While loop?

Spear_Chucka

I am having a problem with this while loop.


<?php
$dir = "data";
$dp = opendir($dir);

while(false !== ($file = readdir($dp))){
	if($file != "." && $file != ".."){
		if($appfile = 'apr_' . $file){
			echo "<a href=\"finsmplreq.php?fid=$file\">file approved</a><br>";
		}else{
			echo "<a href=\"finsmplreq.php?fid=$file\">file</a><br>";
		}
	}
}



?>

The while loop displays the file approved link twice. I think it's just a novice mistake but I don't want it to display the file if the file has a corresponding aproved file. Which is in the format of apr_$file. I think I should also specify that I do want to display the file approved link with the original file as the link.

Am I close or am I a moron?

while(false !== ($file = readdir($dp))){

well, from what i can tell.. its supposed to stop if the file is not open for reading or something... if u only want it to run once on that file.. why not do a simple inrement while loop?

loopcounter = 0
do
{
if($file != "." && $file != ".."){ 
        if($appfile = 'apr_' . $file){ 
            echo "<a href=\"finsmplreq.php?fid=$file\">file approved</a><br>"; 
        }else{ 
            echo "<a href=\"finsmplreq.php?fid=$file\">file</a><br>"; 
        } 
    } 
    $loopcounter++;
} while ($loopcounter = 0);

that will run it once, and u'll have to add other vars, or whatever...

another idea.. what is your first while loop returning on the second run through?

while(false !== ($file = readdir($dp))){

is it returning false or what...

u might try

$file != readdir($dp)

i've never really played much with file functions but, i'm assuming u'r writing that wrong just by looking at it.

I know it's got to be some trival thing.

The

while(false != ($file = readdir($dp))){

was actually taken from the www.php.net site. It's the format that it says to use.

The site says that is the correct way to loop through a directory.... I am still relatively green in PHP.

If I do the do while loop will that display multiple entries? Such as (link)file for files not approved and (link)file approved for files that are?

what are u trying to do exactly? check if a file exhists? or what... maybe then i'd have a better idea of how to do this..
