Please explain the foreach loop.

Pretend we have ten horses in a stable, and we want to vaccinate the horses with something. In such cases you may say, For each (horse) in the stable Vaccinate (horse) Here, you say "horse", but actually, which horse you referred to, will be different each time. It's not like you would vaccinate a horse twice, or worse ten times (the count of horses). You can think of the stable as an array, and the horses as the elements of the array (the content of the array). Hth, cmiiw

The foreach construct provides an easy way to iterate over arrays. foreach works only on arrays and objects, and will issue an error when you try to use it on a variable with a different data type or an uninitialized variable. There are two syntaxes: foreach (array_expression as $value) statement foreach (array_expression as $key => $value) statement

forEach can be used for adding property to an array of objects too https://code.sololearn.com/Wu1u667O26li/?ref=app
