わかりました、これが説明された解決策です：

$arr = array( 0=>'name', 1=>'Work Experience', 2=>'', 3=>'company', 4=>'location' );
var_export($arr); echo '<br/>';
$search = "Work Experience";
$arrkey = false;
foreach($arr as $key=>$value){ // set variables and advance internal pointer
    echo "inside foreach $key => $value <br/>";
    if( $value == $search ) {
        echo $key;
        echo $arrkey = key($arr); // internal php pointer already points to next array key
        break;
    }
}
if ($arrkey!=false && empty($arr[$arrkey])) {
    $arr[$arrkey] = 'Work Experience Max';
}
echo '<br/>'; var_export($arr);

便利なリンク：foreach、key、empty。お役に立てば幸いです。:-)
