PHP file read not working
On a server I have the file some.php. I try to read the content开发者_Go百科s using file_get_content
and fread
. Both these don't read my content.
If I try some other URL like yahoo.com, these functions are reading the contents. Why does this happen?
$my_conetn = file_get_contents("http://example.com");
echo $my_conetn;
The above snippet is not working.
$handle = fopen($filename, "r");
$contents = fread($handle, 20);
echo $contents;
fclose($handle);
Also the above snippet is not working.
How to check my server? Is there any file read operation locked or not?
edit: I am not sure, but it is only my server file that can't be read. I can read the other server links. So I contact my hosting provider, then I get back to you guys/gals.
When using file functions to access remote files (paths starting with http:// and similar protocols) it only works if the php.ini setting allow_url_fopen
is enabled.
Additionally, you have no influence on the request sent. Using CURL is suggested when dealing with remote files.
If it's a local file, ensure that you have access to the file - you can check that with is_readable($filename)
- and that it's within your open_basedir
restriction if one is set (usually to your document root in shared hosting environments).
Additionally, enable errors when debugging problems:
ini_set('display_errors', 'on');
error_reporting(E_ALL);
