显示来自文本区域的php中的javascript代码

Question

I need the user to enter a complete code in a textarea, it appears in php programming ...

In the code this is with error cutting the parameters adding "[removed]", the input of the code was tested and it is ok, but to appear the code happens this conversion ...

Simple code entry:

    public function addchat($el) {
    $conteudo = $el['ed_json'];
    $echohtmladdchat = $conteudo['zcodigo'];

    return $echohtmladdchat;
}

The code insert:

<!--Start of Zendesk Chat Script-->
<script type="text/javascript">
window.$zopim||(function(d,s){var z=$zopim=function(c){z._.push(c)},$=z.s=
d.createElement(s),e=d.getElementsByTagName(s)[0];z.set=function(o){z.set.
_.push(o)};z._=[];z.set._=[];$.async=!0;$.setAttribute("charset","utf-8");
$.src="https://v2.zopim.com/?2SkHVyd50jJGoAuy5eKmVqknfvdGQpRM";z.t=+new Date;$.
type="text/javascript";e.parentNode.insertBefore($,e)})(document,"script");
</script>
<!--End of Zendesk Chat Script-->

As the code appears:

<!--Start of Zendesk Chat Script-->
[removed]
window.$zopim||(function(d,s){var z=$zopim=function(c){z._.push(c)},$=z.s=
d.createElement(s),e=d.getElementsByTagName(s)[0];z.set=function(o){z.set.
_.push(o)};z._=[];z.set._=[];$.async=!0;$.setAttribute("charset","utf-8");
$.src="https://v2.zopim.com/?2SkHVyd50jJGoAuy5eKmVqknfvdGQpRM";z.t=+new Date;$.
type="text/javascript";e[removed].insertBefore($,e)})(document,"script");
[removed]
<!--End of Zendesk Chat Script-->

为了获得代码，请使用echo htmlentities($js);
