PHP echo/print

php What is the difference between echo and print and the usage of statements?

There are two basic output methods in PHP: echo and print.

In this chapter we will discuss in detail the usage of the two statements and the difference between echo and print, and demonstrate how to use echo and print in examples.

PHP echo and print statements

The difference between echo and print:

• echo - can output one or more strings

• print - Only one string is allowed to be output, and the return value is always 1

Tips: echo outputs faster than print , echo has no return value, and print has a return value of 1.

PHP echo statement

echo is a language structure, which can be used without parentheses or with parentheses: echo or echo().

echo "Hello world!<br>";
echo "I'm about to learn PHP!<br>";
echo "This", " string", " was", " made", " with multiple parameters.";
?>

$cars=array("Volvo","BMW","Toyota");

echo $txt1;
echo "<br>";
