[RESOLVED] Append a prefix to a session variable name

[adi]

Hi. I'm trying to automatically build a session variable wich has a name based on a prefix + content of another variable. For example :

echo '<tr><td>Tariff  '.$label_type.':</td>
<td> <input type="TEXT" name="tariff_'.$tariff_type.'" value="'.$_SESSION['tariff_$tariff_type'].'" ></td>'</tr>;

It works if i don't use the prefix (tariff) and i take out the single quotes :

value="'.$_SESSION[$tariff_type].'"

But if i use the prefix it doesn't work:
value="'.$SESSION['tariff$tariff_type'].'"

Thank you.

I always find it's eaiser to deal with simple problems like this in smaller scripts.. removing the unneeded html.. such as

<?php
$foo = "bar";

$session['text_$foo_text'] = "value";

echo "<pre>";
print_r($session);
?>

which has an output of

Array
(
    [text_[B]$foo[/B]_text] => value
)

notice $foo isn't the value "bar", but instead the variable name.

so, to add a variable to a variables array, you use a [..whatever the "." is called] just like you would in a normal string:

<?php
$foo = "bar";

$session['text_'.$foo.'_text'] = "value"; // <<<<

echo "<pre>";
print_r($session);
?>

which has an output of

Array
(
    [text_[B]bar[/B]_text] => value
)

notice the value of $foo is the actual value "bar", and not the variable name
