I am trying to make something like this:

                  1

                  23

                456

            7891011

          1213141516

            17181920

              212223

                2425

                  26

 

 

But i have managed what I've shown above. Anyone have any help on this?

Okay, I figured it out, well kind of, but I need to reduce the amount of line have. Any ideas?

[AyKay47]

you can condense that into one for loop with if conditionals..

 

for($a=1; $a <= 26; $a++){
   if($a == 1)
      echo $a ."<br />".;
   if($a == 2 || $ == 3)
      echo $a;
   if($a == 4)
      echo $a ."<br />".;
}

 

won't get an award on its looks... but will use one for loop instead of 9

[mayman212]

nope that didnt work mate>

[AyKay47]

for($a = 1; $a <= 26; $a++){
   if($a == 1)
      echo $a ."<br />";
   if($a == 2 || $ == 3)
      echo $a;
   if($a == 4)
      echo $a ."<br />";
}

 

concatenation error.. it will work

[mayman212]

 

( ! ) Parse error: syntax error, unexpected T_IS_EQUAL, expecting T_VARIABLE or '$' in C:\wamp\www\p1\m2.php on line 10

 

that is what's showing.

[mayman212]

anyone have any more clues?

[AyKay47]

where is line ten

[mayman212]

Sorry?

[AyKay47]

your error is on line 10.. show us line 10

This is still the code I am using, the one you gave earlier came up with the unexpected error.

[mayman212]

Anyone?

[AyKay47]

using the code i provided.. show me line 10.

<table>
<tr>
<td align="center">

$b = 1;
for($a = 1; $a <= 26; $a++){
   if($a == 1)
      echo $a ."<br />";
   if($a == 2 || $ == 3)
      echo $a;
   if($a == 4)
      echo $a ."<br />";
}
?>
</td>

"$" is not a valid variable.

[Drummin]

Maybe a little primitive for the coding gurus, but it duplicates the example you gave.

<table>
<tr>
<td align="center">
<?PHP
$a=1; 
$b=1;
$d=16; 
$c=1;//line limit
while ($b<=$c && $a<=$d){
while ($b<=$c && $a<=$d){
	echo $a;
$a++;
$b++;
}
        echo "<br>";
IF ($c<3){
$c++;
}
ELSE{
$c=5;
} 
$b=1;
}
//Start Down  
$b=4;
$c=1;
$e=26;
while ($c<=$b && $a<=$e){
while ($c<=$b && $a<=$e){
	echo $a;
$a++;
$c++;
   }
        echo "<br>";
$b--;
$c=1; 
}
?>
</td>

Thanks for that. But has anyone got something with less lines?

[mayman212]

I need something with a little less lines, the code I have right now is a little too long. Anyone have any suggestions?
