Error Control Operators in PHP : Tutorial

@ is the Error control operator in PHP.

When prefixed to an expression, any error/warning messages that might be generated by that expression will be ignored.

i.e. It suppresses error/warning messages.

Example 1:

<?php

echo 2/0; //Gives warning :  Division by zero

echo @(2/0); echo 2/0; //@ suppresses the warning

}

?>

Output


Warning: Division by zero in I:\xampp\htdocs\xampp\Tutorials\ComparisonOpearatorsExample.php
on line 3

In the above example, we do not get the warning "Division by zero" when we add Error Control operator before the expression 2/0.

Example 2:

<?php

method(); //Gives Fatal Error : Call to undefined function methodCall()

echo @(2/0); echo 2/0; //@ suppresses the Fatal error

}

?>

Output


Fatal error: Call to undefined function methodCall() in 
I:\xampp\htdocs\xampp\Tutorials\ComparisonOpearatorsExample.php on line 5

In the above example we are calling a function which has not been defined, that a fatal error is thrown.
But when the function call is prefixed by @ operator, the fatal error is not displayed.
