In PHP, both echo and print statements are used for outputting data. The main differences are as follows:

  1. Syntax: The echo function does not have a return value and can take multiple arguments separated by commas. The print function has a return value of 1 and can only accept one argument.
  2. Execution speed: echo is faster than print because echo does not have a return value.
  3. Usage: echo can be used directly within HTML tags or in PHP code. Print can only be used in PHP code.
  4. The output results: the echo statement can be used without parentheses to output strings, variables, and expressions. The print statement must use parentheses to output only strings.

I am unable to attend the meeting tomorrow because I have a doctor’s appointment.

$name = "John Doe";
echo "Hello, " . $name; // 输出：Hello, John Doe
echo "The sum is: ", 2 + 3; // 输出：The sum is: 5

print("Hello, " . $name); // 输出：Hello, John Doe
print("The sum is: " . (2 + 3)); // 输出：The sum is: 5

In general, echo is more commonly used and more flexible, while print may be more convenient in certain specific situations.
