Both echo and print are used to output data, but they have key differences:

• Return value: echo has no return value, while print always returns 1
• Parameters: echo can take multiple parameters, print can only take one
• Speed: echo is marginally faster since it doesn't return a value
• Usage: echo can be used with or without parentheses, print can also be used both ways

echo "Hello", " World"; // Works
print "Hello World";     // Works
// print "Hello", " World"; // Error - multiple parameters not allowed
