Languages :: PHP :: Display a session file
By: FiatLink Belgium  Date: 20/03/2003 00:00:00  English French  Points: 125 Status: Answered
Quality : Excellent
In the development of my application, I have created a cool on/off function display for the administrative users of the site to be able to view detailed debug information in an effort to assist in the issue resolution. Having said this, I am wnating a simple way to show all current Session Variables which are set in the current session. These session variables are set when the user logs in and remain in effect till the user logs off.

My attempts have included the following;

$f = file_get_contents( "/tmp/".session_id() );
echo $f;

FAILS :
Warning: file_get_contents(/tmp/9a0553cdfcc15ff7f1e4bdf7722b282b) [function.file-get-contents]: failed to create stream: No such file or directory in /HIDDEN_VIEW/public_html/HIDDEN_VIEW/index.php on line 17


and

<? INCLUDE("/tmp/".session_id());

FAILS :
Warning: main(/tmp/9a0553cdfcc15ff7f1e4bdf7722b282b) [function.main]: failed to create stream: No such file or directory in /HIDDEN_VIEW/public_html/HIDDEN_VIEW/index.php on line 23

Warning: main() [function.main]: Failed opening '/tmp/9a0553cdfcc15ff7f1e4bdf7722b282b' for inclusion (include_path='.:') in /HIDDEN_VIEW/public_html/HIDDEN_VIEW/index.php on line 23


Help... what will correct this. I am the physical server owner in my facility. I mention this in case there is a config parameter that is needing to change.

Thanks in advance for your help...

either :
foreach ($_SESSION as $key=>$value) {
echo "variable '$key' is set to $value'
";
}

or

for ($i=0;$i<count($_SESSION);$i++) echo "variable '".$_SESSION[$i][0]."' is set to ".$_SESSION[$i][1]."'
";
