is there a method for checking if a string is only Alphanumeric?

Well you should research what the string codes are.

here is the argorithm.

1. Get the Size of String ( using sizeof() )

2. check the letters whether they contain forbidden ones.

3. if they do, return;

4. if not, do what you want

PHP Code:


for(new i = 0; i < sizeof(String); i++)
{
      if(String[i] <= ? || String[i] >= ?) return;//Every Char has its own numbered label that indicate the Char
                                                            // For Example, In unicode a has 97 label in Dec. So you can restrict the lable

      do what you want
}

stock bool:IsAlphaNumeric(const String:str[])
{
	for (new i = 0; i < sizeof(str); i++)
	{
		if (!IsCharAlpha(str[i]) && !IsCharNumeric(str[i]))
		{
			return false;
		}
	}
	return true;
}

Edit: Use strlen(str) instead of sizeof(str)

iv been working on a bool thing to check just struggling atm, why im asking if something already exists but ty for you input!

looks pretty similar to what iv been working to get haha ^^ but ty for this ill give it a whiz

[Nano2e]

okay got it working, ty allot fellas

Oops I didn't know that functions.

TY for teaching me that ones

This is UTF-8 unsafe. You should never access individual bytes of string if you want to support code points outside of ASCII range. Unfortunately, there is no easy way to access code points either.

I've made a proposal about better strings in the donor forum but so far it didn't gain much support.

This function is UTF-8 safe, because out-of-range bytes will fail the character class tests.

Hey. I have some question.

I want to make some extension to make 64-bit integer or something.

could you please, inform me where to learn the basic..?
