Question

I am fetching some data from MySQL which I print into a table. I have a function to "X out" the content after the first 2 up to the last 2 digits of a number.

Now I am trying to use that function on every number in the row 'code' where the MySQL result is used='' before printing it.

Example: Data from mysql row 'code' and 'used':

code = 123456789 & used = 'n' result=123456789
code = 123456789 & used = '' result=12XXXXX89

This is my code for fetching, creating the table and also for the function to "X out" the middle digits:

<?php
$sql="SELECT * FROM table";
$result=mysql_query($sql);

// Count table rows
$count=mysql_num_rows($result);

?>

<?php function blankit($word) {
    return substr($word, 0,2). str_repeat("X",strlen($word)-4) . substr($word, strlen($word)-2,strlen($word));
} 
?>

<?php while($rows=mysql_fetch_array($result, MYSQL_ASSOC)){ ?>
<tr class="first">
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $rows['id']; ?></font></td>
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $rows['code']; ?></font></td>

<td><font face="Arial, Helvetica, sans-serif"><? echo $rows['date']; ?></font></td>
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $rows['ip']; ?></font></td>
<td class="tc"><input name="checkbox[]" type="checkbox" class="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> 


</tr>
<?php
}
?>

I'm not sure what this "used" variable is since it's not shown in your code sample, but I'm guessing it's in your mysql result. Here you go:

<?php
$sql="SELECT * FROM table";
$result=mysql_query($sql);

// Count table rows
$count=mysql_num_rows($result);

?>

<?php function blankit($word) {
    return substr($word, 0,2). str_repeat("X",strlen($word)-4) . substr($word, strlen($word)-2,strlen($word));
} 
?>

<?php while($rows=mysql_fetch_array($result, MYSQL_ASSOC)) {
$code = ($rows['used'] == '') ? blankit($rows['code']) : $rows['code']; ?>
<tr class="first">
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $rows['id']; ?></font></td>
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $code; ?></font></td>

<td><font face="Arial, Helvetica, sans-serif"><? echo $rows['date']; ?></font></td>
<td class="tc"><font face="Arial, Helvetica, sans-serif"><? echo $rows['ip']; ?></font></td>
<td class="tc"><input name="checkbox[]" type="checkbox" class="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> 


</tr>
<?php
}
?>
