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().

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

Note: The backtick operator is disabled when safe mode is enabled or shell_exec() is disabled.
