My Experiments with PHP

The following program defines and initializes an array to store data and the contents are displayed with a php program.

Code:
<?php
// Defining photos as an array
$photos = array();
// Initialising the array with values
$photos['0'] = "Cat";
$photos['1'] = "Rat";
$photos['2'] = "Tiger";
$photos['3'] = "Lion";
$photos['4'] = "Bear";
$photos['5'] = "Buffalo";
$photos['6'] = "Giraffe";
//count the elements in an array and stores the value in variable number
$number = count($photos);

echo 'The number of animals in the array photos is '.$number.'<br><br>'; 
// Displaying the elements of the array separated by a line break
for ($i=0;$i<$number;$i++) {
    echo $photos[$i].'<br>';
}
