Untested, but give this a try;
<?php
$fp = fopen('/file.txt', 'r') or die("Could not open file for reading\n");
$linedata = array();
$line_num = 0;
while(!feof($fp) {
$line = fgets($fp);
i($line_num == 1) {
array_push($linedata, "My new line of text\n");
} else {
array_push($linedata, $line);
}
}
fclose($fp);
$fp2 = fopen('/target.txt', 'a+') or die("Could not open file for writing\n");
$file_body = impode("\n", $linedata);
fwrite($fp2, $file_body);
fclose($fp2);
?>
adrian_brooks, thank you. Now what do I do if [context] is not the first line of the text file but is somewhere between the file?
Active 3 days ago
Well, simply swap out the "if($line_num == 1) {" conditional with this;
if(preg_match('/\[context\
This will then fire only when it encounters that exact text match. :)
if(preg_match('/\[context\
This will then fire only when it encounters that exact text match. :)
adrian, why do you have two files; file.txt,target.txt? I am working with only one file that has the date that needs to be manipulated ( data.txt). Please let me know, thank you.

@aej1973: Please get the file that has your test data, and upload it to EE so we can show you how it works. If you don't have any test data yet, please create some.

@aej1973 - in a previous question, you had a line that started with "register => " instead of "register = " and now I see a colon used as an assignment after "ipaddress" - is this actually correct data? It seems really strange that you'd have varying formats inside the same file, which looks like a normal INI file (which could be parsed easily with the parse_ini_file() function):
http://php.net/manual/en/function.parse-ini-file.php
Also, in your previous question, you used file_get_contents() and explode() to get the file contents in an array of lines (by the way, you can use file() to do the same thing in one line), so I'm wondering why you're using a different approach now.

Hello gr8gonzo, you are right I was trying a different approach. I did not get a chance to work on it last night but will be working on this module shortly, I will keep you posted on the exact data and the outcome of my tests. Thank you for all your assistance.

$file = 'extensions.txt';
$txt = file_get_contents($file); //converts a file to a string
$Blocks = explode(PHP_EOL, $txt); //puts file in an array
$pLine="[users]";
$location=array_search($pLine,$Blocks)+1;
echo $location;
$data="exten=>this is a new line";
array_splice( $Blocks,$location , 0, $data );
$txt = implode("\n", $Blocks);
file_put_contents($file, $txt);

Looks fine to me. I would probably recommend using file() and a couple of inline values just to avoid the creation of extra variables that don't really serve another purpose:
$file = 'extensions.txt';
$blocks = file($file);
$location=array_search("[u
$data="exten=>this is a new line";
array_splice($blocks,$loca
file_put_contents($file, implode("\n", $blocks));
$file = 'extensions.txt';
$blocks = file($file);
$location=array_search("[u
$data="exten=>this is a new line";
array_splice($blocks,$loca
file_put_contents($file, implode("\n", $blocks));
