<?php

        $x[] = '/';
        $x[] = 'a';
        $x[] = '>';

        $x = array_reverse($x);

It seems like $x can also be of type true; however, parameter $array of array_reverse() does only seem to accept array, maybe add an additional type check?

        // améliore l'obscurcissement en éliminant les retours à la ligne et les espaces
        $output = '<script type="text/javascript">'
                . 'var l=new Array();';

        foreach ($x as $i => $value) {
            $output .= 'l[' . $i . "] = '" . $value . "';";
        }

        return $output . ('for (var i = l.length-1; i >= 0; i=i-1) {'
                . "if (l[i].substring(0, 1) === '|') document.write(\"&#\"+unescape(l[i].substring(1))+\";\");"
                . 'else document.write(unescape(l[i]));'
                . '}'
                . '</script>');
