Loop and Variable Interpolation in PHP
Variable interpolation into strings is also convenient to perform in loops:
<?php
for ($i = 1; $i <= 5; $i++) {
echo "xxx $i yyy";
}
?>
Simplify the following code:
<?php
for ($i = 1; $i <= 10; $i++) {
for ($j = 1; $j <= 10; $j++) {
echo 'nums: ' . $i . ' ' . $j . '<br>';
}
}
?>
