Strval has one parameter, in that parameter you put the string you want to convert into an integer instead.

pawn Код:

new string[4] = "255"; // This is just made up of characters.
new variable = 255; // This is a number.

So the code below wont work....The string is 255, but it is just a string, not a number.

pawn Код:

GivePlayerMoney(playerid, string);

Instead you would use strval to convert the string into a number.

pawn Код:

new string[4] = "400";
GivePlayerMoney(playerid, strval(string)); // This converts the string into the number 400 and will give the player the money.

Strlen just counts the characters in a string, and returns an integer.

Example.

pawn Код:

new string[11] = "Hello John";
printf("String has %d characters in it.",strlen(string));

Will print

Код:

String has 10 characters in it. Since there are 10 chars in the string.

Hope I helped.
