PHP Echo and Print Statements

❮ Previous Next ❯

PHP is a widely-used, open-source programming language that is particularly suited for web development. One of the most basic elements of PHP programming is the ability to output text to a web page. This is done using the echo and print statements.

We will take a closer look at both of these statements and discuss the similarities and differences between them.

Echo Statement

The echo statement is used to output one or more strings in PHP. It can be used with or without parentheses and can take multiple arguments, separated by commas.

Here is an example of how to use the echo statement to output a simple string:

echo "Hello, World!";

It is also possible to use variables with the echo statement.

Here is an example of how to use a variable with the echo statement:

$name = "John Doe";
echo "Hello, " . $name . "!";

Print Statement

The print statement is similar to the echo statement in that it is used to output strings in PHP. However, the print statement can only take one argument and always returns a value of 1.

Here is an example of how to use the print statement to output a simple string:

print "Hello, World!";

Like the echo statement, it is also possible to use variables with the print statement.

Here is an example of how to use a variable with the print statement:

$name = "John Doe";
print "Hello, $name!";

Similarities and Differences

One of the main similarities between the echo and print statements is that they are both used to output strings in PHP. However, there are also some key differences between the two statements.

The echo statement can take multiple arguments and does not return a value, whereas the print statement can only take one argument and always returns a value of 1.

Additionally, the echo statement can be slightly faster than the print statement because it does not return a value.

Another difference between the two statements is the way that they handle variables. With the echo statement, variables must be concatenated using the . operator, whereas with the print statement variables can be included directly within the string.

Takeaways

In conclusion, the echo and print statements in PHP are similar in that they are both used to output strings to a web page.

However, there are some key differences between the two statements, such as the number of arguments they can take and the way they handle variables.
