[php] How are echo and print different in PHP?

Reference: Comparing PHP's print and echo

Is there any major and fundamental difference between these two functions in PHP?

To add to the answers above, while print can only take one parameter, it will allow for concatenation of multiple values, ie:

$count = 5;

print "This is " . $count . " values in " . $count/5 . " parameter";

This is 5 values in 1 parameter

I think print() is slower than echo.

I like to use print() only for situations like:

 echo 'Doing some stuff... ';
 foo() and print("ok.\n") or print("error: " . getError() . ".\n");

They are:

• print only takes one parameter, while echo can have multiple parameters.
• print returns a value (1), so can be used as an expression.
• echo is slightly faster.

As the PHP.net manual suggests, take a read of this discussion.

One major difference is that echo can take multiple parameters to output. E.g.:

echo 'foo', 'bar';   // Concatenates the 2 strings
print('foo', 'bar'); // Fatal error

If you're looking to evaluate the outcome of an output statement (as below) use print. If not, use echo.

$res = print('test');
var_dump($res); //bool(true)
