Lecture 27: Foreach Loop
The Foreach Loop! This loop is a very popular loop, and is used extensively in database-driven websites. The purpose of a Foreach Loop is to "loop through each key/value pair in an array" (w3schools).
The syntax looks like so:
foreach ($array as $value) {
// execute code
}
Basically, here's what happens during each loop iteration:
Assign value of current array element to $value
$value is echoed on the screen
The array pointer then moves to the next element within the array
Repeat from beginning until final array element
Let's use a real-world example of how to use a Foreach Loop:
// We need to create an array
// Let's resurrect our array of moustaches
$moustaches = array("Handlebar", "Salvador Dali", "Fu Manchu");
// Loop through the $moustaches array
foreach ($moustaches as $moustache) {
// Output each individual value
echo "I love the $moustache. ";
}
If coded correctly, this should echo the three moustaches in the array on your screen.
