如何替换mysql数据库内容数组中的文本

Question

im trying to get rid of unneccesary text in my database content.My code looks like this:

if(mysql_num_rows($result)) 
  $items[] = array();

while($row = mysql_fetch_assoc($result)) {
   $items[] = array('id' => $row['id'], 'cat' => $row['cat'], 'type' => $row['type'], 'name' => $row['name'], 'sub_title' => $row['sub_title'], 'display_date' => $row['display_date'], 'slug' => $row['slug'], 'ticket_url' => $row['ticket_url'], 'status' => $row['status'], 'content' => $row['content'], 'display_until' => $row['display_until'], 'photo' => $row['photo'], 'thumb' => $row['thumb']);

    $removals = array('\n','\r','\t','<\/div>\r\n');
    $spaces = "";
    $parsedText = str_replace($removals, $spaces, $items);
}
echo json_encode(array('events'=>$items));

And the content then displays like this:

{"events":[[],{"id":"66","cat":"9","type":"2","name":"Oileán - A Celebration of the Blasket Islands","sub_title":"National Folk Theatre","display_date":"Tues 4th - Thurs 6th May at 8.30pm","slug":"This production celebrates life on the Blasket Islands in times past, exploring the way of life of the islanders and their spirit of survival.

","ticket_url":"","status":"1","content":" \\r\\n\\tPresented by the members of the National Folk Theatre of Ireland</strong>, this production celebrates and explores Blasket Island living while also challenging our own notions of identity as contemporary islanders. </div>\\r\\n \\r\\n\\t </div>\\r\\n \\r\\n\\tPremiered in 2003, Oileán</strong></em> marked the 50th</sup> anniversary of the departure of the Blasket Islanders to the mainland.

2 things

if(mysql_num_rows($result)) 
  $items = array(); // not $items[], that would set the first item as an array

while($row = mysql_fetch_assoc($result)) {

   $removals = array("\n","\r","\t","<\/div>\r\n");
   $spaces = "";

   $items[] = array(
        'id' => $row['id'],
        'cat' => $row['cat'],
        'type' => $row['type'],
        'name' => $row['name'],
        'sub_title' => $row['sub_title'],
        'display_date' => $row['display_date'],
        'slug' => $row['slug'],
        'ticket_url' => $row['ticket_url'],
        'status' => $row['status'],

        // replace the content here
        // youll want to use preg_replace though otherwise youll end up with multiple </div>'s
        'content' => str_replace( $removals, $spaces, $row['content'] ),

        'display_until' => $row['display_until'],
        'photo' => $row['photo'],
        'thumb' => $row['thumb']
    );


}
echo json_encode(array('events'=>$items));
