在每个循环中输出一个$ _SESSION变量

Question

Im having an issue with outputting a certain session inside a foreach loop, a session that contains a certain string of characters:

function cart(){

    foreach($_SESSION as $name => $value){


    }
}

doing so ^, outputs all the sessions, and i want it to output only the sessions that contain the $name cart_.

If any of you has an idea on how to do so, it will be much appreciated.

It looks like you could make use of strpos:

function cart() { 
    foreach($_SESSION as $name => $value) {
        if(strpos($name, 'cart_') !== FALSE) {
             //echo here
         }
     }
}
