PHP warning: implode (): Invalid parameter transfer

How can this problem be solved ???

Reply to discussion (solution)

What is var_dump ($ gets) before that sentence?

$vv["get"] = array("del"=>"0","dept"=>"2");$gets = "";foreach($vv["get"] as $g => $gv){  $gets[] = $g."=".$gv;}     $gets = implode("&",$gets); echo $gets;

Del = 0 & dept = 2
No problem

But it is best to use the http_build_query function.
$ Gets = http_build_query ($ vv ['get']);

Should explode be used to convert it into an array? Implode is an array to a string ~~

Your $ vv ["get"] variable may be faulty.

Sorry, I cannot change the original sentence.
