If you view the source of your HTML code you will see the HTML code you inserted using the echo function displayed just as you intended. Considerations with HTML Inside PHP Let’s discuss some pitfalls commonly seen with the practice of inserting HTML inside PHP.

Truly professional code follows three general guidelines: ❑ Consistency: Blocks of well-written code always look the same and have the same indents and ways of coding, such as syntax shortcuts that use bracket placement and formatting styles consistently throughout the program. The great thing about PHP is that it really doesn’t care about tabs or indents, so you are free to create a style all your own, one that works best for you. 35 Chapter 2 In addition, while there may be more than one syntax for accomplishing the same goal, good coders will be consistent throughout their code with whichever method they choose.
