Simple PHP, show String but encoded, affected in URL Parameter [duplicate]

Question

how are you today..?

hi all...

I found something odds, and very tricky..

echo "&currency"; //return ¤cy

echo "&ethnic"; //return ðnic

Why is this happened..? its affected on URL query.

it seemed that the string is encoded ASCII, how to fix it..?

this is the loop.. tried to replace & to & amp ;

foreach($pars as $key => $val) $param .= "&".$key."=".$val;

but its having so many errors...

Thankyou.

1. You need to HTML-encode the & character as &. 2. how are you today - brilliant — Ken Lee

You can find this symbol here https://dev.w3.org/html5/html-author/charref.

Use urlencode() to solve your problem with URL query.

http_build_query(), if used properly, absolutely does solve this. stackoverflow.com/a/62055171/2943403
