![]() But making them $key and $value helps to keep track of what they mean. You can define two parameter inside foreach separated through as keyword. ![]() You could replace that with as $foo => $bar and it would work fine as long as you changed the variable references inside the loop block to the new variables, $foo and $bar. Foreach Loop in PHP The foreach Loop is used to display the value of array. ![]() Since you don't use the $key variable inside your loop block, adding it or removing it doesn't change the output of the loop, but it's best to include the key-value pair to show that it's an associative array.Īlso note that the as $key => $value designation is arbitrary. But foreach is not creating the array - commands within the foreach loop build the array. So for our example array above, the foreach loop would reach the first key-value pair, and if you specified as $key => $value, it would store 'key1' in the $key variable and 'value1' in the $value variable. php: display key and value for each element of associative array. Iterate through array and get key and value. In the PHP code: $featured is the associative array being looped through, and as $key => $value means that each time the loop runs and selects a key-value pair from the array, it stores the key in the local $key variable to use inside the loop block and the value in the local $value variable. PHP: Get the key from an array in a foreach loop. In PHP, associative arrays look like this: $featured = array('key1' => 'value1', 'key2' => 'value2', etc.) I have a multiple array and want to echo each one in a specific format, and in groups. The first one only uses integer comparison and increasing while the last one has to create an (possibly big) array and then extract each element by moving the internal array cursor and checking whether the end is reached.

Traditional for loop is faster than foreach + range. ![]() Ask Question Asked 10 years, 11 months ago. Well, the $key => $value in the foreach loop refers to the key-value pairs in associative arrays, where the key serves as the index to determine the value instead of a number like 0,1,2. foreach with arraychunk in php and with multiple arrays. ![]()
