the use of is_null

[mikhl]

Hi people,

 

I recently has a simple if statement like below:

 

if(!is_null($var){
       //some code
}

 

and it was not working. So I changed it to:

 

if($var != null){
       //some code
}

 

After that it worked just as expected; am I missing something. I am a little confused.

Post the code that isn't producing the results you think it should, tell us what you think the results should be, and include the values of the variables you're using.

if(!is_null($var){
       //some code
}

 

Is not going to work because you missed a parenthesis.

 

if($var != null){
       //some code
}

 

Is not working because you have to assert type as well by adding an extra equal sign: !==
