The star triangle in PHP is made using for and foreach loop. There are a lot of star patterns. We’ll show some of them here.

Pattern 1

  <?php  for($i=0;$i<=5;$i++){  for($j=5-$i;$j>=1;$j–){  echo “* “;  }  echo “<br>”;  }  ?>  

Output:

PHP Star triangle 1

Pattern 2

  <?php  for($i=0;$i<=5;$i++){  for($j=1;$j<=$i;$j++){  echo “* “;  }  echo “<br>”;  }  ?>  

Output:

PHP Star triangle 2

Pattern 3

  <?php  for($i=0;$i<=5;$i++){  for($k=5;$k>=$i;$k–){  echo ”  “;  }  for($j=1;$j<=$i;$j++){  echo “*  “;  }  echo “<br>”;  }  for($i=4;$i>=1;$i–){  for($k=5;$k>=$i;$k–){  echo ”  “;  }  for($j=1;$j<=$i;$j++){  echo “*  “;  }  echo “<br>”;  }  ?>  

Output:

PHP Star triangle 3

Pattern 4

  <?php  for($i=1; $i<=5; $i++){   for($j=1; $j<=$i; $j++){   echo ‘ * ‘;   }  echo ‘<br>’;   }  for($i=5; $i>=1; $i–){   for($j=1; $j<=$i; $j++){  echo ‘ * ‘;   }   echo ‘<br>’;   }   ?>  

Output:

PHP Star triangle 4

Pattern 5

  <?php  for ($i=1; $i<=5; $i++)  {   for ($j=1; $j<=5; $j++)    {     echo ‘* ‘;    }     echo “</br>”;  }  ?>  

Output:

PHP Star triangle 5

Pattern 6

  <?php  for($i=5; $i>=1; $i–)  {  if($i%2 != 0)  {  for($j=5; $j>=$i; $j–)  {  echo “* “;  }  echo “<br>”;  }  }  for($i=2; $i<=5; $i++)  {   if($i%2 != 0)  {   for($j=5; $j>=$i; $j–)  {  echo “* “;  }  echo “<br>”;  }  }  ?>
