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.

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?

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.

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.

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

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.
