Meaning of $$ variable

[Edward999]

Hi I'm new to PHP. I need to know the meaning of $$variable.

My source code as below:


foreach($template_field as $key => $val) {

$varname[] = $namevar = "template$key";

$$namevar = $valuez;}

Why we use $$namevar?....Please help

Thanks in Advance

$varname = "myVar";
$value = 5;

# now watch:
$$varname = $value;

echo $myVar;
# output will be: 5

By using the $$ sign you assigned a value to a variable that itself comes from a variable. Ok?

What we're talking about here is what the PHP online manual calls "variable variables"

There is a section in the online manual which talks about variable variables.
