How to use a loop In PHP
To count all array elements in PHP using a loop, initialize a counter variable to zero. Iterate through the array elements using a loop and increment the counter for each element. The final count represents the total number of elements.
Example
<?php
// Single-dimensional array
$array = array("Geek1", "Geek2", "Geek3", "1", "2", "3");
$count = 0;
foreach ($array as $element) {
$count++;
}
echo "Count first array elements: $count \n";
// Multi-dimensional array
$array = array(
'names' => array("Geek1", "Geek2", "Geek3"),
'rank' => array('1', '2', '3')
);
// Recursive count
$count = 0;
foreach ($array as $subarray) {
foreach ($subarray as $element) {
$count++;
}
}
echo "Recursive count: $count \n";
// Normal count
echo "Normal count: " . count($array) . "\n";
?>
Output
Count first array elements: 6 Recursive count: 6 Normal count: 2
