){
           $curl = curl_init($url);                                                   curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);                                                 curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);                                         If($gzip) curl_setopt($curl, CURLOPT_ENCODING, "gzip"); // The key is here
           $content = curl_exec($curl);                                                        curl_close($curl);                                                           return $content;                                           }





At the same time, refer to the solution above in the manual, you can also process strings saved in gzip type as follows:

Copy code

The code is as follows:

function gzdecode($data){ $g=tempnam(‘/tmp','ff'); @file_put_contents($g,$data); Ob_start();

Readgzfile($g);

$d=ob_get_clean();
Return $d;
}
