As stated above, if you want to parse the csv later with fgetcsv, you should disable the escape mechanism by setting the escape parameter to empty string. Here is what can happen if you don't:
<?php
$a = array('xyz\\', 'qwerty');
var_dump($a);
$f = fopen('test.csv', 'w');
fputcsv($f, $a);
fclose($f);
$f = fopen('test.csv', 'r');
$b = fgetcsv($f);
fclose($f);
var_dump($b);
?>
Result :
array(2) {
[0]=>
string(4) "xyz\"
[1]=>
string(6) "qwerty"
}
array(1) {
[0]=>
string(13) "xyz\",qwerty
"
}
As you can see, the output of fputcsv cannot be safely parsed by fgetcsv.
