将字符串变量从php传递给JS函数

Question

I was looking for a way to pass a string(variable saved in a form of $x) from php to Java Script and I found so many codes to solve that, but my question is : does those strings have to be declared global?!
i did declare it as a global variable but still no response ..!
any other suggestions?!

Pass a PHP string to a JavaScript variable (and escape newlines)

I tried most of these codes, none of them worked,

As the others have said, all we can say is that you are doing something wrong. You can place PHP variable values, strings or otherwise, wherever you want in your JavaScript code, since PHP is server-side and can do whatever you like on the client side.
