Fisrt thx to all for yours answers, I'm updating the mail because in
hte last mail I'didn express my self correctly :
EXAMPLE
page1.php
=======================================
<form action="/page2.php?form=yes" method="post">
$sql_pro ="SELECT Sid FROM table";
$res_pro = @mysql_query( $sql_pro);
while ($campo_pro = @mysql_fetch_array($res_pro)) {
$sid_pro = $campo_pro["Sid"]; //
$sid_pro = 4
$sid_pro = 'p'.$sid_pro; // I'm
trying to use the value of $sid_pro as a VAR name *$sid_pro =
p4* print "<td ><input name='$sid_pro' type=
'radio' // Here the Imput Name is a VALUE from Database
value='AAAA'/>* </td>"; // *name = p4 *
BLA BLA BLA
}
page2.php
// I Need to access a value from the form witch it's stored in a VAR
called $p4
// The Name of the VAR "$p4" It's stored in my database, so How can I
convert a database string to a VAR NAME
=======================================
$sqlname = "SELECT Sid FROM Table";
$res = mysql_query ($sqlname) ;
while ($campo_pro = mysql_fetch_array($res)) {
$name1 = $campo_pro["Sid"]; // *$name1 = 4*
$radio = '$'.'p'.$name1 ; // *$radio = $p4
----------------------
Now the Problem
**How can I get the Value SOLVE_ME from the submited form ?*
echo '$radio'; // == $p4 => WRONG i need AAAA
// The VALUE of $radio witch is "$p4" is the name of the VAR
I need to access, how can I export the VALUE "$p4" AS a VAR Name ?
}
Small example that might help solve it:
$foo = "bar";
$$foo = "Hello World!";
echo $bar; // Prints out Hello World!

Thx for your answer Berry,
What if I don't know the value of "$foo " (witch is "bar")
so we have this :
$foo = "UnKnowName";
$$foo = "Hello World!";
Here is the problem
// remember that I dont know the value of $foo
echo .'$'.$foo // prints out $UnKnowName but I need to prints out Hello
Worlds!
so If I don'r know the value of $foo, what can I do tu prints out
Hello World!
Thx in advance.
echo $$foo
