Allow certain characters to pass through $_GET?
<p>I wrote a script that when you enter a textbox, it will open an invisible iframe to a .php file with $_GET of what they wrote into the textbox.</p>

<p>However, for example, if I type: '&lt;3' in it, this is what happens.</p>

<p>PHP determins that the $_GET[s] is blank! Users cant put a simple &lt;3 symbol without getting that error.</p>

<p>Another problem is quotes, if I write any quotes, it will end the entire SRC property.</p>

<p>What should I do? Should I do something with javascript, or even PHP? Please let me know!</p>

<p>Thanks!</p>
