How would I use a switch case statement to run through an array?

[Stuart_Westgate]

I'm trying to use an array to go through a switch case statement.

This is my code at present but I feel something is missing as it's not working > Can someone please help?

 

 

$stringArray = array('socks:', '', 'jacket', 'boxers', 'trainer', 'tshirt', 'bag', 'tie');

 

$pos = strpos($statusItemCheck, $stringArray[0]);

 

$imageValue = "images/"; //Value of

 

switch($pos){

case $stringArray[0]:

$imageValue .= "socks.PNG";

break;

case $stringArray[1]:

$imageValue .= "hat.PNG";

break;

case$stringArray[2]:

$imageValue .= "jacket.PNG";

break;

default:

$imageValue .= "questionMark.PNG";

break;

}

A switch-case is not a loop, it's a control statement. Just like IF.

You need to use a loop around it, if you want to check every element of an array.

Try something like this:

<?PHP

//### Set this for testing purpose
$statusItemCheck = 'jacket';

//### Path of images
$imageValue = 'images/';

//### Array of items
$stringArray = array('socks' => 'socks.png',
				 'hat' => 'hat.png',
				 'jacket' => 'jacket.png',
				 'boxers' => 'boxers.png'
				 );

//### Check if the item exists in the array
if(!isSet($stringArray[$statusItemCheck])) {
echo 'Item does not exist.';

//### Item exists, add the image filename to image value
} else {	
$imageValue .= $stringArray[$statusItemCheck];

echo $imageValue;
}

?>

If the pics are always going to have the standard name format of "item".png, you could do this

 

$availableItemsArray = ("socks", "jacket", "hat", "boxers");

 

$testItemsArray = ("jacket", "boxers", "monkey hair gloves", "socks", "jodhpurs");

 

$arrayLength = count($itemsArray); // you could put this in the for loop below .. but its better to only count the array one time and save it, than to count it on each iteration

 

for($i=0; i < $arrayLength; $i++){

 

 

if(in_array($testItemsArray[ $i ], $availableItemsArray) // grabs each item to be compared one by one .. and looks if it is in the array of available items

{

echo "images/" . $testItem[ $i ] . ".png";

}else{

echo "Item doesn't exist";

}

 

}

 

 

You might want to put a strtolower() in there somewhere to deal with capitalization discrepencies
