What steps can be taken to troubleshoot and resolve issues with PHP code that is not producing the expected output?

Issue: When PHP code is not producing the expected output, it may be due to syntax errors, logic errors, or incorrect variables being used. To troubleshoot and resolve these issues, you can start by checking for syntax errors using a syntax checker tool or by reviewing the code for any typos. Next, you can use debugging techniques such as printing out variables or using var_dump() to see the values at different points in the code. Finally, you can review the logic of the code to ensure that it is correctly structured to produce the desired output. 

// Example PHP code snippet to troubleshoot and resolve issues with code not producing expected output

// Step 1: Check for syntax errors
// Use a syntax checker tool or review the code for typos
// Example: missing semicolon at the end of a line
$variable = "Hello World"

// Step 2: Use debugging techniques
// Print out variables or use var_dump() to see values
// Example: print out the value of a variable
$number = 10;
echo $number;

// Step 3: Review the logic of the code
// Ensure that the code is correctly structured to produce the desired output
// Example: incorrect comparison operator
if ($number = 10) {
    echo "Number is 10";
} else {
    echo "Number is not 10";
}
