/*

// mode: 'a' - Open for writing only. Place the file pointer at the end of the file. 

$f = fopen("e:/datefile.txt", "a") or die("Error open file!");
$txt = "\r\nIs Popular";
fwrite($f, $txt);
fclose($f);

/*
int file_put_contents ( string $filename , mixed $data [, int $flags = 0 
                                                       [, resource $context ]] )
*/

// FILE_APPEND - append the content to the end of the file
// LOCK_EX - prevent anyone else writing to the file at the same time
// The file_put_contents() function is the same as calling fopen(), fwrite() and fclose() 

file_put_contents("e:/test.txt", " New Text", FILE_APPEND | LOCK_EX);

    
/*
run:

$file = "d:\data.txt";
$content = file_get_contents($file);

$content .= "\r\n<?php\r\n";
$content .= "function f(){}\r\n";
$content .= "?>\r\n";

file_put_contents($file, $content);

/*
run: 

data.txt:
---------
<!doctype html>
<html>
<head>

<?php
function f(){}
?>
