In PHP, the echo
and print
statements are used to output text to the browser or server console. Both of these statements are used frequently in PHP programming. In this response, I will explain how to use both statements, and provide code samples to illustrate their usage.
PHP echo Statement
The echo
statement in PHP is used to output text to the browser or server console. It can be used to output any valid HTML, CSS, or JavaScript code, as well as plain text. The syntax for echo
is as follows:
echo "Text to output";
Here is an example of using the echo
statement to output text to the browser:
<?php
echo "Hello, World!";
?>
In the example above, the echo
statement outputs the text “Hello, World!” to the browser.
The echo
statement can also be used to output HTML code. For example:
<?php
echo "<h1>Welcome to my website!</h1>";
?>
In the example above, the echo
statement outputs an HTML heading element to the browser.
PHP print Statement
The print
statement in PHP is similar to the echo
statement, in that it is used to output text to the browser or server console. The syntax for print
is as follows:
print "Text to output";
Here is an example of using the print
statement to output text to the browser:
<?php
print "Hello, World!";
?>
In the example above, the print
statement outputs the text “Hello, World!” to the browser.
The print
statement can also be used to output HTML code. For example:
<?php
print "<h1>Welcome to my website!</h1>";
?>

Comparison between echo and print
While both echo
and print
statements are used to output text to the browser or server console, there are some differences between them.
echo
can take multiple arguments, separated by commas, whereasprint
can only take one argument.echo
does not have a return value, whereasprint
returns a value of 1.echo
is slightly faster thanprint
, since it does not return a value.
In most cases, it is recommended to use echo
over print
, since it is faster and can take multiple arguments. However, in situations where you need to capture the return value of the statement, print
can be useful.
Conclusion
In this article, we discussed the usage of echo
and print
statements in PHP programming, and provided code samples to illustrate their usage. While both statements are used for outputting text to the browser or server console, there are some differences between them. In general, echo
is the preferred statement to use, due to its speed and flexibility.
