PHP array

Image
  An array stores multiple values in one single variable. In PHP, the array() function is used to create an array. Example: <?php $pets = array ( "dog" , "cat" , "rabbit" ); echo $pets [ 0 ] . "," . $pets [ 1 ] . "," . $pets [ 2 ]; ?> Output: dog,cat,rabbit An array is a special variable, which can hold more than one value at a time. If you have a list of student names, storing the names in single variables could like this, $name1 = "Peter" $name2 = "Mickle" $name2 = "Bravo" However, what if you want to loop through the names and find a specific one? And what if you had 3 names, but 1000? The solution is to create an array . An array can hold many values under a single name, and you can access the values by referring to an index number. There are three different kind of arrays. Numeric array – Arrays with a numeric index Associative array – Arrays with named keys
