This article will explain in detail how to obtain remote files from php. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Methods: 1, use "file_get_contents ($url)" statement to get; 2, open curl, use curl_init (), curl_setopt () and other functions to get; 3, use "fread (" $url "," rb "), 8192)" statement to get.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

1.file_get_contents

$url = 'http://www.xxx.com/';$contents = file_get_contents ($url); / / if Chinese garbled code occurs, use the following code / / $getcontent = iconv ("gb2312", "utf-8", file_get_contents ($url)); / / echo $getcontent;echo $contents;? >

2.curl

Url = "http://www.xxx.com/";$ch = curl_init (); $timeout = 5 (ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); / / the following two lines / / curl_setopt ($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY) need to be added to the web page that needs to be tested by the user; / / curl_setopt ($ch, CURLOPT_USERPWD, US_NAME.": ".US _ PWD) $contents = curl_exec ($ch); curl_close ($ch); echo $contents

3.fopener-> fread- > fclose

$handle = fopen ("http://www.xxx.com/"," rb "); $contents ="; do {$data = fread ($handle, 8192); if (strlen ($data) = = 0) {break;} $contents. = $data;} while (true); fclose ($handle); echo $contents;file_get_contents, fopen, curl distinction analysis:

1. To use file_get_contents and fopen, allow_url_fopen must be enabled in space.

Method: edit php.ini and set allow_url_fopen = On,allow_url_fopen. Neither fopen nor file_get_contents can open remote files when closed.

2. To use curl, you must open curl in space.

Method: modify php.ini under WIN to remove the semicolon before extension=php_curl.dll, and copy ssleay32.dll and libeay32.dll to C:\ WINDOWS\ system32

The curl extension should be installed under Linux.

It is recommended to use the file_get_contents () method when opening URL to optimize the opening speed.
