PHP Echo and Print Statements
|
|
echo and print are basically the same. Both are used to transmit data to a screen.The differences are minor: echo has no return value, whereas print has one return value therefore it is able to be utilized in expressions. echo can accept multiple parameters (although it is uncommon to use this feature) and print can accept only one argument. echo is slightly quicker than print.
In PHP, echo and print can both be used to send data or text to the browser on the web or to the client. They are used most often to display information and variables or HTML markups in PHP scripts.
In PHP there are two main ways to the output you want: echo and print..
In this tutorial, we will use echo or print in nearly every instance. This chapter provides an additional explanation of the two statements that output.

Echo:
-
echo is a type of language and not a function meaning that you can utilize it without parentheses like echo "Hello, World! ";.
-
It is possible to produce multiple string expressions that are separated by spaces:
echo "Hello", " World";.
-
echo is typically more efficient and is used more often within PHP scripts.
-
No Parentheses Needed: Think of echo as a friendly helper that can show stuff on the screen. The cool part is, you don't need to put parentheses (those () things) around what you want to show. Just say echo, and then the message or stuff you want to display.
-
Example:
echo "Hello, World!"; – This shouts "Hello, World!" on the screen.
-
Show More Together: echo is like a DJ for text. It can display lots of things all at once. You just separate them with commas.
-
Example:
echo "Hello", " ", "World!"; – This spells out "Hello World!" on the screen.
-
It is possible to use the echo statement can be used in conjunction with as well without: echo or echo().
Display Text
The following example illustrates what you can output as text using echo. echo command (notice that the text could be a part of HTML markings):
Example:
"""
echo "Hello world!
";
echo "I'm about to learn PHP!
";
echo "This ", "string ", "was ", "made ", "with multiple parameters.";
"""
Display Variables
The following example illustrates what you can do to print text or variables using an echo statement:
Example:

Print :
-
print is an application, which is why it requires parentheses similar to print("Hello, World! ");.
-
It is able to output only the same value one at a single time and always returns 1 which is a valid value to use in expressions.
-
print is a little less efficient in comparison to echo due to the fact that it's part of a function.
-
Needs Parentheses: Print is also like a text displayer, but it's a bit pickier. It wants everything inside parentheses, like print("Hello, World!");. It's like saying, "Print this, please!"
-
Example:
print("Hello, World!");
//It politely asks, and "Hello, World!" appears.
-
One Thing at a Time: Print can only show one thing at a time. If you want to show more, you need to ask it multiple times.
-
Example:
print("Hello, ");
print("World!");
//This also displays "Hello World!" but in two steps.
- Print statements are a way to print.
print statement can be used in conjunction with and without the parentheses print or print().
So, in a nutshell, echo is quick and easy, while print is more polite but a bit slower. Most PHP folks prefer echo, but print is useful when you have to be extra polite and want to use the result in something else. Both are your friends for showing off text in PHP!
Display Text
The following example demonstrates how to print text using the print command (notice that the text could include HTML marksup):
Example:
"""
print "Hello world!
";
print "I'm about to learn PHP!";
"""
Display Variables
The following example illustrates how to output text or variables by using the print statement:
Example:
|
Certainly! Yes! Although they share a common use, there are a few distinctions between the two.
|
Echo |
Print |
| Return Value: |
echo doesn't have an return value, so it can't be used in expressions, or allocated to variables.
|
print returns an amount of 1 which makes it a real function. It can be utilized in expressions, and even assigned to variables.
|
| Syntax: |
echo is a word-processing construct and doesn't require parentheses. It can be used to echo "Hello, World! ";.
|
print is a function of PHP and employs parentheses just like a normal method: print("Hello, World! ");.
|
| Speed: |
echo is usually quicker over print because it's a linguistic construct and doesn't need the use of a function.
|
echo is usually slower than print because it's construct and need the use of a function.
|
| Number of Arguments: |
echo can accept multiple arguments separated by commas. echo "Hello", "World";.
|
print is a single argument.
|
| Usability in HTML: |
echo is commonly employed to create HTML content because it doesn't require parentheses, and is much more concise in this regard.
|
print is not widely utilized in HTML output because of its similar syntax to a function.
|
| Error Handling: |
echo isn't able to give a value, and therefore it is not able to find mistakes.
|
print returns 1 on successful print and 0 on failure providing simple error management.
|
| Historical Context: |
echo has been a part of PHP since the beginning of its development and is regarded as a fundamental PHP language construct.
|
print is also available in PHP however it is not as widely employed in comparison with echo that is more widely used.
|
In the real world, developers use echo because of its ease of use and superior performance. It is true that printing can be useful if you have to test an expression as well as show its value, since it returns one and is able to be used in larger expressions.

In the realm of PHP scripting, the decision between 'echo' and might seem like a minor thing however, it could dramatically affect how you present data and text to your customers. "Echo," the flexible tool that works with both is distinguished by its ease of use and effectiveness. It doesn't require parentheses which makes it extremely user-friendly and it is able to show multiple items at a move, which makes it a popular choice for developers. "Print," is the opposite, and is a polite substitute. It insists on using parentheses to indicate a respectful request for output, but it only displays one thing at one time. It has an advantage in that it always returning '1 that can be useful in integrating its output into more complex expressions.
In terms of performance, 'echo' has an advantage over print and is the preferred choice for developers who are speed conscious. It's not a surprise that 'echo' has more attention because of its ease of use and scalability. However, print has its own niche applications, especially where a specific value has to be displayed and used in the context of a larger calculation.
In the end both echo and print serve the same basic purpose of providing information for the end user. The decision to choose between them depends on individual preferences and the specific requirements of your project. PHP developers are confident in using these tools to create appealing and dynamic web pages, no matter if they prefer the slickness of echo or the elegant beauty of printing.' In the echo print vs. print battle, keep in mind that you have two trusted allies within your PHP toolkit that are that are ready to assist you in communicating effectively with your viewers.
