Remove space from the variable in php

In the below code $val whatever value you enter in the text box it is taking a space for example $val="6 " or $val="abc " Below is my simple code

foreach($_SESSION['cart'][$i] as $key => $val)

     {
         if($key=="company_name")
         {
             $company_name_session=$val;
         }
         elseif($key=="product_name")
         {
             $product_name_session=$val;

         }
         else if($key=="unit")
         {
             $unit_session=$val;

         }
         else if($key=="packing_size")
         {
             $packing_size_session=$val;

         }
         else if($key=="qty")
         {
             $qty_session=$val;

         }

         else if($key=="price")
         {
             $price_session=$val;

         }

     }

My Question is how to remove this space while declaring a variable in php .

trim() should do it, if you're interested in removing the spaces around the text.

 $val = trim($val);

You could also use the rtrim(), which trims the end.

Or if you wanted to remove all spaces in the variables, you could use str_replace()

$val = str_replace(' ', '', $val);

Edit:
And as Nathaniel mentioned, you can also use preg_replace(), if you want to use regular expressions for more complex rules.
