php if else alternate syntax

Question

Is it possible to write the if syntax somewhere close to this:

if (function($value)) else {echo "Error Message";}

If function($value), nothing needs to happen. The function returns true, but if not, I need the Error Message and I cant put that Inside the function.

Any idea how to do this?

You do not need to include a case at all if nothing needs to happen. Thus, what you are looking for is:

if (!function($value)) {
    echo "Error Message";
}

I think I got too caught up in the single line syntax. +1 for a nice simple answer.

You can still write this on a single line, as if (!function($value)) echo "Error Message";, or similarly if (!function($value)) { echo "Error Message"; }.

Yes lol, I just didn't think of the simplest answer of using ! in the check :)

This is a better approach:

if (!function($value)){echo "Error Message";}

You can actually do this by inserting an empty statement:

if (function($value)) ; else {echo "Error Message";}

You could use a ternary to do this:

echo (function($value)? "" : "Error Message";

+1 This is a definite candidate for Ternary over normal IF ELSE

return (function($value)? true : "Error Message");

returns true on valid else will return a string, which can be echoed outside.

The Best way:

if (function($value)==0)
{
echo "Error Message";
}else{

//Execution code
}
