When to use single quotes in if statement == for numbers or do i?

superaff1984 · Feb 23, 2025

I have a question, I can't recall, but when using if statements. I know when using == towards letters you have to use single quotes. For example if(variable == 'dog'){ this is true}

However, are numbers different. I think this code below would execute to true if the $starcard variable matched the number or do I need to put the number into single quotes?

Clearly, I am going to test it, but just making sure to avoid any issues.

if($strcard == 533248){
will be true?
}else{}

Single quotes shouldn't be needed when matching numbers like that. But there are many different programming languages out there - there might be one where they are needed. So like you say, just test anyway.

Is this PHP?

Figured you probably know the answer by now, but just in case anyone else is interested, you can use the == operator on both strings (the letters in your example) and numbers.

You should not put the 533248 value in quotes as it'll then be a string. Strings and numbers are different data types in programming languages, so you'd want to omit the quotes for the number, just like you have in your example.

I am not a "php" guy, but you might want to relook at data types in the programming language. == is just a loose equality checker

Yep, numbers are different; you don't need the single quotes there.

You're absolutely on the right track! No need for single quotes around numbers—PHP can handle that like a champ.

So, your if($strcard == 533248) will indeed be true if $strcard holds the number 533248, even if it's a string like "533248", because PHP will do some loose comparison magic and convert it for you.

But if you want to be extra strict (like a teacher checking homework with a magnifying glass), use === instead of ==. That way, it’ll only return true if $strcard is exactly the same type and value (i.e., an integer, not a string).

So:

if($strcard == 533248) {} → Works fine (loose comparison)
if($strcard === 533248) {} → Works, but only if $strcard is really an integer

Yep, numbers are different; you don't need quotes there. Just make sure your variable's actually an integer if you're expecting an integer comparison!
