PHP Function to Format Megabytes to Gigabytes + Switch

Question

I have a table of data im importing, the contents of a particular row looks like this...

500, 1000, 2000, 4000, 5000, 8000, 10000, 12000, UNLIMITED

Each number represents Megabytes where as 8000 is 8000mb or 8gb I need a function which will knock off the last 3 zero's of the number if it is greater than 999 then add "GB" to the end of the number if not over 999 add "MB" to the end of the original number. so i end up with for each cell e.g. 500MB or 8GB - also I need the function to just echo "unlimited" in lower case if the case is "UNLIMITED" this would have been easy last year but im really rusty with my PHP at the minute and need a refresher course. Can you help me?

heres the code I have already wrote it doesn't work though...

function gigaplex($data) {
if ($data = 300) {
    echo "300MB";
} elseif ($data = 500) {
    echo "500MB";
} elseif ($data = 1000) {
    echo "1GB";
} elseif ($data = 2000) {
    echo "2GB";
} elseif ($data = 3000) {
    echo "3GB";
} elseif ($data = 4000) {
    echo "4GB";
} elseif ($data = 5000) {
    echo "5GB";
} elseif ($data = 8000) {
    echo "8GB";
} elseif ($data = 10000) {
    echo "10GB";
} elseif ($data = 12000) {
    echo "12GB";
} else {
    echo "unlimited";
}

}

I'd suggest you hire a programmer for that or try it yourself. — Ulrich Eckhardt, Feb 04 '16 at 21:57
I will be happy to answer this for you if you clean up your formatting so it's not confusing for other people to follow. EDIT: Where does the "Switch" come in to play? — jaggedsoft, Feb 04 '16 at 21:59
You should post some code which represents your effort. If you still have problems then we might help you. Noone here will do your work for free. Besides, what you want to do is pretty easy and is solveable with very basic functions. So stop being lazy and learn if you need to solve this. — Steini, Feb 04 '16 at 22:00
StackOverflow is not for "Please give me teh codez", if you try it, and you can't get it to work, post a question here showing what you have tried and we can help you. @NextLocal Just make sure you don't give too much away and keep the OP from a learning experience. Steini, let's be a bit nicer. — Ruan Mendes, Feb 04 '16 at 22:00
This is a good example of making zero effort and expecting the answer. — ggdx, Feb 04 '16 at 22:01

Look at the manual. http://php.net/manual/en/function.filesize.php See the first `User Contributed Notes` and modify as needed. — chris85, Feb 04 '16 at 22:07
Im not being lazy I have already wrote something but its long and ugly — mitchelangelo, Feb 04 '16 at 22:12
function gigaplex($data) { if ($data = "UNLIMITED") { echo "unlimited"; } elseif ($data = "300") { echo "300MB" } elseif ($data = "500") { echo "500MB" } elseif ($data = "1000") { echo "1GB" } elseif ($data = "2000") { echo "2GB" } elseif ($data = "3000") { echo "3GB" } elseif ($data = "4000") { echo "4GB" } elseif ($data = "5000") { echo "5GB" } elseif ($data = "8000") { echo "8GB" } elseif ($data = "10000") { echo "10GB" } else ($data = "12000") { echo "12GB" } } — mitchelangelo, Feb 04 '16 at 22:12
there is a problem with my code also it returns unlimited for a 10000 value??? — mitchelangelo, Feb 04 '16 at 22:23
i have pasted the code into my question that i just wrote but it wont work for some reason just spits out 300MB even though the value im passing to it is 10000 can anyone see a problem? — mitchelangelo, Feb 04 '16 at 22:34
it would be cool if I could say ask - if $data is 3 numbers ### or something echo them 3 numbers ### and add mb or if $data is more than 3 numbers #### delete the final three numbers and add a GB at the end but its too complicated at the minute because ive not been coding for a few years so ill just make a buff if else statement haha thanks Dagon — mitchelangelo, Feb 04 '16 at 22:43

Even if I don't think it's a good idea to check if $data is greater than 999 and cut the last 3 characters from your variable, this is exactly what you want:

function gigaplex($data) {
    if($data > 999) {
         $data = substr($data, 0, -3);
         $data .= "GB";
    } else if($data == 'UNLIMITED') {
         return 'UNLIMITED';
    } else {
         $data .= "MB";
    }
    return $data;
}

I would prefer this one:

function gigaplex($data) {
    if($data >= 1000) {
         $data /= 1000;
         return $data . "GB";
    } else if($data == 'UNLIMITED') {
         return 'UNLIMITED';
    } else {
         return $data . "MB";
    }
}

Divide the number by 1,000, and then round it down.

fuunction gigaplex($data) {
    if (!is_numeric($data)) {
        return $data;
    } elseif ($data >= 1000) {
        return floor($data/1000) . "GB";
    } else {
        return $data . "MB";
    }
}

I was just working on something similar although mind is a mess haha – mitchelangelo Feb 04 '16 at 23:03
function gigaplex($data) { if ($data =< 999) { echo $data."MB"; } elseif ($data => 1000) { $data / 1000 = $gigadata echo $gb."GB"; } elseif ($data == "UNLIMITED") { echo "unlimited"; } } – mitchelangelo Feb 04 '16 at 23:04
what will happen if the term inside the $data is a word like unlimited? – mitchelangelo Feb 04 '16 at 23:09
Didn't notice that in the question, I've added a check for non-numeric data. – Barmar Feb 04 '16 at 23:11
You need to check for non-numeric before testing the range. Otherwise, it will convert the non-numeric string to `0`. Also, there's no such thing as `=<`, it's `<=`. – Barmar Feb 04 '16 at 23:12
could i add strtolower($data) around $data in line 3 – mitchelangelo Feb 04 '16 at 23:25
Of course, why would think you think you couldn't? – Barmar Feb 05 '16 at 00:44
not been working with php for a while thanks for your help @Barmar – mitchelangelo Feb 05 '16 at 17:37
It's not really particular to PHP, it's just programming in general. When you're returning a value, you can always return the result of calling a function. – Barmar Feb 05 '16 at 19:05

This one works perfectly..

function gigaplex($data) {
   if($data == "UNLIMITED") {
     echo 'unlimited';
   } else if ($data >= 1000) {
     $data /= 1000;
     echo $data."GB";
   } else {
     echo $data."MB";
   }
}
