如何使用PHP删除mysql_query的最后一个逗号？

Question

I have a mysql_query where I need to strip the last comma behind the last item(s).

How can I do that?

Here is the code snippet:

mysql_query('INSERT INTO `items` (itemName, itemDescription  ) VALUES ("' . $form_input0 . '","' . $form_input1 . '",);');

The part that gives the "form_input" is what I am concerned with

"' . $form_input1 . '",

That trailing comma is what I need to strip ...

Some folks have suggested that I edit the question and include all of the code I am working with. Maybe it will help ...

<?php

$host = '%id=server%';
$user = '%id=username%';
$password = '%id=password%';

$link = mysql_connect($host, $user, $password);

$selected = mysql_select_db('%id=database%', $link);

if(!isset($_POST['text-input']))

?>



    <form method="post">
        %slice%
        <input type="submit" value="Submit" />
    </form>
    %[if !edit]%



<?php
%[repeat items]%
$form_input%id=repeatIndex% =  $_POST['element-%id=repeatIndex%'] ;

%[endrepeat]%

mysql_query('INSERT INTO `%id=table%` (%[repeat items]%  %[endif]%%html="Edit Me"%%[if !edit]% %[endrepeat]% ) VALUES (%[repeat items]%"' . $form_input%id=repeatIndex% . '",%[endrepeat]%);');

?>
%[endif]%

Answer 1

As hookman has rightly mentioned in comments mysql extension is depreciated and should not be used.

EDIT Now that you code is edited. As you mentioned I don't know the API but I do know one possible solution.

• Assign your query to a variable.
• Replace the last part of the query so that the , is removed.

Try:

...
%[endrepeat]%

$query = 'INSERT INTO `%id=table%` (%[repeat items]%  %[endif]%%html="Edit Me"%%[if !edit]% %[endrepeat]% ) VALUES (%[repeat items]%"' . $form_input%id=repeatIndex% . '",%[endrepeat]%);';
$query = preg_replace('/,\);$/',');',$query);
mysql_query($query);

....

The preg_replace will simply edit your query, so that any string that has ,); at the end of it, will be replaced with ); . You can use that with other queries, just figure out how to transform them with RegEx.

I understand that your markup language (whatever it is that you use) has limitations that could prohibit you to do this utilizing it's standard functionality - in this case 'manually' (with regex or otherwise replace) editing the string is your only option (that or parsing it somehow).

Alternatively, this might work:

...

%[repeat items]%
$values = array(
    mysql_real_escape_string($form_input%id=repeatIndex%),
    mysql_real_escape_string($form_input%id=repeatIndex%)
);
%[endrepeat]%
$query = 'INSERT INTO `%id=table%` (%[repeat items]%  %[endif]%%html="Edit Me"%%[if !edit]% %[endrepeat]% ) VALUES (' . "'" . implode("','", $values) . "')";

...

Answer 2

$sql = str_replace(',);', ');', $sql);

But i would do it like this:

$values = array(
    $form_input0,
    $form_input1
);
$sql = sprintf(
    'INSERT INTO `items` (itemName, itemDescription  ) VALUES ("%s")',
    implode('", "', $values)
);
$result = mysql_query($sql);
