SplFileObject¶
SplFileObject is an SPL class that offers an object-oriented interface for reading and writing files. It extends SplFileInfo and implements SeekableIterator, allowing line-by-line iteration over a file with a foreach loop.
SplFileObject supports reading modes r and r+, writing modes w and a, and CSV parsing via the setFlags() method combined with the READ_CSV flag.
It is a convenient alternative to the procedural fopen()/fgets()/fclose() trio when an object-oriented approach is preferred.
<?php
$file = new SplFileObject('data.txt', 'r');
$file->setFlags(SplFileObject::DROP_NEW_LINE);
foreach ($file as $line) {
echo $line . PHP_EOL;
}
?>
