<p>What are the specific steps to save content captured by ob_get_contents() to a file?</p>
</li>
<li></li>
<li>
<p>In PHP, ob_get_contents() is used to get the content from the current buffer.</p>
</li>
<li>
<p>If you enable output buffering using ob_start(), the page output is not directly sent to the browser,</p>
</li>
<li>
<p>but is stored in the buffer.</p>
</li>
<li>
<p>At this point, you can use ob_get_contents() to retrieve the content and save it to a file.</p>
</li>
<li></li>
<li>
<p>The specific steps are as follows:<br>
*/</p>
</li>
</ul>
<p>// 1. Start output buffering<br>
ob_start();</p>
<p>// 2. Output the content you want to capture, such as HTML, text, or program output<br>
echo "<h1>Welcome to the Output Buffering Example</h1>";<br>
echo "<p>This content will be captured and saved to a file.</p>";</p>
<p>// 3. Use ob_get_contents() to get the buffer content<br>
$content = ob_get_contents();</p>
<p>// 4. Close and clean the buffer<br>
ob_end_clean(); // Alternatively, use ob_end_flush(), but usually clean the buffer</p>
<p>// 5. Write the captured content to a file<br>
$file = 'output.html';<br>
file_put_contents($file, $content);</p>
<p>// 6. Output a success message (optional depending on your needs)<br>
echo "Content has been successfully saved to file: {$file}";</p>
