[[SOLVED] Error with session]

Hi, im building a forum system, i was using cookies too log people in, but obviously some of them want too be able to be logged out when they close their browser, so i thought I'd integrate it with sessions, but on the second page of being logged in the session expires.

 

Do i need to redeclare the session?

[PHP Availability Calendar]

Look through the php scripts, i found one on this site but i can't remember if it worked from a MySQL database, maybe you should try downloading SMF, they have a calendar system.

[simple question]

A variable is always secure.. And as far as i know the only way for people to be able to get variables from you site is by using cURL.

 

Just make sure that whenever you use a form action of post, set your variable as $_POST['variable'] etc.

[Windows PHP connect into LINUX server]

soz i just realised you wanted to let it be editable... just use the fopen function

<?php 
$file = 'path to php.ini' ; 
$content = file_get_contents($file); 
//edit some of this
echo "
<form action='file update.php'>
<textarea name='new_content'>$content</texarea><br />
<input type='submit' value='submit' />
</form>
";
?>

 

now you need to update the file contents to the textarea variable

 

<?php
$file = 'path to php.ini' ; 
fopen ($file);
fwrite($file, $_POST[new_content]);
fcolse($file);
?>

[Windows PHP connect into LINUX server]

cant you just use the windows server to connect to the linux server by finding the path of the .ini file

eg.

$lines = file('path to php.ini');
foreach ($lines as $num => $line) {
echo "Line-($num): $line<br />";
}

 

or just use the include function
