For loops are the most complex loops in PHP. The for loop executes through a block of code a specified number of times when you know how many times the script should run ahead of time.
PHP for Loop
Syntax
for (init counter; test counter; increment counter) {
code to be executed for each iteration;
}Parameters:
- init counter: Initialize the loop counter value
- test counter: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
- increment counter: Increases the loop counter value
Example
The example below shows the numbers from 0 to 10:
<?php
for ($n = 0; $n <= 10; $n++) {
echo "The number is: $n <br>";
}
?>Example Explained
- $n = 0; - Initialize the loop vatiable ($n), and set the value to 0
- $n <= 10; - Continue the loop as long as $n is less than or equal to 10
- $n++ - Increase the loop variable value by 1 for each iteration
