Star Triangle

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

Pattern 2


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

Output

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

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

Pattern 5


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

Output

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">  
}  
}    
?>

Output
