Question

I am currently working an auto-content-generator script\'s sitemap. I got to know that google accept sitemap in simple text file that contains one URL per line.

so I cre

Answer 1

This is hopefully easier to understand:

$file = 'assets/sitemap/1.txt';
$url  = "http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI]."\n";

$text = file_get_contents($file);

if(strpos($text, $url) === false) {
    file_put_contents($file, $url, FILE_APPEND);
}

• Read the file contents into a string $text using file_get_contents()
• Check if $url is in the string $text using strpos()
• If $url is not in the string $text, append the $url to the file using file_put_contents()

To count the total lines, you can start using file() to load the file lines into an array. Then check if the $url is in the array using in_array():

$lines = file($file);
$count = count($lines); // count the lines

if(!in_array($url, $text)) {
    file_put_contents($file, $url, FILE_APPEND);
    $count++; // if added, add 1 to count
}
