Simple Code needs fixing

[Scottmandoo]

Couls someone help me fix this code, I think I need to put in a function and a return but i'm not quite sure.
All the code does is return the value # for everything even letters

$letter       = ucfirst($_POST['tut_name']);
$letter2      = $letter{0};
 
    if($letter2 = 1) 
        { 
        $letter3 = '#';  
        } 
        else if ($letter2 = 2)   
            { 
            $letter3 = '#'; 
            } 
			else if ($letter2 = 3)   
            	{ 
            	$letter3 = '#'; 
            	}
				else if ($letter2 = 4)   
            		{ 
            		$letter3 = '#'; 
            		}
					else if ($letter2 = 5)   
            			{ 
            			$letter3 = '#'; 
            			}
						else if ($letter2 = 6)   
            				{ 
            				$letter3 = '#'; 
            				}
							else if ($letter2 = 7)   
            					{ 
            					$letter3 = '#'; 
            					}
								else if ($letter2 = 8)   
            						{ 
            						$letter3 = '#'; 
            						}
									else if ($letter2 = 9)   
            							{ 
            							$letter3 = '#'; 
            							}
										else if ($letter2 = 0)   
            								{ 
            								$letter3 = '#'; 
            								}
					else $letter3 = $letter{0};

I'm lost
Are you saying that your code currently returns # signs for all the text entered or are you saying that you would like it to return the # for your letters?

What are you wanting it to do, and what is it doing?

ok what i want my code to do is

If $letter2 = a number 1, 2, 3 etc. it sets $letter3 to '#'
If $letter2 = a letter it sets $letter3 to $letter2 so it pretty much stays the same

is that what you wanted to know?

And what my code currently does is just set $letter3 to '#' for letters and numbers

You can use is_int
Eg.

if(is_int($letter2)){
$letter3="#";
} else {
 $letter3=$letter2;
}

[Scottmandoo]

Thanks that works perfect!!!

[nav33n]

You are welcome :)

[Scottmandoo]

sorry, just tried testing again and it doesnt make the numbers change to the # symbol

[nav33n]

umm.. Can you post your code ?

What are you doing btw ? $letter2 will have the first character of $letter. And, it works for me!
$letter2 = $letter{0};

Just uploading some files :)

But when I upload a file starting with 3, it inserts $letter3 as 3 not the # symbol

[nav33n]

Use is_numeric instead of is_int :) !

[Scottmandoo]

Yep that works now, thanks again :)
