PHP echo and print Statements
With PHP, there are two basic ways to get output: echo and print.
In this tutorial we use echo
or 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
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
$txt1 = "Learn PHP";
$txt2 = "W3Schools.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
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
$txt1 = "Learn PHP";
$txt2 = "W3Schools.com";
$x = 5;
$y = 4;
print "<h2>" . $txt1 . "</h2>";
print "Study PHP at " . $txt2 . "<br>";
print $x + $y;
