错误“语法错误，意外'preg_match'（T_STRING）在”

Question

I keep getting this error message saying:

syntax error, unexpected 'preg_match' (T_STRING) in

In this line:

Public function isDataValid()
{
return (preg_match('/^[a-zA-Z0-9](5-12)$/',$this->_username) (preg_match('/^[a-zA-Z0-9](8-12)$/',$this->_password)))? 1 = 0;

Can't figure this out. Help

Answer 1

The error is about second preg_match because you have missing && OR || between those conditions. And also wrong = must be : if you use one line statement of if like below.

(condition) ? "here_what_if_the_condition_is_true" : "and_here_if_it_is_wrong" ;

look:

return (preg_match('/^[a-zA-Z0-9](5-12)$/',$this->_username) (preg_match('/^[a-zA-Z0-9](8-12)$/',$this->_password)))? 1 = 0;

And correct one is:

return (preg_match('/^[a-zA-Z0-9](5-12)$/',$this->_username) && (preg_match('/^[a-zA-Z0-9](8-12)$/',$this->_password))) ? 1 : 0;
