what are the difference between for loop & for each loop in php

Question

What are the differences between the for loop and the foreach loop in PHP?

Answer 1

Foreach is great for iterating through arrays that use keys and values.

For example, if I had an array called 'User':

$User = array(
    'name' => 'Bob',
    'email' => '[email protected]',
    'age' => 200
);

I could iterate through that very easily and still make use of the keys:

foreach ($User as $key => $value) {
    echo $key.' is '.$value.'<br />';
}

This would print out:

name is Bob
email is [email protected]
age is 200

With for loops, it's more difficult to retain the use of the keys.

When you're using object-oriented practice in PHP, you'll find that you'll be using foreach almost entirely, with for loops only for numerical or list-based things. foreach also prevents you from having to use count($array) to find the total number of elements in the array.
