Question

I got this variable

$test = 'Alpha, Gamma, Beta';

What is the best practice to get this result? How do I add a certain word in between such as I did below add Rays.

Alpha Rays, Gamma Rays, Beta Rays

Answer 1

Try this code piece

$test = preg_replace('/(,|$)/', ' Rays$1', $test);

I can’t tell if it is “Best practice”, but it is a practice that works and is simple. You can probably make another solution which would give you better performance, and that might be “best practice” if performance is the issue.

But if simplicity is the way, this is good.

Edit:

Since some other answers are using str_replace, I can give a working solution for that too:

$test = str_replace(',',' Rays,', $test).(empty($test)?'':' Rays');
