inline php error

hello everybody. I use the plugin inline php, but when i use it i get this error:

Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE or ‘$’ in /home/apolloni/public_html/test/wp-content/plugins/inline-php/exec_php.php5(4) : eval()’d code on line 1

Can anyone help me with it?

This is the code in the file:

<?php
function exec_php($matches){
try {
eval(‘ob_start();’.$matches[1].’$inline_execute_output = ob_get_contents();ob_end_clean();’);
} catch (Exception $e) {
}
return $inline_execute_output;
}
?>
