<form action="#">
<textarea name="tarea" cols="75" rows="10"></textarea><br />
<input type="button" value="htmlspecialchars" onclick="this.form.tarea.value += '\n' + htmlspecialchars(this.form.tarea.value, 'ENT_QUOTES');" />
<input type="button" value="htmlspecialchars" onclick="document.getElementById('entity').innerHTML = htmlspecialchars(this.form.tarea.value, 'ENT_QUOTES');" />
<input type="button" value="show all supported entities" onclick="this.form.tarea.value = specialchars;" />
<div id="entity"></div>
