WTH?? Explain

Is the password always going to be on the second line? if so you could do

$lines = file('michael.txt');

$lines = array_map('trim', $lines);

// update the second line.
$lines[1] = 'password = new_password';

// update the file.
file_put_contents('michael.txt', implode(PHP_EOL, $lines));

<?php exec("sed -i 's/hello_world/hello-world/' micheal.txt"); ?>

 

I'll admit that he wasn't being too specific, but I doubt you'd want to use sed to find the specific value and replace it like that if you don't know the value off hand.

o and how do check wich files are in a Folder.. so like:

users/[name of file].txt

and echo the values

just like doing so:

<?php
$result = mysql_query("SELECT * FROM users");
while($users = mysql_fetch_array($result))
{
  echo $users['name'];
}
?>

but then not in MYSQL.. in a folder.

You can use glob() for that

 

foreach (glob("users/*.txt") as $userfile) {
    echo "$userfile<br />";
}

one last.. this one is harder..

Lets say in that file thers something called membership:

Values are:

membership = 1

or

membership = 0

 

1 = true

0 = false.

 

how could i make it so that the value will be 1 but after 31 days the value changes to 0

Wait, do you have a file for each user?  Use a database.

 

EDIT:5000th post!

[mikelmao]

i may not use a DB... it needs to be in a file.. And Gratz dude.. 5000TH Post on my Thread.. Im Honerd =)

How can i check the value of the veriable tho?

username = michael
password = hello_world
age = 13
real_name = michael
last_name = hello_world

Veriable = age

Value of Veriable = 13

 

i dont care if its line 2.. just the value of the veriable i need to know.
