SESSION to Var

[johnrb87]

Hello everyone

 

I have the following code

 

$num = 1;
$query = mysql_query("SELECT * FROM people");
while($row = mysql_fetch_array($query))
{
$nums = $num++;
$_SESSION['equal'.$nums.''] = $row['name'];
$_SESSION['total'.$nums.''] = $row['age'];
}

 

which basically returns me SESSION names by increasing by 1, so it could produce the following session names

 

equal1
total1
equal2
total2
equal3
total3
equal4
total4

 

instead of setting those as sessions, I simply want to set them as vars, so instead of

 

$_SESSION['equal'.$nums.''] = $row['name'];
$_SESSION['total'.$nums.''] = $row['age'];

 

it would look like

 

$equal.$nums = $row['name'];
$total.$nums = $row['age'];

 

I have tried

 

$equal.$nums = $row['name'];
$total.$nums = $row['age'];

 

but it doesn't seem to work

 

any ideas?

 

thanks

These are known as variable variables.

Thanks

 

I'm quite new to PHP, the page was quite overwhelming, but I tried

 

$equal.$nums = $row['name'];
$total.$nums = $row['age'];

 

but that didn't seem to work, and also tried

 

$equal[$nums] = $row['name'];
$total[$nums] = $row['age'];

 

but that also failed.

 

Any suggestions on what I can try?

 

Thanks

Your second option to use an array is the best option as opposed to variable variables.

<?php
$results = array();
$num = 1;
$query = mysql_query("SELECT * FROM people");
while($row = mysql_fetch_array($query)) {
$results[$num] = array('name' => $row['name'], 'age' => $row['age']);
$num++;
}

/* now you can extract values from the array */
print "name: ".$results[1]['name'].", age: ".$results[1]['age']."<br />";
print "name: ".$results[2]['name'].", age: ".$results[2]['age']."<br />";
?>
