Why if(!mysqli_prepare($conn,$query) Fails ?

Php Folks,

Why this one doesn’t work …

[code]
if(!mysqli_prepare($conn,$query)
{
//Close Connection.
mysqli_close($conn);
die(“<pre>Mysqli Prepare Failed!n”.mysqli_prepare($conn,$query).”n</pre>”);
}
[/code]

While this one does ….

[code]
$stmt = mysqli_prepare($conn,$sql_query);
if($stmt == False)
{
//Close Connection.
mysqli_close($conn);
die(“<pre>Mysqli Prepare Failed!n”.mysqli_stmt_error($stmt).”n$sql_query</pre>”);
}
[/code]

Pretty much the same aren’t they ?
First one my own code.
Second one suggested by NogDog, if I remember correctly.

For some reason, php gives no response to this line:

[code]
if(!mysqli_prepare($conn,$query)
[/code]
