I hope this helps you . The code you put in viewDidLoad is executed once, when the view is loaded - it isn't triggered every time numbers is updated.
To implement what you need, you should make number an instance property, and add a didSet observer:
code :
class ViewController: UIViewController {
    var numbers: Int = 0 {
        didSet {
            if numbers == 5 {
                labelStatus.text = "Numbers variable is equal to 5! Hurray!"

With these it helps If the code you want to run after the if conditional is only one line you can omit the brackets. I find it confusing, so I don't do it but it is valid PHP.
So, what your code does works:
code :
if(empty($paged)) $paged = 1;
    $paged = 1; // semi-colon marks the end of the line
if(empty($paged)) $paged = 1; $othervar = 2;
   $paged = 1; 
   $othervar = 2;

it should still fix some issue The order of if and foreach in first case are wrong. See fixed and optimized variant:
code :
<?php $strRendersettings = ($this->settings)? 'settings' : 'view'; ?>
<?php if (count($this->data)): ?>
        $match = "";
            case "dev.domain.de":
                $match = "Deutsch";

            case "dev.domain.com":
                $match = "Englisch";

            case "dev.domain.fr":
                $match = "Franzoesisch";


        foreach ($this->data as $arrItem) {
            if ($arrItem['text']['new_docs_auswahl'] == $match){
                <li class="new_doc_home"><a href="" ><strong><?=$arrItem['text']['new_docs_titel']?>:</strong><br></a>
                        <p><a href="" ><?=$arrItem['text']['new_docs_Text']?></a></p>
<?php endif; ?>

I wish did fix the issue. Strings are compared using .equals rather than ==.
So replace if (StaffActivity.art == "F") with if (StaffActivity.art.equals("F")).
