In PHP there are two ways to “print” HTML markup, text, and variables, using print<\/code> and echo<\/code>. These are essentially interchangeable, though print<\/code> is slower, so best practice is to use echo<\/code>. “print” has a return value of 1 (so it can be used in expressions), while “echo” does not.\u00a0 print can take one argument, while echo can take multiple arguments.<\/p>\n

This code demonstrates how both echo and print work interchangeably. It also shows how to print a mixture of HTML markup, text, and variable data in PHP.<\/p>\n

<?php\r\n$txt1 = \"Using echo\";\r\n$txt2 = \"writephponline.com\";\r\n$x = 89;\r\n$y = 10;\r\n\r\necho \"<h3>\" . $txt1 . \"<\/h3>\";\r\necho $txt2 . \" is a good place to test PHP code.<br>\";\r\necho \"89 x 10 = \". $x * $y;\r\n\r\n$txt1 = \"Using print\";\r\n$txt2 = \"phptester.net\";\r\n$x = 45;\r\n$y = 8;\r\n\r\nprint \"<h3>\" . $txt1 . \"<\/h3>\";\r\nprint $txt2 . \" is a good place to test PHP code.<br>\";\r\nprint \"45 x 8 = \". $x * $y;\r\n?><\/pre>\n
Which yields:<\/p>\n
Using echo<\/h3>\n
writephponline.com is a good place to test PHP code.
\n89 x 10 = 890<\/p>\n
Using print<\/h3>\n
phptester.net is a good place to test PHP code.
\n45 x 8 = 360<\/p>\n
 <\/p>\n
This code demonstrates that echo can output multiple comma separated arguments:<\/p>\n
<?php\r\necho \"This \", \"string \", \"was \", \"made \", \"with multiple parameters.\";\r\n?><\/pre>\n
which yields:<\/p>\n
This string was made with multiple parameters.<\/pre>\n
However, print does not support multiple arguments. PHP will give an error when it sees a comma as an argument to print. For example:<\/p>\n
<?php\r\nprint \"This \", \"string \", \"was \", \"made \", \"with multiple parameters.\";\r\n?><\/pre>\n
yields:<\/p>\n
FATAL ERROR syntax error, unexpected ',' on line number 2<\/pre>\n
