Answer / manpreet
echo is a statement
while print is a function
we can't print whole array by using echo or print. For this
we have to use the print_r function

Answer / mahesh
echo is a statement where print_r,print are the functions
all prints the variable result..
If the variable is an Array, then Print_r will prints the
array in details (Array[0]-> " the array values")...
where as the other two(echo and print) only prints as ARRAY().

echo is not a function, but a statement which outputs one or
more strings, it cannot display the array contents where as
the print() and print_r() are functions. print() can even
display the array contents as an array . print_r() Prints
human-readable information about a
variable
