Hello dear colleagues from the talkphp forum,

I would very much appreciate some help regarding the following subject:



This routine is returning the result:
$variable1

I would like to get the value "Hello" instead.

Can someone explain to me which php function can I use to retrieve the result that I am looking for ?

Thanks in advance,

This is a simple enough issue to fix...

When you use single quotes ( ' ), PHP reads the string literally!
If you use double quotes ( " ), PHP tries to parse variables and other information contained in the string.
I see that you use concatenation (using the period "." to connect two or more strings) which can be used like so:


Also, since you don't have anything special in your $title definition second part ,you can also do this:


Really, the variable doesn't need to be in any quotes unless it is in the middle of a string and then it has to be in double quotes to work but closing a string then using concatenation to add the variable to the string then use concatenation again before opening your quotes again to continue your string definition like so:

would look like this:
This is me string which is the first string in the code.

There are other ways to do what you are wanting including string replacement or regular expression replacement.

Hi,

What I really was looking for was this solution:

echo $$title;

please notice the $$

Thanks for helping,

I think this will help:

Would print:
$hello

You can use the backslash (\) character to escape a single character. Or the following would also work:

This is because the single quote tells PHP not to look for any variables in the string.
