PHP functions and @functions

Question

Basically, I\'ve seen people using @ before their function calls, not for every function, but for some kind of extension functions like file_get_contents(

Answer 1

The @ symbol in front of a function prevents errors from being displayed when the function is called.

Answer 2

@function doesn't show any error messages on its HTML output, while a regular function call will.

Answer 3

It's the PHP's error control operator used to suppress any error generated by the function call.

Answer 4

@ is an error control operator. Basically it's suppressing errors.

Answer 5

I have similar doubt about @ used in front of functions. To avoid this I made some verification before the function call. My example is:

if ( is_file($filename) ) $timestamp = filemtime( $filename );
