PHP Printing Commands

Filed under: Computers, Technology — Paper Euphoria @ 12:00 am

Few other web development languages have done as much for web developers as PHP has. And in learning all the complexities of the language, web developers will be able to better become higher paid, more satisfied, and better prepared to make the next best web application. But taking baby steps in getting there is important: and the finer things such as knowing the difference between Echo and Print become clear.

Echo and Print are both commands used to display something to the browser. Both are used in similar structure, and both are identical in output. So what, then, is the use for having two commands that appear to do the exact same thing?

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.

Speed is a major concern in web applications. This holds true with the Print and Echo commands since it is logical to think that Print would cost more in resources to operate. This logic is actually true, although the differences in performance are so small that it isn’t even worth choosing one construct over the other solely based on performance.

So far the industry standard has been to use Echo, but it should be stressed that either command may be used at will. Echo seems to be the favorite as it is easier to type, not to mention it’s a fun word to say! Those who favor the Print command are usually older programmers, who are accustomed to using the command Print from other programming languages that are now considered archaic.

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

End the end, the battle between Echo and print is never ending. The trends do seem to show that Echo is much more popular, but with little reasons. The speed benefit is so small that it’s negligible- especially among faster systems that technology has produced where such effects go unnoticed. And because many books and online publications stick true to the Echo command, it’s likely we’ll only be seeing more of it as time goes on, and less of the fabled Print command that older generations have favored.
