Edit a specific line of a file???

[WebNinja]

Is there a way to edit a certain line in a file with PHP?

Maybe use fopen() and insert new POST data into, say, line 5 replacing what's there?

Maybe this:

PHP: Select all

// put contents of file into $file forehand
$lines = explode("\n",$file);
$lines[4] = "new line 5"; //index is zero based so 4 is actually line 5
$file = implode("\n", $lines);
//write $file to the file

Like this?

PHP: Select all

<?php
$file = fopen("template/templateHeader.inc", "r");


$lines = explode("\n",$file);
$lines[4] = "new line 5";
$File = implode("\n", $lines);

fputs($file, "$file");
fclose($file);
?>

This should work:
<font color="#000000">

PHP: Select all

<?php
$filehandle = fopen("template/templateHeader.inc", "r");
$file = fread($filehandle);
$lines = explode("\n",$file);
$lines[4] = "new line 5";
$file = implode("\n", $lines);

fputs($file, "$file");
fclose($file);
?>

Shouldn't it be \r\n instead of just \n? Just \n has never worked for me.

Depends what OS you are on.
