Syntax
| Parameter |
Description |
| strings |
Required. One or more strings to be sent to the output |
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>
