Array & Loop Example

Suppose we have a form and we want from user to select from a list of check boxes and check his favorite choices, post that data as an array and we want to display that data by calling array and arranging it in a loop. Then for this purpose consider following example.

Form Code

PHP Code – Retrieve Data From Array and Display It Through A Loop


for ($i=0; $i<count($_POST['pick']);$i++)
	{
$displaydata=$_POST['pick'][$i]."
";
echo "$displaydata";
        }
?>

In the above example we have collected the data from check boxes in form of arrays named as pick[] and we have sent it to another PHP page where it is displayed through a for loop.

PHP Arrays

An array is a data structure that stores one or more values in a single value. In more detail ‘An array’ in PHP is actually an ordered map. A map is a type that maps values to keys. This type is optimized in several ways, so you can use it as a real array, or a list (vector), hashtable (which is an implementation of a map), dictionary, collection, stack, queue and probably more. Because you can have another PHP array as a value, you can also quite easily simulate trees.

An array can be created by the array() language-construct. It takes a certain number of comma-separated key => value pairs.


$my_array = array("somearray" => array(6 => 5, 13 => 9, "a" => 42));
 
echo $my_array["somearray"][6];    // Output: 5
echo $my_array["somearray"][13];   // Output: 9
echo $my_array["somearray"]["a"];  // Output: 42
?>


$programming_array[0] = "PHP";
$programming_array[1] = "ASP";
$programming_array[2] = "AJAX";
$programming_array[3] = "JSP";
 
echo "Two of most valuable programming resources are " . $programming_array[0] . " & " . $programming_array[2];
 
// Output:
// Two of most valuable programming resources are PHP & AJAX
?>
