Php echo/print

← Previous Next →


In PHP there are two basic ways to get output: echo and print.


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().
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."; 
?>

The following example shows how to output text and variables with the echo statement:

Example

<?php 
    $txt1 = "Learn PHP"; 
    $txt2 = "Breakinterview.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(). 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!"; 
?>

The following example shows how to output text and variables with the print statement:

Example

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