Are there any specific best practices for handling special characters in PHP content to avoid issues with echo or variable assignment?

Special characters in PHP content, such as quotes, can cause issues with echo or variable assignment if not properly handled. To avoid problems, you can use escape characters (\) before special characters to ensure they are treated as literal characters rather than part of the code. This will prevent syntax errors and allow the content to be displayed or assigned correctly.

// Example of handling special characters in PHP content
$specialString = "This is a string with a special character: \"";
echo $specialString;
