Loops
Prerequisites: Match expressions
PHP has three loop constructs: for, while, and foreach (the one
you'll use most for arrays).
for ($i = 0; $i < 5; $i++) {
echo $i;
}
$i = 0;
while ($i < 5) {
echo $i;
$i++;
}
foreach (['a', 'b', 'c'] as $letter) {
echo $letter;
}
Practice
Print the numbers 1 through 5 using a for loop.
Show solution
for ($i = 1; $i <= 5; $i++) {
echo $i;
}
