[darkfreaks]

ok so i get

 

 

 

Warning: Cannot use a scalar value as an array in /home/willowg/public_html/global.inc.php on line 74

 

Warning: Cannot use a scalar value as an array in /home/willowg/public_html/header.inc.php on line 114

 

 

those lines are:

 

 

<?php


function makepassword($string ="")

{

$letters = array("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z");

if ($string)

{

	$num = rand(10,99);

	$string .= $num;

	$x = 0;

	while ($x < 2)

	{

		$which_letter = rand(0,25);

		$string .= $letters[$which_letter];

		$x++;

	}

}

if (!$string)

{

	$x = 0;

	while ($x < 6)

	{

		$which_letter = rand(0,25);

		$string .= $letters[$which_letter];

		$x++;

	}

	$num = rand(1000,9999);

	$string .= $num;

}

return $string;//line 74    

function admin_smilies($string) //line 114

{

include "config.inc.php";

$smilies = file("$websiteURL/lists/smilies.txt");

$num_smilies = count($smilies);

$x = 0;

while ($x < $num_smilies)

{

	$array = explode(" ",$smilies[$x]);

	$array[3] = ereg_replace("\r","",$array[3]);

	$array[3] = ereg_replace("\n","",$array[3]);

	$string = eregi_replace($array[0],"<img src=../images/smilies/$array[1] height=$array[2] width=$array[3]>",$string);

	$x++;

}

return $string;

}

?>

 

 

anyone got any ideas how i would fix this ???

I think the problem has to do with you declaring a variable as one type (by virtue of assigning something to it, of course), and then trying to use it as a different type.  I think.

[darkfreaks]

so how would you go about fixing it ???

 

i think it is because i use $string in 2 functions and it just uses string over again or something.

umm, well I can't really be more specific than that without pouring over your entire code (which I'm not about to do sorry lol)

 

I mean, I'm not necessarily seeing a problem with the code that you provided, so you're probably gonna have to backtrack and see what argument you're trying to pass to your functions.

 

You just have to go through your code and make sure you didn't do anything like declare your variable somewhere else that's under the same jurisdiction as in this function (like a global variable) etc...

 

p.s.-

 

using $string in more than one function doesn't necessarily mean anything. They are both local variables that are trashed when the function breaks...but it might mean something if you have, as mentioned, a global version of it somewhere.

I made a separate post because I know you're reading:

 

How about trying a little } after that return, and before your next function.  That might possibly be it, because without that, it's like, trying to use your variable in two different ways.
