Sum string length of all array values

<?php
setcookie("Auction_Item", "Luxury Car", time()+2*24*60*60); 
if(isset($_COOKIE["Auction_Item"])){ 
    echo "Auction Item is a  " . $_COOKIE["Auction_Item"]; 
} else{ 
    echo "No items for auction."; 
} 
?>

Okay so this php code simply sets a cookie and gives the value, I need to write a function that after accepting a boolean parameter as TRUE returns the sum of length of all cookies presented into the request.

if ($val = true){
    $cookies = $_COOKIE
    $strVal = "";
    $countVal = count($cookies);
    for ($x = 0; $x < $countVal; $x++) {
        $strVal = $strVal . $cookies[$x].$val
    }
    echo 'Sum of length of all cookie values' . strlen($strVal)

I've tried this, but it doesn't seem to work.

Solution

  • The answer from MaryNfs is correct but missing one important thing from your original code. Try the following:

    setcookie("Auction_Item", "Luxury Car", time()+2*24*60*60); 
if(isset($_COOKIE["Auction_Item"])){ 
    echo "Auction Item is a  " . $_COOKIE["Auction_Item"]; 
} else { 
    echo "No items for auction."; 
} 

$val = true;  //Set the variable $val

//You had $val = true, setting $val to true.  
//You need to evaluate it as true or false so use === to compare
//Using = sets the variable's value

if($val===true) {    
    $joinedCookies = "";    
    foreach ($_COOKIE as $key=>$value) {
        $joinedCookies = $joinedCookies . $value;
    }
    $joinedCookiesLength = strlen($joinedCookies);
    echo 'Sum of length of all cookie values ' . $joinedCookiesLength;
}

    Once the $_COOKIE is set, the above should return:

    Auction Item is a Luxury Car

    Sum of length of all cookie values 36

    Your code was missing ; after three lines which would break things so keep an eye out for that as well.
