URGENT: PHP QUERY
I asked a PHP related question and get a great reply the other day from someone here.
(Thanks again : )
I've tested the codes on my own server and it worked perfectly.
Here is the code. (Reads data from text file, info.txt and displays the text on a page)
--------------------------
<?php
//
// This is looking for 1 parameter and it supplies the
// name of a file to display on the site.
//
$txtfile = $_GET['Id'] . '.txt';
if ($txtfile <> "null") {
$Open = fopen ($txtfile, "r");
if ($Open) {
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
print ("$GetLine[0]<br>");
}
while ($n++ < 15) {
print ("<br>");
}
fclose ($Open);
} else {
print ("Error opening event file.");
}
}
?>
--------------------------
The file is called as such: http://www.beyondresearch.sg/notice_board.php?Id=info
Problem is with this new domain host is that somehow thier PHP engine cannot seem to read the codes and process them properly and I get this error message:
Error opening event file.
So im back to square one again. I have notified this domain host and they tell me to check on the php version requirement and whether will this php script works on a Windows server running php.
Would any kind fellow here know what kind of PHP requirements the server would need and if my code is suitable? I am not really a programmer and have no idea where to find the answer to this but here. Any help would be much appreciated. Thank you all.

u can put it after you check for null and before u do fopen
if ($txtfile <> "null") {
if file_exists($txtfile)) {
$Open = fopen ($txtfile, "r");
if ($Open) {
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
Print ("$GetLine[0]<br>");
}
while ($n++ < 15) {
Print ("<br>");
}
fclose ($Open);
} else {
Print ("Error opening event file.");
}
} else {
Print ("File not found");
}
}
suggest u print the name of the txtfile in your error messages
I think this will work
print ("File $txtfile not found");
if ($txtfile <> "null") {
if file_exists($txtfile)) {
$Open = fopen ($txtfile, "r");
if ($Open) {
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
Print ("$GetLine[0]<br>");
}
while ($n++ < 15) {
Print ("<br>");
}
fclose ($Open);
} else {
Print ("Error opening event file.");
}
} else {
Print ("File not found");
}
}

I think this will work
print ("File $txtfile not found");
is_readable returns TRUE if the file or directory specified by filename exists and is readable.
file_exists returns TRUE if the file or directory specified by filename exists; FALSE otherwise
so I guess is_readable is also a valid option
try both (change file_exists to is_readable), see what happens

I've tried all that.
Now instead of the the error message displaying.
The page comes out blank. : ( What should i do?

does the textfile actuall contain anything? add some diagnostics
e.g.
if ($Open) {
Print "HELLO - START READING FILE<br>");
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
Print ("READLINE HERE -- $GetLine[0]<br>");
}
while ($n++ < 15) {
Print ("<br>");
}
Print "BYE - DONE READING FILE<br>");
fclose ($Open);
e.g.
if ($Open) {
Print "HELLO - START READING FILE<br>");
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
Print ("READLINE HERE -- $GetLine[0]<br>");
}
while ($n++ < 15) {
Print ("<br>");
}
Print "BYE - DONE READING FILE<br>");
fclose ($Open);
oops type in print statement
did u spot it?
if ($Open) {
Print ("HELLO - START READING FILE<br>");
$data = file ($txtfile);
for ($n = 0; $n < count($data); $n++) {
$GetLine = explode("\t",$data[$n]);
Print ("READLINE HERE -- $GetLine[0]<br>");
}
while ($n++ < 15) {
Print ("<br>");
}
Print ("BYE - DONE READING FILE<br>");
fclose ($Open);
missing open bracket in print statement doh!

i must be some server problem.

if u not getting anything at all, I wonder if there is a problem with the PHP?
At least before u was getting a page to appear with error message
You can prove if this is the case, if u revert back to original code that u had working
If that is the case then do you have any tools which compiles PHP? It will help identify any possible errors with the new code

I will contact the host. See what their input on the case is.
If i dont get a solution in 2 days or so I'll give you the full 500 points.
Either way you have been great. Superb. Thanks rockiroads.

no probs. I would like u to revert back to what u had though, so at least the page is coming up
perhaps is_readable or file_exists is not supported, hence the use of the compiler
You would have to compile on the host, dont know if that would be possible
Its more important to get u going. Have u thought of posting a quick 20ptr question on the PHP section? Create a question with a link to this question. Hopefully someone may be able to offer more help.
