Echo is marginally faster than print, and print returns a value, echo does not.

Echo allows comma separated arguments which it will concatenate. Print accepts only a single argument, but this is hardly a deal-breaker, because you can concatenate with a dot anyway.

Echo does not have a place in the precedence table, which means you can't use it in a complex expression.

That said ... for most cases, the major significant difference is:

Echo is quicker to type :)

Print outputs a single string, echo can output multiple strings. (It's in the help file.)

I just received my RSQ-echo 2000 karaoke machine. When I plug a mic into the front 2 mic inputs, they both have echo, even tho I turned off the echo volume in the back. I assumed that by turning it all...

The control supposedly controls the mix of the echo... this is a reverb type sound. Please note that room acoustics AND if the mic's "hear" the speaker in this, it may create an echo that is NOT under control of the adjustment. Make sure the mic's cannot "hear" the speaker or a reflection off a wall.

Need oil/gas ratio for Echo back pack lblower - model PB-400E

Since every engine is different the manufacturer almost always has it printed in the gas cap. It should look like 50:1 or 50/1 (50 parts gas to 1 part oil).

This is an illustration of use of classes in php please tell me do i need to put the classes in seperate php file and the objects in seperate file or in other words for the below example how many seperate...

Everything can be in the one file if you want, but that doesn't help with segregation of logic from the presentation layer (i.e. what you see on screen).

Personally I'd put my core class libraries in one or more files and include() them. And I'd probably put any extended classes in separate files and include() them additionally.

include ('library.class.php');
include ('extended.class.php');

Hp g6000 running very slow any suggestions.

The HP g6000 slow issue can be caused by many many reasons such as outdated hardware, overload startup programs, corrupt registry issues, too many junks, virus attack, poor security software taking too much system resources, remnants of uninstalled applications etc. The fact is, you should keep some system maintenance job regularly. If you don't want to do these manually, try the solution to give a free & full scan of your slow HP PC to find & fix all possible issues.

Meanwhile, upgrading hardware configuration (add RAM, change a new video card, larger-volume HDD etc) can be a fast yet effective way to improve your pc performance.
