[RESOLVED] While loop, returning error part when it should not

[jerry_louise]

I have made a while loop to take the current page and if it matches a directory it will return that directories contents or if the value is null will return the index or if the page is gibberish it should return a the 404.htm error page.
For the most part this works expect the 404.htm page is always returned, sometimes twice.

/* 
    The page Location. 
*/ 
$page = explode('/', $_GET['page']); 

/* 
    Load the modules based on page location. 
*/ 
$i = 0; 
/* Opens the modules directory */ 
$modulesDirectory = opendir("../application/modules/"); 

/* Gets the modules name based on the directory name for each module. */ 
while ($moduleName = readdir($modulesDirectory))  

{  

    if ($moduleName!= "." && $moduleName!= "..")  

    {  

        if ($page[0] == $moduleName) 
        { 
            /* If the current page matches a module name, return that module. */ 
            include ("../application/modules/".$moduleName."/".$moduleName.".php"); 
        } 
    }  

    else if ($page[0] == '' && $i == 0) 
    { 
        /* If the current page is the / then return the bootstrap. */ 
        include ("../application/modules/example_module/example_module.php"); 
        $i++; 
    } 
    else if ($page[0] != $moduleName) 
    { 
        /* If the current page is not found in the modules return page not found. */ 
        include ("../html/errors/404.htm"); 
    } 
}  

closedir($modulesDirectory);
