operators - What is the use of the @ symbol in PHP?

itemprop="text">

I have seen uses of
@ in front of certain functions, like the
following:

$fileHandle =
            @fopen($fileName,
            $writeAttributes);

What
is the use of this symbol?

itemprop="text">

class="normal">Answer

It
suppresses error messages — see href="http://php.net/manual/language.operators.errorcontrol.php"
rel="noreferrer">Error Control Operators in the PHP
manual.
