looking for entries

[scott212]

I'm trying to read through a list of entries in a text file seperated by \r and do one thing if I've found a match and something else if I don't. Here's my code:

$masterFileOpen = fopen ("D:/APACHE/data$userListFileName", "a");
if ($masterFileOpen) { $listData = file ("D:/APACHE/data/$userListFileName");
$n = 0;
while ($n <= $listData[$n]) {
if ($listData[$n] == $fullName) {
$inUse = "TRUE";
} else {
$inUse = "FALSE";
}
$n++;
}

Here are my errors:

Notice: Undefined offset: 0 in D:\APACHE\handleForm.php on line 33

Notice: Undefined offset: 1 in D:\APACHE\handleForm.php on line 32

what are these referring to? I've been all over this section and can't find any problems. I haven't been doing this for very long so I'm probably just ill-informed.

Any suggestions?

Okay, try adding a '/' after '../data' in the fopen statement.

$masterFileOpen = fopen ("D:/APACHE/data$userListFileName", "a");

should read

$masterFileOpen = fopen ("D:/APACHE/data/$userListFileName", "a");

😃

I don't know what an Undefined offset is in this case tho.

that was a copy error when putting up here, it's actually there in the script. Is this a common way to search for matches?

Got it, here it is:

$masterFileOpen = fopen ("D:/APACHE/data/userListFileName", "a");
if ($masterFileOpen) {
$listData = file ("D:/APACHE/data/$userListFileName");
$n = 0;
while ($n < count($listData)) {
if (trim($listData[$n]) == $fullName) {
$inUse = "TRUE";
} else {
$inUse = "FALSE";
}
$n++;
}

It requires one entry in the list though. I just called it 'header'.
