Foreach As Key Value

Loop based on an expression.

foreach( <expression> as <key> => <value> )
{
    statements
    ...
}

An expression needs to be an array for this loop to happen.

The variable to place the key in most common as a $variable.

The variable to place the value in most common as a $variable.

Foreach...As..Key..Value statements may be nested.

Here we cycle through binary data :

$var = array(
		"One" => 100,
		"Two" => 200,
		"Three" => 300
		);
 
Foreach ($var as $key => $value)
{
	println( "Key '$key' | Value '$value'" );
}

A reverse foreach

$var = array(
		"One" => 100,
		"Two" => 200,
		"Three" => 300
		);
 
println( "Key '$key' | Value '$value'" ) Foreach ($var as $key => $value);

-If you wish to edit an array as you loop through it check out [[Core Function Each|Each( <array> )]] command see its examples one of them should tell you how to do this.
