How does the behavior of echo and print differ when it comes to outputting multiple parameters/strings in PHP?

When outputting multiple parameters/strings in PHP, the behavior of echo and print differs in that echo can output multiple parameters/strings separated by commas, while print can only output a single parameter/string at a time. To output multiple parameters/strings with print, you would need to concatenate them using the dot (.) operator.

// Using echo to output multiple parameters/strings
echo "Hello", "World";

// Using print to output multiple parameters/strings
print "Hello" . "World";
