Bug #20716 fgetcsv() cannot handle multi-line input
Submitted: 2002-11-29 04:52 UTC Modified: 2002-11-30 13:13 UTC
From: edink at proventum dot net Assigned:
Status: Closed Package: Filesystem function related

fgetcsv() was able to read multi-line fields that were quoted. Here is the example of the test file:

f1;f2;f3
Test 1a;Test 1b;Test 1c
Test 2a;"Test 2b - line 1
Test 2b - line 2
Test 2b - line 3";Test 2c

We are trying to parse this file with the following code:

$f = @fopen($argv[1], "r");
if (!$f) exit("Cannot open input file.\n");

$v = array();

while ($data = fgetcsv ($f, 10000, ";"))
{
  $v[] = $data;
}

var_export($v);

Now, in PHP 4.2.3 and earlier this produces correct 3 element array. PHP 4.3.0-dev produces 5 element array because it gets confused with the multiple line input in the 2b field.
