PHP learning: Understand the differences between echo, print, and vardump statements

We all know that PHP has a lot of print output, PHP echo, print, vardump, so what is the difference between them? Below I will take you to learn more about it, I hope it can be helpful to you.

1.echo statement

echo - can output more than one string

   <?php
      echo "<h2>www.dc3688.com</h2>";
      echo "Hello world!<br>";
      echo "I&#39;m about to learn PHP!<br>";
       echo "This", " string", " was", " made", " with multiple parameters.";
     ?>

2, print() statement

print - can only output one String, and always returns 1

<?php
print "<h2>www.dc3688.com</h2>";
print "Hello world!<br>";
print "I&#39;m about to learn PHP!";
?>

3, vardump prints the array

Prints all objects and views the data structure inside the object

Note that echo is slightly faster than print because It returns no value.
