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.

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?

Print is actually something more of a function, as it can be enclosed in brackets. Echo lacks this ability, but then again, there is almost never a need to do so. In reality, having this ability is something that even those who have seen it all in PHP likely won't need to make use of. This just adds more confusion to the topic than what was previously apparent.

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.

Even though speed should always be an issue, it's important to focus one's attention not on selecting a language construct for printing- but rather how they use it. Too often developers will use multiple Print or Echo calls, only to organize their code. But this can drastically degrade performance if enough calls are made, so it's recommended to choose the language construct of one's choice- but use it wisely.

Final Thoughts

Echo and Print will continue to confuse new developers that are learning PHP- this will never change. But as time wears on, it is more likely that the emphasis is going to be put on Echo. Already, there is a large emphasis place on using Echo simply because instructional resources do so. While Print may not be phased out, it will always be in the background for those who remember the "good old days" when the Print command was all a programmer had.
