PHP
5 echo and print Statements
In PHP there
are two basic ways to get output: echo and print.
In this
tutorial we use echo (and print) in almost every example. So, this chapter
contains a little more info about those two output statements.
PHP echo and
print Statements
echo and
print are more or less the same. They are both used to output data to the
screen.
The
differences are small: echo has no return value while print has a return value
of 1 so it can be used in expressions. echo can take multiple parameters
(although such usage is rare) while print can take one argument. echo is
marginally faster than print.
The PHP echo
Statement
The echo
statement can be used with or without parentheses: echo or echo().
Display
Text
The
following example shows how to output text with the echo command (notice that
the text can contain HTML markup):
Example
<?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 output text and variables with the echo
statement:
Example
<?php
$txt1
= "Learn PHP";
$txt2
= "Omega.com";
$x
= 5;
$y
= 4;
echo
"<h2>$txt1</h2>";
echo
"Study PHP at $txt2<br>";
echo
$x + $y;
?>
The PHP
print Statement
The print
statement can be used with or without parentheses: print or print().
Display Text
The
following example shows how to output text with the print command (notice that
the text can contain HTML markup):
Example
<?php
print
"<h2>PHP is Fun!</h2>";
print
"Hello world!<br>";
print
"I'm about to learn PHP!";
?>
Display
Variables
The
following example shows how to output text and variables with the print
statement:
Example
<?php
$txt1
= "Learn PHP";
$txt2
= "Omega.com";
$x
= 5;
$y
= 4;
print
"<h2>$txt1</h2>";
print
"Study PHP at $txt2<br>";
print
$x + $y;
?>
