The PHP FOREACH function

The FOREACH construct is easy to build, though do recall that it works only on arrays and objects. 

We’re going to start with the most basic syntax. 

foreach($array as $item) {
		$code_block;
	}

In the above syntax, the parameters are:

• $array. The array or object that you want to iterate through.
• $item. The temporary variable that will contain the current value.
• $code_block. The code that you want to run each time.

FOREACH is a little unique because it involves a temporary variable. Each item in the array becomes the temporary variable for the scope of the code block. Within the FOREACH statement, you’ll use that temporary variable name to refer to the current value. The current value will always hold the current internal array pointer.
