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
