Well this gonna work and it's very good code, but not perfect. The first thing to get in your mind is to do so : $string = 'This is some string' What if we have a string and we want to check if it's less than or equal to 5 ?

The first parameter is the string you want to count, and the second is the encoding. But if you want to count letters and you're not sure if there will be any unicode letters then we gonna use another function which is mb_strlen as follow : $string = 'Tschüss' Well if you're sure the string wont has any unicode letters or you really want to count the bytes not letters then strlen() will be okay. Note : There is no simple answer about the 1~6 bytes letters, so we wont go deep into it now, maybe another tutorial. and 'ü' is 2 bytes so PHP counted it as 2 letters. This should output 7, cause 'Tschüss' word is consist of 7 letter, but hey this how humans count it but not in programming, actually 'Tschüss' consist of 8 letters and this snippet will output 8 notĪctually strlen() doesn't really count letters, but count bytes, the letter 'ü' is unicode letter, and unicode letters are not 1 byte all the time but it's 1 ~ 6 bytes. Good Enough, lets take another example from German language. This will output 5 for sure, cause 'Hello' word is consist of 5 letters. This is the way most of us know about, and many coders just use it all the time $string = 'Hello'

The title may look very common and very basics thing, cause it's known that you can use strlen function to get string length, but actually it's not that simple there are many things you've to keep in mind while working with strings length, so lets get into this guide.
