Iterating arrays in PHP using foreach

The foreach loop statement in PHP offers an elegant way to iterate through arrays. PHP supports two syntaxes for iterating over associative and indexed arrays. Use the foreach($array as $value) syntax for indexed arrays and the foreach($array as $key => $value) syntax for associative arrays. In this PHP Foreach Example, we iterate over an array and print all its values. Click Execute to run the PHP Foreach Example online and see results.
