Execution Operators

Execution Operators

PHP supports one execution operator: backticks (). Note that these are not single-quotes! PHP will attempt to execute the contents of the backticks as a shell command; the output will be returned (i.e., it won't simply be dumped to output; it can be assigned to a variable). Use of the backtick operator is identical to . `````shell_exec`

Voorbeeld: Backtick Operator

<?php
$output = `ls -al`;
echo "<pre>$output</pre>";
?>

Opmerking: > The backtick operator is disabled when is disabled. shell_exec

Opmerking: > Unlike some other languages, backticks have no special meaning within double-quoted strings.
