convert a string to integer

Hi,

i know this topic is obvious but i have a strange behavior and i'm getting
crazy.

my stored procedure returns me a string.
string can be an email or a message error => '-1', '-2', '-3'

when i check if the string contains only digit, i use ctype_digit(mystring)
but any way it returns me false... i suppose that for -1, -2, -3 the "-" is
taken as character and not a digit.
i tried also to cast it before into integer thanks
ctype_digit((int)mystring), but it does not work.

so how can i solve this issue ?

thx

is_numeric() - "Finds whether the given variable is numeric. Numeric
strings consist of optional sign, any number of digits, optional
decimal part and optional exponential part."

Windows is a joke operating system. Hell, it's not even an operating
system. NT is Not Tough enough for me either. 95 is how may times it
will crash an hour.
