fopen problem

cyb

I am an antique and I(don't ask why, its an obscure reason) can't make SQL work, so I'm storing usernames in a text file. For some reason, the fopen command is not working more than once in a loop. Please explain, and do NOT mention SQL, unless no one else can come up with another solution. Thanks in advance.

What I am doing is opening a text file, loading the first username, checking if it exist, if not create the file, if so leave it alone, and write the link. The purpose is so that a control panel will be able to add/delete users in a text file, and this php script will load them into a list of users(with the A HREF pointing to their user pages). For some reason the fopen command works only once on the first time through the loop. It will create
firstname%20lastname.htm if it does not exist but nothing else.


$doesexist4 = file_exists("teach_4.txt");
If($doesexist4 == false) {
    $teach4new = fopen("teach_4.txt", 'w');
    $blanktxt4 = "";
    fwrite($teach4new, $blanktxt4);
    fclose($teach4new);
}
$teach4 = fopen("teach_4.txt", 'r');
$teach4read = fread($teach4, 1024768);

$teachers4 = strtok($teach4read, ',');
while ($teachers4 !== false) {
	    echo "<A HREF='$teachers4.htm'>$teachers4</A><BR>";
	    $doesexistt4 = file_exists("$teachers4.htm");
	    echo "error on $doesexistt4";
	    If ($doesexistt4 == false) {
	        $teachers4new = fopen("$teachers4.htm", 'w');
	        $blanktxt = "";
	        fwrite($teachers4new, $blanktxt);
	        fclose($teachers4new);
	    }
	    $teachers4 = strtok(",");
	};

where teach4.txt equals "firstname lastname, weird teacher, extra"

the end 🙂

I notice there are errors on the other names (you didn't mention these). Possibly it's because they start with spaces.

$teachers4 = trim($teachers4);
$doesexistt4 = file_exists("$teachers4.htm");

This could be another approach:

if(file_exists('teach_4.txt'))
{
	$teachers = join('',file('teach_4.txt'));
	// $teachers = file_get_contents('teach_4.txt'); // Version for PHP4.3 or later
	$teachers = explode(',',$teachers);
	foreach($teachers as $teacher)
	{
		$teacher = trim($teacher);
		$fp = fopen($teacher.'.htm', 'a');
		fclose($fp);
	}
}

Ah yes, it's always some stupid, small mistake like *spaces_before_filenames that gets you!

Thankyou soo much, you saved my life(I think my customer would've throttled me if I couldn't get the code working). The "trim()" function worked perfectly.

Thanks again,
