How to delete multiple lines from txt using php

Question

Hello is there a way to delete multiple lines from a text file by using php code? for example text.php

<a>1</a>
<a>2</a>
<a>3</a>
<a>4</a>
<a>5</a>
<a>6</a>
<a>7</a>

i would like to delete the first 5 lines without actually using the content to delete.

Yes, just get the file and overwrite it with the data, just without the first 5 lines — Rizier123

php.net/manual/en/function.fread.php look at the example #2 and #3. Its really easy. — kaito

This should do it:

$file =  "yourfile.txt"
$lines = file( $file );
$less = array_slice($lines, 4);
file_put_contents( $file, $less );

(You can't edit the file particular, you have to overwrite it.)

EDIT: delete 3-5:

$file =  "yourfile.txt"
$lines = file( $file );
$end = array_slice($lines, 4);
array_splice($lines, 2);
$less = array_merge( $lines, $end );
file_put_contents( $file, $less );

See http://php.net/manual/en/function.array-slice.php and http://php.net/manual/en/function.array-splice.php
