PHP 5 echo and print Statements
In PHP, there are two basic output methods: echo and print.
In this chapter, we will discuss the usage of these two statements in detail and demonstrate how to use echo and print with examples.
PHP echo and print Statements
Differences between echo and print:
echo- Can output one or more stringsprint- Can only output one string, and its return value is always 1
Tip: echo is faster than print. echo has no return value, while print has a return value of 1.
PHP echo Statement
echo is a language construct, so you can use it with or without parentheses: echo or echo().
Displaying Strings
The following example demonstrates how to use the echo command to output a string (the string can contain HTML tags):
Example
<?php
echo "<h2>PHP is fun!</h2>";
echo "Hello world!<br>";
echo "I want to learn PHP!<br>";
echo "This is a string, using multiple parameters.";
?>Displaying Variables
The following example demonstrates how to use the echo command to output variables and strings:
Example
<?php
$txt1 = "Learning PHP";
$txt2 = ".COM";
$cars = array("Volvo", "BMW", "Toyota");
echo $txt1;
echo "<br>";
echo "Learning PHP at $txt2";
echo "<br>";
echo "My car brand is {$cars}";
?>PHP print Statement
print is also a language construct, and you can use parentheses or not: print or print().
Displaying Strings
The following example demonstrates how to use the print command to output a string (the string can contain HTML tags):
Example
<?php
print "<h2>PHP is fun!</h2>";
print "Hello world!<br>";
print "I want to learn PHP!";
?>Displaying Variables
The following example demonstrates how to use the print command to output variables and strings:
Example
<?php
$txt1 = "Learning PHP";
$txt2 = ".COM";
$cars = array("Volvo", "BMW", "Toyota");
print $txt1;
print "<br>";
print "Learning PHP at $txt2";
print "<br>";
print "My car brand is {$cars}";
?>
