what 's the meaning of $$link?

[hurstchoi]

function tep_db_connect($server = DB_SERVER, $username = DB_SERVER_USERNAME, $password = DB_SERVER_PASSWORD, $database = DB_DATABASE, $link = 'db_link') {

global $$link;

if (USE_PCONNECT == 'true') { //current :false , so do not used now.

$$link = mysql_pconnect($server, $username, $password);

} else {

$$link = mysql_connect($server, $username, $password);

printf("tep_db_connect result(mysql_connect performed !! ): %s \n",$$link);

}

 

if ($$link) mysql_select_db($database);

 

return $$link;

}

 

 

Dear whom may concern:

 

I am beginner developer in PHP. When I see $$link. I could not understand it. the code is working now well.

but I want to know the meaning. whey define " global $$link " in upper code?

 

Are there anyone? Could you explain the meaning. I was a programmer in 10 years in others field, not php.

but I know php a little and I could fix the osc code a little.

 

Best regards.

I think he wants to know how variable variables work Chris.

 

Example: -

$test = 'testing';
$$test = 'tested';
echo $testing; // outputs tested

 

$$test is taking the value of $test and assigning it as a variable name with the value of tested.
