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:
<?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 = "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:
<?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 = "W3Schools.com"; $x = 5; $y = 4; print "<h2>" . $txt1 . "</h2>"; print "Study PHP at " . $txt2 . "<br>"; print $x + $y; ?>
