How can conflicts between deactivating the Smarty Template Engine and existing PHP code be resolved effectively?

When deactivating the Smarty Template Engine in favor of existing PHP code, conflicts may arise due to differences in syntax and functionality. To resolve this effectively, you can gradually transition your Smarty templates to pure PHP code by replacing Smarty tags with equivalent PHP code. This involves converting variables, loops, conditionals, and other Smarty-specific constructs to standard PHP syntax.

// Example of converting a Smarty variable to PHP code
// Smarty: {$variable}
// PHP: <?php echo $variable; ?>
```

```php
// Example of converting a Smarty loop to PHP code
// Smarty: {foreach $items as $item}
// PHP: <?php foreach ($items as $item): ?>
//       <?php echo $item; ?>
//       <?php endforeach; ?>
```

```php
// Example of converting a Smarty conditional to PHP code
// Smarty: {if $condition}
// PHP: <?php if ($condition): ?>
//      <?php // code block ?>
//      <?php endif; ?>
