Anyone know how I can delete the first 9 lines in a text file?
Thanks.

<?php
$path = '/path/to/file.txt';

$file = file($path) or exit('could not read file');
foreach ($file as $key => $value)
{
	if ($key <= 8) {unset($file[$key]);}
	else {break;}
}
$file = implode("\n", $file);

$handle = fopen($path, 'w') or exit('could not read file');
$bytes = fwrite($handle, $file) or exit('could not write to file');
echo $bytes . ' written to ' . $path;
?>

Perfect, Thank you.

Just now getting back to this... Anyway, the script is creating a blank line between every line in the text file. It's doing the delete like it's supposed to, so that's good, but it's leaving some white space. Anyone see why?

I've tried some different ereg_replace stuff on the $file variable but I'm getting nowhere fast!

Example

1

2

3

Instead of:

1
2
3

Thanks

Well, for there to be "lines" at all in the file in the first place, then there must already be \n characters on the end of each of them. When the file is read into an array with the file() function, it does not strip those newline characters. Therefore, using the "\n" character when imploding them back to the file is adding a superfluous newline.

Use this instead:

$file = implode("", $file);
