essentially i'm setting wifi speed calculate in javascript document variable,so can save variable value in database other information instance.

the javascript code pretty long don't know if should copy whole code in , set equal variable or if there's syntax set variable.

i've seen:

<script type="text/javascript" src="file.js"></script>

online calling javascript file not sure how value , store in variable.

$js = file_get_contents( 'http://www.example.com/javacsript.js');  $value = trim( str_replace( array( "document.write('", "');"), '', $js));  echo $value;

hope you
