PHP foreach loop

foreach loop only works on arrays and is used to iterate over each key/value pair in the array.

Syntax

foreach ($array as $value) {

code to be executed;

}

Every time a loop iteration is performed, the value of the current array element will be assigned to the $value variable, and the array pointer will Move one by one until you reach the last array element.

The following example demonstrates a loop that will output the values ​​of a given array ($colors):

Example

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