there is a bug using fseek on previos versions of PHP8.0.1
See:
https://bugs.php.net/bug.php?id=46569
https://3v4l.org/O89dJ
I solved it with a function:
<?php
/**
* SEEK an Spl object
* There is a bug in php for seeking files
* seems solved php_version > PHP8.0.1
* See https://bugs.php.net/bug.php?id=46569
* & https://3v4l.org/O89dJ
*
* $Spl->seek() Works ok in all versions with offset 0 (first row)
* On PHP_VERSION < 8.0.1:
* - Offset 1: seek() cannot seek at row 1. It will be done manually, rewind file and reading first
row
* - Rest of Offsets: The cursor remains at next row of $Offset
*
* @param SplObject $Spl
* @param int $Offset
*/
function seek_spl($Spl, $Offset){
if (version_compare(PHP_VERSION, '8.0.1', '>=') || $Offset == 0) {
$Spl->seek($Offset);
} else {
if( $Offset == 1 ){
$Spl->rewind(); // Ensure to go at first row before exit
$Spl->fgets(); // Read line 0. Cursor remains now at line 1
} else {
$Spl->seek($Offset-1);
}
}
}?>
