help with if statement

[MDanz]

$tags = get_meta_tags($url);

 

i have this variable.  I'd like to do an if statement.

 

If ($tags able to get meta tags) {} else {}

Well, never used this func so can't be sure but I assume it returns false if fails so:

 

if($tags = get_meta_tags($url)){
// do stuff
}else{
// do something else
}

 

Not entirely sure assigning vars within an argument is best practice though, so you could use a ternary operator instead:

 

$tags = (get_meta_tags($url)) ? get_meta_tags($url) : false;

if($tags){
// do stuff
}else{
// do something else
}
