This article is aimed at giving a PHP implementation for pattern printing.
<?php // Php code to demonstrate // star pattern // Function to demonstrate // printing pattern function pypart($n) { // Outer loop to handle number // of rowsn in this case for ($i = 0; $i < $n; $i++) { // inner loop to handle // number of columns // values changing acc. // to outer loop for($j = 0; $j <= $i; $j++ ) { // Printing stars echo "* "; } // ending line after // each row echo "
"; } } // Driver Code $n = 5; pypart($n); ?> |
Output :
* * * * * * * * * * * * * * *
<?php // PHP code to demonstrate // star pattern // Function to demonstrate // printing pattern function pypart2($n) { for ($i = 1; $i <= $n; $i++) { for ($j = 1; $j <= $n; $j++) { if($j<=($n-$i)){ echo " "." "; }else { echo "* "; } } echo PHP_EOL; } } // Driver Code $n = 5; pypart2($n); ?> |
Output :

<?php // PHP code to demonstrate // star pattern // Function to demonstrate // printing pattern function triangle($n) { // number of spaces $k = 2 * $n - 2; // outer loop to handle // number of rows // n in this case for ($i = 0; $i < $n; $i++) { // inner loop to handle // number spaces // values changing acc. // to requirement for ($j = 0; $j < $k; $j++) echo " "; // decrementing k after // each loop $k = $k - 1; // inner loop to handle // number of columns // values changing acc. // to outer loop for ($j = 0; $j <= $i; $j++ ) { // printing stars echo "* "; } // ending line after // each row echo "
