what is foreach code example

Example 1: php loop through array

$clothes = array("hat","shoe","shirt");
foreach ($clothes as $item) {
	echo $item;
}

Example 2: foreach jas

const array1 = ['a', 'b', 'c'];

array1.forEach(element => console.log(element));

Example 3: forEach

const arraySparse = [1,3,,7]
let numCallbackRuns = 0

arraySparse.forEach((element) => {
  console.log(element)
  numCallbackRuns++
})

console.log("numCallbackRuns: ", numCallbackRuns)

// 1
// 3
// 7
// numCallbackRuns: 3
// comment: as you can see the missing value between 3 and 7 didn't invoke callback function.

Example 4: php loop through array

foreach (array_expression as $value)
    statement
foreach (array_expression as $key => $value)
    statement
