Summary<\/strong>: in this tutorial, you will learn how to use PHP foreach<\/code> statement to loop over elements of an array.<\/p>\n\n\n\n

Introduction to the PHP foreach statement #<\/a><\/h2>\n\n\n\n

PHP provides you with the foreach<\/code> statement that allows you to iterate over elements of an array<\/a>, either an indexed array<\/a> or an associative array<\/a>.<\/p>\n\n\n\n

The foreach<\/code> statement iterates over all elements in an array, one at a time. It starts with the first element and ends with the last one. Therefore, you don’t need to know the number of elements in an array upfront.<\/p>\n\n\n\n

The following flowchart illustrates how the foreach<\/code> statement works:<\/p>\n\n\n

PHP foreach with indexed arrays #<\/a><\/h2>\n\n\n\n

To iterate over all elements of an indexed array, you use the following syntax:<\/p>\n\n\n

<?php<\/span>\n\nforeach<\/span> ($array_name as<\/span> $element) {\n    \/\/ process element here<\/span>\n}<\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
When PHP encounters a foreach<\/code> statement, it assigns the first element of the array to the variable following the as<\/code> keyword ($element<\/code>).<\/p>\n\n\n\n
In each iteration, PHP assigns the next array element to the $element<\/code> variable. If PHP reaches the last element, the loop ends.<\/p>\n\n\n\n
The following example uses the foreach<\/code> statement to display elements of the $colors<\/code> array:<\/p>\n\n\n
<?php<\/span>\n\n$colors = ['red'<\/span>, 'green'<\/span>, 'blue'<\/span>];\n\nforeach<\/span> ($colors as<\/span> $color) {\n\techo<\/span> $color . '<br>'<\/span>;\n}<\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
red\ngreen\nblue<\/code><\/span>Code language:<\/span> plaintext<\/span> (<\/span>plaintext<\/span>)<\/span><\/small><\/pre>\n\n\n
PHP foreach with an associative array #<\/a><\/h2>\n\n\n\n
To iterate over elements of an associative array<\/a>, you use the following syntax:<\/p>\n\n\n
<?php<\/span>\nforeach<\/span> ($array_name as<\/span> $key => $value) {\n   \/\/process element here;<\/span>\n}<\/span><\/code><\/span>Code language:<\/span> HTML, XML<\/span> (<\/span>xml<\/span>)<\/span><\/small><\/pre>\n\n\n
When PHP encounters the foreach<\/code> statement, it accesses the first element and assigns:<\/p>\n\n\n\n
