Note that this function does not magically guess the CSV control from a given file, rather it returns what has been priorly set with SplFileObject::setCsvControl().

SplFileObject::getCsvControl — Get the delimiter and enclosure character for CSV
Gets the delimiter and enclosure character used for parsing CSV fields.
This function has no parameters.
Returns an indexed array containing the delimiter and enclosure character.
Example #1 SplFileObject::getCsvControl() example
<?php
$file = new SplFileObject("data.txt");
print_r($file->getCsvControl());
?>
The above example will output something similar to:
Array
(
[0] => ,
[1] => "
)
Note that this function does not magically guess the CSV control from a given file, rather it returns what has been priorly set with SplFileObject::setCsvControl().
Seems that this function always returns the same delimiter.
<?php
file_put_contents("A;B;C;D\n0;0;0;0", "test.txt");
$file = new SplFileObject("test.txt");
var_dump($file->getCsvControl());
?>
array(2) {
[0]=>
string(1) ","
[1]=>
string(1) """
}
