PHP - Echo | How to print in PHP | PHP echo new line | php Echo Syntax - Function - Code - Example.

As you saw in the previous lesson, the PHP command echo is a means of outputting text to the web browser. Throughout your PHP career you will be using the echo command more than any other. So let's give it a solid perusal!

Outputting a String

To output a string, like we have done in previous lessons, use PHP echo. You can place either a string variable or you can use quotes, like we do below, to create a string that the echo function will output.

PHP Code:

<?php
$myString = "Hello!";
echo $myString;
echo "<h5>I love using PHP!</h5>";
?>

Display:

Hello!

I love using PHP!

 

Tips and Notes

Note: The echo() function is not actually a function, so you are not required to use parentheses with it. However, if you want to pass more than one parameter to echo(), using parentheses will generate a parse error.
Tip: The echo() function is slightly faster than print().
Tip: The echo() function has the following shortcut syntax. See example 5.

Example 1

<?php
$str = "Who's Kai Jim?";
echo $str;
echo "<br />";
echo $str."<br />I don't know!";
?>

The output of the code above will be:

Who's Kai Jim?
Who's Kai Jim?
I don't know!

---

Example 2

<?php
echo "This text
spans multiple
lines.";
?>

The output of the code above will be:

This text spans multiple lines.

---

Example 3

<?php
echo 'This ','string ','was ','made ','with multiple parameters';
?>

The output of the code above will be:

This string was made with multiple parameters

---

Example 4

Difference of single and double quotes. Single quotes will print the variable name, not the value:

<?php
$color = "red";
echo "Roses are $color";
echo "<br />";
echo 'Roses are $color';
?>

The output of the code above will be:

Roses are red
Roses are $color

---

Example 5

Shortcut syntax:

<html>
<body>

<?php
$color = "red";
?>

<p>Roses are <?=$color?></p>

</body>
</html>
