<?php

function valadate($x){
$x=mysql_real_esape_string($_POST['$x']); // should this - $_POST['$x'] actually be $x !?
return($x);
}

echo valadate($x="john");

?>

mysql_real_esape_string is spelled incorrectly. it's mysql_real_escape_string.

WHY DONT THIS WORK GOING GRAY LOL

<?php

//CREATE THE FUNCTION.

function valadate($x){
$x=mysql_real_escape_string(strip_tags(htmlentities($x, ENT_QUOTES)));
return($x);
}

// ADD A VARIABLE AS WHAT EVER.
$redarrow=$_POST['redarrow'];

// SET THE VARIABLE AS WHAT EVER
$redarrow="redarrow";

//ADD THE FUNTION TO THE VARIABLE.
$redarrow=valadate($x=$redarrow);

//ECHO THE VARIABLE WITH ADDED FUNCTION.
echo $redarrow;

?>
