How can debug outputs affect the functionality of PHP code, specifically in if-else conditions?

Debug outputs in PHP code can affect the functionality of if-else conditions by inadvertently outputting content before the condition is evaluated, leading to unexpected behavior or errors. To prevent this issue, debug outputs should be placed strategically within the code to ensure they do not interfere with the logical flow of if-else conditions. 

<?php
// Incorrect placement of debug output
echo "Debug output before if-else condition";

$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is less than or equal to 5";
}
?>
```

To fix the issue, move the debug output to a location that does not disrupt the evaluation of the if-else condition:

```php
<?php
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is less than or equal to 5";
}

// Correct placement of debug output
echo "Debug output after if-else condition";
?>
