PHP compare order?

Does it matter in php?

In PHP does it matter which way you compare?

if("Registesr" == $SomeVariableOr['Thing']){DoSomething();}
Or
If($SomeVariableOr['Thing'] == "Register"){DoSomething();}

Thanks

Not for this case. It would obviously matter if you were using other comparison operators such as less than (<) or greater than (>), though.
