Hi, I'm been writing PHP for about 2 weeks now. I seem to learn something new each day. Anyway,

One poster said to use print_r and var_dump rather than echo. I just what to know why we should use those functions rather than echo? What's the main difference between them?

Thanks

Use var_dump or print_r if you want to view the structure of an array or an object.

http://www.php.net/var_dump
http://www.php.net/print_r

These do not work in place of echo! These are utility functions that provide information about a variable. Perhaps you are thinking of print. Whereas print and echo are language constructs, not functions, these are functions.

And for a detailed explaination of the differences between the two:
