Question

What is the difference between these three?

return , echo and print keyword in PHP

function theBand($abc,$bac) {

return $abc;
echo $abc;

}

Both does the same, it does show or return me the value holding in the variable abc. Now return exists the function and echo continues. Apart from this is there anything specific on return keyword.

Answer 1

return is a language construct used to exit a function and give a value to the caller of the function.

echo and print are both language constructs that output strings. The main difference is that echo can take multiple arguments separated by commas, but print accepts only a single argument.
