范例
SplFileObject::getCsvControl() example
<?php $file = new SplFileObject("data.txt"); print_r($file->getCsvControl()); ?>
以上例程的输出类似于:
Array ( [0] => , [1] => " [2] => \ )

- SplFileObject::setCsvControl() Set the delimiter, enclosure and escape character for CSV
- SplFileObject::fgetcsv() Gets line from file and parse as CSV fields
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) """ }
