I was wondering...
I have this html for example generated dynamically with php:
<div>
<ul>
<li>Some content</li>
</ul>
</div>
This content will change always depend of the user input. So my question.. is possible to save the html generated after render the page in a $_SESSION variable and then return it in another page?
The only idea I have is:
//after query the sql
$_SESSION['html'][] = 'html content';
echo 'html content';
so after render all the page I will have all my html stored in the $_SESSION['html'] variable... but doesn't look good :S
<?php ob_start(); ?>
<div>
<ul>
<li>Some content</li>
<?php echo "<li>Some more content</li>"; ?>
</ul>
</div>
<?php
$_SESSION['html'][] = ob_get_contents();
ob_end_flush(); // or ob_end_clean();
The "ob" functions are for output buffering. They will capture in a buffer all output from echo statements or outside <?php ?> tags. After saving what's in the buffer with ob_get_contents, you can then send what's in the buffer with ob_end_flush or discard it with ob_end_clean.
There is nothing wrong to do that. Just change this
$_SESSION['html'][] = 'html content';
To
$_SESSION['html'] = 'html content';
and when you want to append something more do like this:
$_SESSION['html'] .= 'html content';
