fgetcsv returning NULL in PHP 4

Question

One of our systems is running on PHP 4 and no I can't change that.

The fgetcsv function seems to return null no matter what file I upload.

Very simply put:

$handle = fopen($file,"r");
var_dump(fgetcsv($handle));
fclose($handle);

This will print out "NULL".

Doing var_dump on the $handle object does give me a resource:

resource(33) of type (stream)

But I just get NULL when using fgetcsv

I can get the contents of the file using file_get_contents, but then it's more awkawrd to parse it as a csv.

As I say, I can't really do anything about it being on PHP 4. Does anyone know what might be causing this, or shall I find another way?

Thanks

Yeah, dunno, that's all I got heh. Maybe PHP4 can't `var_dump()` something that's not actually a var? Assign the return value to a var first? — Alex Howansky, Aug 14 '18 at 14:11
4.4.9. I'm trying to do it with file_get_contents at the moment, but it seems even running the trim() function on some strings is too much for the server, times out after 60 seconds. Not quite sure why its struggling so much to trim some whitespace — CMR, Aug 14 '18 at 14:22

Your original issue may be related to temporary uploaded file usage.
Try to open it after move_uploaded_file

Also, fseek($handle, 0) can help theoretically, because it was read already anywhere.

I can get the contents of the file using file_get_contents

You can try to use tmpfile then:

$csv = file_get_contents($file);
$temp = tmpfile();
fwrite($temp, $csv);
fseek($temp, 0); // prepare for read at start
$data = fgetcsv($temp);
fclose($temp); // file autoremoved here

`str_getcsv()` is not available in PHP4. – Alex Howansky Aug 14 '18 at 14:16
Ooops) Didn't know that – vp_arth Aug 14 '18 at 14:20
What issue is there with "temporary uploaded file usage"? Manual, specs, citations? – deceze Aug 14 '18 at 14:31

Aha, that seems to have worked, although i had to add in a length parameter to fgetcsv(). Thjanks – CMR Aug 14 '18 at 14:32
