Suppressing PHP warnings for specific functions using the @ ‘at’ symbol
Some PHP functions, return an error rather than gracefully exit.
Lets take the file_get_contents() function as an example:
$contents = file_get_contents('/path/to/file.html');
If ‘file.html’ doesn’t exit, then it will return something similar to the following:
<b>Warning</b>: file_get_contents(path/to/file.html): failed to open stream: No such file or directory in <b>/Users/user/Documents/file.php</b> on line <b>13</b><br />
This is of course, problematic as we’re saving the return value into the $content variable to be output later!
The solution? The magic @ symbol. Simply append it do the front of the function, and warnings are suppressed:
$contents = @file_get_contents('/path/to/file.html');
That’s it! Now if ‘file.html’ doesn’t exist, $contents will simply be empty, which we can check for.
