Weird error

[uniique]

Hello,

 

I get a weird error from this part of code

 

Line 181

if (!empty(self::SLAVE1_HOST)) {

 

Parse error: syntax error, unexpected ')', expecting '(' in *** on line 181

 

What is wrong with this part of code?

If you replaced self::SLAVE1_HOST with $var, what happened?

if(!empty ($var)){
    
}

then it works ^^

 

so i have to put self::SLAVE1_HOST into a $var and it will work then?

No, start from here -> http://php.net/manual/en/language.oop5.php

I was rather hoping to get a short hint instead of pointing me to the manual

Yes, but everything is there 

You have to post the class, b/s I don't know the structure.

Try

if (!self::SLAVE1_HOST))

this is the Class

You need learn more of OOP and PDO.

In this case use:

if (self::SLAVE1_HOST))

It's not my class, I use it as a wrapper for PDO, I was just wondering, why this error occurs. So one can only perform empty on $vars?

B/s empty and isset function doesn't work with constants.

Simple test:

define("CONSTANT", "Hello world.");

if(empty (CONSTANT)){
echo CONSTANT;    
} else if(isset(CONSTANT)){
echo '....';   
} else {
echo CONSTANT;   
}

 

You have to use defined()

if (defined('CONSTANT')) {
    echo CONSTANT;
}

ok, thanks for the explanation
