This is a PHP script that uses nested `for` loops to generate a diamond pattern. The pattern is made up of asterisk (`*`) characters. The number of asterisks per line varies, creating the shape of the diamond. The outer `for` loop is responsible for the number of lines in the pattern, while the inner `for` loops control the number of spaces and asterisks per line. The script first prints the top half of the diamond (including the middle line), then the bottom half. This script demonstrates the power of nested loops and how they can be used to create complex patterns. It's a great exercise for those learning PHP and wanting to improve their understanding of loops.
<?php
echo "<pre>";
for ($a = 1;$a <= 5;$a++)
{
for ($b = $a;$b <= 5;$b++)
{
echo " ";
}
for ($c = 1;$c < ($a * 2);$c++)
{
echo (" *");
}
echo "<br/>";
}
for ($a = 4;$a >= 1;$a--)
{
for ($b = $a;$b <= 5;$b++)
{
echo " ";
}
for ($c = 1;$c < ($a * 2);$c++)
{
echo (" *");
}
echo "<br/>";
}
echo "</pre>";
?>
