PHP echo and print Statements

There are some differences between echo and print:

echo - can output one or more strings
print - can only output one string, and returns always 1

Tip: echo is marginally faster compared to print as echo does not return any value.

The PHP echo Statement

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

Display Strings

The following example shows how to display different strings with the echo command.

<?php
echo "<h2>PHP is fun!</h2>";
echo "Hello world!<br>";
echo "I'm about to learn PHP!<br>";
echo "This", " string", " was", " made", " with multiple parameters.";
?>

Display Variables

The following example shows how to display strings and variables with the echo command:

<?php
$txt1="Learn Programming";
$txt2="BizHat.com";
$cars=array("Volvo","BMW","Toyota");

echo $txt1;
echo      "<br>";
echo "Study PHP at $txt2";
echo "My car is a {$cars[0]}";
?>

The PHP print Statement

<?php
print "<h2>PHP is fun!</h2>";
