How can you add 'x' (number) to the second line on a text file with php?

[faydra92]

in a file, how can you retrieve the first and second lines, and add a variable "x" to them and save the files again?

file() will load the text file into an array.

$text = file("directory/filename.txt");

Keeping in mind that arrays start counting at 0, if you want line 40, you'd access it using $text['39']

If you want to add x to the end of the line:

$text['39'] = $text['39'] . "x";

then after you've edited the file the way you want, just implode it to a string and frwite() it. like so:

<?php
$file = 'somefile.txt';
$file_text = file($file);
$file_text[1] .= $x;//add the $x var to the end of line 2
$new_file = implode("\n",$file_text);//put a newline between each element of an array and make it a string
$fp = fopen($file,"w");//open a file for writing
fwrite($fp,"");//wipe the file (i think?)
fwrite($fp,$new_file);//write the modified text file
fclose($fp);//close the link
?>
