Deleting printed content in PHP mysql

Deleting printed content in PHP mysql

I'm creating a site to upload content and I want the user to be able to
delete content on their Edit page. The following code is what I have
echoed after the user inputs their content
`<div id="content_review">
<?php
$q_getRev = "SELECT * FROM REVIEWS ORDER BY RID DESC";
$r_getRev = mysql_query($q_getRev,$connection);
$n_getRev = mysql_num_rows($r_getRev);
for($i=0; $i<$n_getRev; $i++){
echo '<img class="poster" src="'.mysql_result($r_getRev,
$i, 'PREVIEW_IMG').' " />';
echo '<div class="title">'.mysql_result($r_getRev, $i,
'TITLE').'</div><br/>';
echo '<div class="reviews">'.mysql_result($r_getRev, $i,
'REVIEW').'</div>';
echo '<div><img src=image/x.png
id="delete">'.mysql_result($_delRev, $i,
'REVIEW').'</div>';
}
?>`
I want the user to be able to delete content that was previously printed
in PHP. I'm not entirely sure how to proceed to make the following line
delete content from my REVIEW column from mysql (the following line
appears as a delete button next to the already printed content)
echo '<div><img src=image/x.png id="delete">'.mysql_result($_delRev, $i,
'REVIEW').'</div>';
