Foreach

 

In PHP, the foreach loop is used to iterate over arrays and objects. It simplifies the process of iterating through elements of an array or the properties of an object without needing to keep track of iteration indices manually. The syntax for a foreach loop in PHP is as follows:

 

 

foreach ($array as $value) {
    // Code to be executed for each element in the array
}

 

 

Here, $array is the array being iterated over, and $value is a variable that represents the value of the current element in each iteration.

 

 

Optionally, you can also include the keys along with the values using the following syntax:

 

 

foreach ($array as $key => $value) {
    // Code to be executed for each element in the array
}

 

 

In this syntax, $key represents the key of the current element, and $value represents the value of the current element.

 

 

For example:

 

 

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


Output:

 

red green blue
