How to use the address bar to pass variables

How can I use the address bar to pass variables? I have some code & lt; td & gt; User: & lt ;? Phpecho $ array [user];? & Gt; Title: & lt; ahref & quot; localhostdiscussanswer. php? Link & lt ;? Php $ array [title];? & Gt; & quot; & gt; how to use the address bar to transmit variables
Ladies and gentlemen, I have some code
User: Title: ">

It is the title. I want to jump to another page and pass the value of $ array [title] to the next page. I tried it.
Link = It seems useless. it seems that only constants can be passed after link =. Because there are many headers in the database, each of which can open the next page, variables are used. How can this problem be solved?

------ Solution --------------------
First, make sure that $ array ['title'] has a value. On the next page, print_r ($ _ GET); what do you see?
