PHP for Loop

You can use a for loop if you have already determined in advance how many times the script has been run.

Grammar

for (init counter; test counter; increment counter) {  code to be executed;}

Parameters:

• Init counter: Initialize the value of the loop counter
• Test counter:: Evaluate each iteration of the loop. If the value is TRUE, the loop continues. If it has a value of FALSE, the loop ends.
• Increment counter: Increase the value of the loop counter

The following example shows a number from 0 to 10:

<?php for ($x =0; $x <=10; $x + +) {  echo "number is: $x <br>";}?>

PHP foreach Loop

The Foreach loop applies only to arrays and is used to iterate through each key/value pair in the array.

Grammar

foreach ($array as $value) {  code to is executed;}

For each iteration of the loop, the value of the current array element is assigned to the $value variable, and the array pointer moves one at a time until the last array element is reached.

The following example shows a loop that outputs the value of a given array ($colors):

Instance

<?php $colors = Array ("Red", "green", "blue", "yellow"); foreach ($colors as $value) {  echo "$value <br>";}? >
