Syntax
int pad ( string sourcestring, string length, string padchar )
Description
pad returns a new string at the exact length of characters long. The beginning of the string is the sourcestring.
If the length argument is bigger than the size of the sourcestring, then the returned string is padded with the padchar argument. Otherwise, the first length characters of sourcestring are returned.
The padchar argument can also contain multiple characters, in which case the characters return padded repeatedly.
Example
result = pad("123",5," "); {
# returns "123"
}
result = pad("123",6,"<>"); {
# returns "123<><"
}
result = pad("User Name", 3, " "); {
# returns "User"
}
Syntax
int strindex( string str, string substr )
Description
strindex returns the numerical offset of a given string within another string. If the substr is not found, it returns -1.
Example
printf("%d\n",strindex("xxxfooxxx","foo"));
Returns: "3"
printf("%d\n",strindex("xxxfooxxx","bar"));
Returns: "-1"
Syntax
int strlen( string str )
Description
strlen returns the length of the string, str.
Example
printf("%d\n",strlen("foo"));
Returns: 3
Syntax
string strsub ( string str, int start, int length )
Description
strsub returns the substring of a given length starting at a given position in the string.
Example
printf("%s\n",strsub("xxxfooxxx",3,3))
Returns "foo".
printf(%s\n",strsub(xxxfooxxx",3,-1))
-1 returns the remainder of the string, "fooxxx".
