How to print a triangular pattern in php

March 18, 2016

We can print this pattern in php. For this we need Variables and ‘for’ loops. First we have Variables in which Symbols are passing as a string to print pattern. First ‘for’ loop is used for number of row and second & third ‘for’ loop is used for numbers in a row. ‘if’ condition is used to print empty space and ‘elseif’ condition used to print symbol.


<?php
$p="|";
$q="\\";
$r=" _ ";
for($a=1; $a<=6; $a++){
  for($b=$a; $b<=$a; $b++){
    echo $p;
      for($c=1; $c<=$a-1; $c++){
	if($a <= 5){
	  echo " &nbsp ";
	}
	elseif($a == 6 && $c<=$a/2){
	  echo $r;
	}
  } 
  echo $q; 
  }
  echo "<br>";
}
?>
