How can debugging techniques be used to troubleshoot issues with echo statements in PHP code?

To troubleshoot issues with echo statements in PHP code, you can use debugging techniques such as printing out the variable values before the echo statement to ensure they contain the expected data. Additionally, you can use functions like var_dump() or print_r() to inspect the variable contents. If the echo statement is not displaying anything, check for syntax errors or incorrect usage of quotation marks. 

// Example PHP code snippet to troubleshoot echo statement issues
$variable = "Hello World";

// Use var_dump() to check the variable contents
var_dump($variable);

// Use print_r() to inspect the variable contents
print_r($variable);

// Check for syntax errors or incorrect usage of quotation marks
echo $variable;
