The 'as' operator in PHP

Question

In PHP, what does the "how" operator do? For instance,

foreach ( $this->Example as $Example )

Thank.

Answer 1

Take an example:

foreach ($array as $value) {}

It means

for each item (of $array) defined as $value...

In other words, this means that the elements of the array will be extracted inside the loop as $value. Note that you can also specify this syntax:

foreach ($array as $key => $value) {}

In both cases, vars $keyand $valuewill exist inside foreachand will correspond to the "current" element of the array.
