As you know, the @ characters before a php istruction suppress every eventual warning, error or notice from being raised.
Personally, i dont like this tecnique, becose i prefer to handle those errors, and in a real life, the error must no happen or have to be managed.
By the way, i find this tecnique to be applied in many scripts (cms plugins, open-source classes).
So, could the @ really be usefull (in this case, an example would be appreciated), or is just for lazy developers?
