Strings and Concatination

Hello im trying to do this:

Im deep into strings right now and i have a line where i need to merge a string of text and a dynamic variable to produce the value of the 2 combined e.g

i have a string of text "question" and i have a variable $number the number is in a loop so it increments so i could have

question1
question2
question3

etc

but what i want to do is have it display the value of question1 e.g "How do you spell red" and not echo "question1"

any help would be greatly appreciated i have a feeling it has to do with brackets or parenthesis.

Thanks, -Tim

 

You mean like...

$question = ${'question' . $number};

PHP:

??


You're better off using arrays though...

 

Worked perfect, thank you for your time. rep added. yea i wish i used an array from the start uuuuugh lol.

 

It's never too late to improve your code.

 

Hey,
Suppose you need to print from 1 to n questions, you can do:

foreach(range(1,$n) as $num)
{
     $question = $('question'.$num);
}

In your original program, if you use $$ (double), it will print what you require.

e.g.

echo $$question;

it will print "How do you spell red"

 

thank you for future tips
