Question

<?php
$list    = file_get_contents('sitelist.txt');
$explode = explode("http://", $list);
$i       = 1;
for ($i = 1; $i < count($explode); $i++) {
    $filename = 'tost.txt';
    $fp       = fopen($filename, "a+");
    $write    = fputs($fp, $explode[$i] . "\n");
    fclose($fp);
}
echo "ok";
?>

It’s not write or putting anything in tost.txt. what’s the wrong here ?

Answer 1

I see some issues with your code

for ($i = 1; $i < count($explode); $i++) {
    $filename = 'tost.txt';     <-------------------+
    $fp       = fopen($filename, "a+");-------------| All this should not be 
    $write    = fputs($fp, $explode[$i] . "\n");<---| in a loop
    fclose($fp); <----------------------------------+
}

All you are tying to do is the the same of this 2 lines

$list = file_get_contents('sitelist.txt');
file_put_contents('tost.txt', implode("\n", explode("http://", $list)));

Observation

Sill not sure why you have decided to use the following code

 explode("http://", $list)

This would

• Ignore new lines
• Return Invalid urls etc

You need to add your var_dump($list) and expected output if you are really going to have a working solution
