Using php print pattern

This is not new concept, you need to follow same concept like C programming to print number pattern in php.

every time on interview ask question print pattern. this is important note please keep it.
Output :
Code :

<?php for($a=1; $a<=5; $a++)
{
 for($b=$a; $b>=1; $b--)
{
echo "$b";
}
echo "<br>";
} ?>

Now simple print one column then only one for loop use to print pattern 

This is not new concept, you need to follow same concept like C programming to print star pattern or triangle of star.

Output :

Code :

<?php for ($row = 1; $row <= 5; $row++)
{
 echo "* </br>";
} ?>

print * in square size as following manner and please follow following code :

Code :

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

PHP start pattern of trangle as output and code here :

Output :

Code :

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

as above example print pattern as mirror as follow :

Output :

Code :

<?php 

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

New pattern of printing patter as following :

Output :

Code :

<?php 
for($a=5; $a>=1; $a--)
{
if($a%2 != 0)
{
for($b=5; $b>=$a; $b--)
{
echo "* ";
}
echo "<br>";
}
}
for($a=2; $a<=5; $a++)
{
 if($a%2 != 0)
{
 for($b=5; $b>=$a; $b--)
{
echo "* ";
}
echo "<br>";
}
}
 ?>

Following pattern of trangle print as refer following steps :

Output :

Code :

<?php 
for($i=0;$i<=9;$i++){

  for ($d=10-$i; $d > 0; $d--)  {

    echo    "&nbsp;&nbsp;";
  }
  for($j=1;$j<=$i;$j++){

    echo "&nbsp;".$i."&nbsp;";
 }

 echo "<br>";

} 
 ?>

please follow the following code to print pattern : 

Output :

Code :

<?php 
for($i=0;$i<=7;$i++){
for($j=1;$j<=$i;$j++){
echo $i;
}
echo "<br>";
} 
 ?>

print one one at row and column as following :

Output :

Code :

<?php 
for($i=0;$i<=7;$i++){
for($j=1;$j<=$i;$j++){
echo "1";
}
echo "<br>";
}
 ?>

HOW TO MAKE A NUMERIC POLYGON SHOWS ONLY ONE AND A PLUS SIGN WITH NUMBERS.

Output :

Code :

<?php 
$m=1; $n=9; $z=9;
for($i=1; $i<=$n; $i++){
 for($j=$i; $j<=$n-1; $j++){
   echo "&nbsp;&nbsp;&nbsp;";
   }
 for($k=1; $k<=$m; $k++){
  if($k==$m  || $k==1 || $i==$n){
     echo $k ."&nbsp";
     }
   else{
    echo "&nbsp;&nbsp;&nbsp;";
    }
  }
 for($c=$m; $c>1; $c--){
   if($c-1 == 1 || $m==$n){
     echo $c-1 ."&nbsp";
     }
   else{
     echo "&nbsp;&nbsp;&nbsp;";
     }
   }
   echo "<br>";
   $m++;
}
for($i=1; $i<=$n; $i++){
 for($j=1; $j<=$i; $j++){
   echo "&nbsp;&nbsp;&nbsp;";
   }
 for($k=1; $k<$z; $k++){
   if($k==1 || $k==$z-1){
     echo $k ."&nbsp";
     }
   else{
    echo "&nbsp;&nbsp;&nbsp;";
    }
  }
 for($c=$z-2; $c>=1; $c--){
   if($c==1){
     echo $c ."&nbsp";
     }
   else{
     echo "&nbsp;&nbsp;&nbsp;";
     }
  }
  echo "<br>";
  $z--;
}
 ?>

Make start polygon using php :

Output :

Code :

<?php 
 $m=1; $n=5;
for($i=1; $i<=5; $i++) {
    for($j=$i; $j<=4; $j++) {
        echo "&nbsp;&nbsp;";
    }
    for($k=1; $k<=$m; $k++)  {
        echo "*";
    }
    for($c=$m; $c>1; $c--) {
        echo "*";
    }
    echo "<br>";
    $m++;
}
 
for($i=1; $i<=5; $i++) {
    for($j=$i; $j>=1; $j--) {
        echo "&nbsp;&nbsp;";
    }
    for($k=$n; $k>1; $k--) {
        echo "*";
    }
    for($c=$n-1; $c>1; $c--) {
        echo "*";
    }
    echo "<br>";
    $n--;
} 
 ?>

I hope that my code and pattern you like and enjoy my code, if you like my code please share and comment,

thanks
