在PHP的foreach循环中对数组进行排序

Question

I am looking at how to sort an array within a foreach loop to place my featured jobs to the top of the list.

The key and values are 'Featured Job' => 'Yes' or 'Featured Job' => 'No'

I am just checking to see if the key isset and then outputting a string saying 'Featured Job' - that part was easy. I am just unable to sort them to place the featured jobs at the top.

Here is my code, any hints or help would be appreciated:

    if( isset($v->customLovs) && !empty($v->customLovs->customLov) ) {
        $lovs = $v->customLovs->customLov;

      if( isset($lovs->label) )
        $lovs = array( $lovs );

      foreach( $lovs as $lov ) {
        switch( $lov->label ) {
          case "Position":
            $position = $lov->criteria->criterion->label;
            break;
          case "Town or City":
            $townOrCity = $lov->criteria->criterion->label;
            break;
          case "Featured Job":
            $fjob = $lov->criteria->criterion->label;
            break;                
        }
      }
    }

And here is the output:

<h2><?php echo $position;?></h2>
<?php if ( isset($fjob) ) : ?>Featured Job<?php endif; ?>
<?php echo $townOrCity;?>

My feeble attempt to cure this was like so:

$lovs = usort($lovs);

I can only assume that I need to target the $fjob somehow?

You can look up php documentation on sorting arrays. you can create a date key and sort by the date. http://php.net/manual/en/array.sorting.php
