How Echo And Print Differ Written on July 30, 2008, by Internet Garner.
The Internet for webmasters just wouldn’t be the same without the language of PHP. PHP has given webmasters a long-lasting relationship with their websites, to manipulate it to best offer customers and Internet users what they need. But before becoming the master PHP expert, learning smaller details is important. And interestingly enough, many PHP developers don’t know the difference between Echo and Print.
Everyone in the PHP web development community is familiar with Echo and Print- two commands to output data to the screen. But what they may not know is that the two have the same output and similar structure- so why two commands for the same task?
The two language constructs Print and Echo differ because Echo does not return a value- although Print does. This is an odd thing to have, however, since a command used to output data to the screen will almost never need to return a value. In fact, even those who have been in the programming industry for years have probably never seen a good use of Print where Echo couldn’t follow.
While performance may be a big issue for PHP developers and their clients, the debate between Print and Echo is actually fairly meaningless. It is true that Print will take more system resources to use, but it is such a minimalistic amount that developers are recommended to choose the construct of their choice, regardless of speed issues.
When a PHP developer looks around at examples and scripts from others in the community, they will see that Echo is used much more often. This isn’t because of speed, as previously discussed, but because many think it easier to type and the keyword command is more appealing in design. The success of Echo has been compounded after many publishers make books and online resources that sport the term.
As a last note of worthiness, it should be made clear that if speed is an issue, more emphasis should be put on how the two commands are used. Repeatedly using either command where a programmer could simply concatenate a string or value together will waste system performance- and on a much more noticeable scale that the difference between returning a value or not. Thus, this subject should be addressed if anything in regards to speed.
Closing Comments
PHP development just wouldn’t be the same without fun debates such as the one just mentioned. But in reality, it really doesn’t matter which route is taken- so long as either language construct is used in a performance-based manner. Although Print may still have somewhat of a following today, as books and publishers start using Echo more often, it’s likely we’ll see a death to the Print command soon enough.
