perl - Why a full stop, "." and not a plus symbol, "+", for string concatenation in PHP? -

-

Why did the PHP designer decide to use a full stop / duration? " As compared to the more common plus symbol "+" as the string concatenation operator?

Is it any advantage, or for some reason? Or do they just like? : O)

The most obvious reason is that PHP has many syntax Perl - and uses a dot (. ) for parl string synthesis

But, we can put a deep crater in it and understand why it was implemented in Perl - most of the + operator for mathematical equations Is used - it is used only for inclusion in those languages, in which the variable type can define the method in which the operator works (simple explanation, for example C #) 

 < Code> var intAddition = 1 + 2; Console.WriteLine (intAddition); // print 3 var string concrete = "1" + "2"; Console.WriteLine (stringConcat); // print "12"

^ As you can see, the + operator is used for both concatenation and C.

The argument goes to the low level and is caused by the Boolean algebra in the door of logic - + means or while . is used as and as an operator - which makes sense when it comes to string containment.

It is understood by two different operators, for one combination and for an additional - it is only unfortunate that these two languages ​​can be mixed due to other languages.

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
