Php file_get_contents return NULL invalid Solution

The file_get_contents function is used to collect content on the remote server. However, before using the file_get_contents function, we must enable allow_url_fopen in php. ini.

Problem description

Fopen (), file_get_contents (), getimagesize (), and so on cannot get the content on the network normally. The specific manifestation is that all URL parameters return NULL values.

For windows

Allow_url_fopen enabled

If you can

Re-compile PHP and remove the-with-curlwrapper parameter. Run make clean before compiling.

When windows does not open allow_url_fopen, we use

The Code is as follows:	Copy code
<? Php $ File_contents = file_get_contents (''http: // www.bkjia.com /''); Echo $ file_contents; ?>

However, function_exists can be used to determine whether the function is available.

The Code is as follows:

Copy code

Function file_get_content ($ url ){ If (function_exists ('file _ get_contents ')){ $ File_contents = @ file_get_contents ($ url ); } If ($ file_contents = "){ $ Ch = curl_init (); $ Timeout = 30; Curl_setopt ($ ch, CURLOPT_URL, $ url ); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 ); Curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, $ timeout ); $ File_contents = curl_exec ($ ch ); Curl_close ($ ch ); } Return $ file_contents; }
