Json返回字符

Question

When I am trying to echo json in php it returns \t . How I can remove them?

Here is my code:

            ob_start();
                $this->load->view('competition/template',$q);
                $content = ob_get_clean();
                $data['content'] = $content;

             echo json_encode($data);

And am getting:

</table>{"ok":1,"content":"<table>
   <tr>
\t    <td>Competitor name<\/td>
\t    <td><input type=\"text\" name=\"competitor_name[2]\" \/><\/td>
   <\/tr>
   <tr>
   <\/tr>
   <tr>
   <\/tr>
   <tr>
   <\/tr>
<\/table>"}

This is the template.php file:

 <table>
   <tr>
        <td><?php echo $this->__('Competitor name');?></td>
        <td><input type="text" name="competitor_name[<?php echo $id?>]" /></td>
   </tr>

</table>

After str_replace or preg_repalce, am getting:

{"ok":1,"content":"<table>   <tr>    <td>Competitor name<\/td>    <td><input type=\"text\" name=\"competitor_name[1]\" \/><\/td>   <\/tr> <\/table>"}

Now my problem is \.

Thank you.

Ok I found the anwser. Here it is:

 $content = preg_replace("@[\|\
|\\t|\\/|\\\"]+@", "", $content);

But am not sure why I was getting this problem .

Remove un-necessary whitespace from your content using:

$content = preg_replace("@[\|\
|\\t]+@", "", $content);
$data['content'] = $content;
echo json_encode($data);
