What is the correct syntax for echoing content in PHP and what potential pitfalls should be avoided?

When echoing content in PHP, the correct syntax is to use the `echo` statement followed by the content you want to display within quotes. It is important to avoid mixing PHP and HTML code within the echo statement, as this can lead to syntax errors or unexpected output. Additionally, make sure to properly escape any special characters or variables to prevent security vulnerabilities.
