Clean Variables in PHP

Sep 02, 2014, by admin

It’s always important to clean/sanitize variables that are submitted via web forms to prevent against all kinds of different malicious threat. Here is a complete function to clean your variables before use.

function clean($value) {
   // If magic quotes not turned on add slashes.
   if(!get_magic_quotes_gpc())

   // Adds the slashes.
   { $value = addslashes($value); }

   // Strip any tags from the value.
   $value = strip_tags($value);

   // Return the value out of the function.
   return $value;
}

 

$sample = “<a href=’#’>This a test</a>”;
$sample = clean($sample);
echo $sample;
