echo VARIABLES

[Maximus]

Guys,

I have a mysql query that grabs data from the table ... the data is
"variable names" something like $home $about $contact

I need the loop to echo those variables as PHP Code, so that they are
replaced with the variable value and not the variable name.

any quick function for that?

Hi,

$bla = "myvarname" ;
$myvarname = "I am some var";
echo $$bla;

Re: echo VARIABLES

That's not the case,

The case is: I have a database table with rows ID and NAME

ID=1 NAME=$home
ID=2 NAME=$about

I make a mysql_fetch_obj ect that grabs the data and echos it in a
table. I want it to echo $home where $home is a variable with some
value.

I need the user to view the $home value .. not the word "$home" itself.

That's exactly what the posted example does. Have a look at variable
variables.

Hi,

I am not sure I can follow you.
Did you actually try my code example?
It doesn't show '$myvarname', but 'I am some var', which is the content of
the variable $myvarname, which is defined by $bla.

So what is the difference with your problem?

In your case you'll end up with a row, like this:
for(..fetchrows tuff in $row..){
echo $row["NAME"]." contains:".$$ro w["NAME"];
// or cleaner IMHO:
echo $row["NAME"]." contains:".${$r ow["NAME"]};
}

Or am I brainfarting and missing your problem?
