如何从$ cat_fields中排除$ row ['weight']

Question

Hi can you please help me to exclude a row from this peace of script:

<?php 
    if($ad_fields!="")  { 
     foreach ($ad_fields as $key => $value)
        {
          echo " <nobr><strong>&nbsp;&nbsp; ".$cat_fields[$key][0].": </strong>". 
      " ".$ad_fields[$key].$fld_dim[$key].$fld_dimd[$key].";<br /> </nobr> "; }} 
?>

This script echo all rows, how can I achieve that script doesn't call out for example $row['weight'], or $row['weight'] & $row['height']

Thanks

Your code-sample doesn't have a variable named $row , so I'm assuming you're referring to $cat_fields , $ad_fields , $fld_dim , or $fld_dimd (which all appear to have the same keys).

You can check the value of the $key in the foreach -loop. If it matches a value you don't want to display, use continue; to skip:

foreach ($ad_fields as $key => $value) {
    if (($key == 'weight') || ($key == 'height')) continue;

Alternatively, you can define an array of keys you want to skip and check with in_array() :

$skipKeys = array('weight', 'height');
foreach ($ad_fields as $key => $value) {
    if (in_array($key, $skipKeys)) continue;

The second option may be better if your list of keys-to-skip grows rather long.
