php does not load scripts when i don't do a var_dump

Question

I build css links with a function but if I don't do a var_dump on the end, the css will not work. What am I missing or not seeing?

The code:

private function buildCssLinks(){
    $files  =   $this->findFiles(dirname(dirname(__FILE__))."/css","css");

    foreach ($files as $id)
    {
        $pathInfo   =   pathinfo($id);
        $fileName   =   $pathInfo['basename'];

        $files[] = '<link rel="stylesheet" type="text/css" href="css/' . $fileName . '">';
    }
    return implode("",$files);
}

returns

1st return

but when I add a var dump in my code

    private function buildCssLinks(){
    $files  =   $this->findFiles(dirname(dirname(__FILE__))."/css","css");

    foreach ($files as $id)
    {
        $pathInfo   =   pathinfo($id);
        $fileName   =   $pathInfo['basename'];

        $files[] = '<link rel="stylesheet" type="text/css" href="css/' . $fileName . '">';
    }
    var_dump($files);
    return implode("",$files);
}

the 2nd return

2nd return

the code that calls the functions __construct

  public function __construct($header, $body, $footer)
{
    $this->header   =   $header;
    $this->body     =   $body;
    $this->footer   =   $footer;


    $this->buildHeader();
    $this->buildBody();
    $this->buildFooter();

    $js     =   $this->buildJsLinks();
    $css    =   $this->buildCssLinks();
    $this->header   =   $css;
    $this->footer   =   $js;
}

I get the feeling you need to echo buildCssLinks().

Your buildCssLinks is returning the html. But you must then put it into your html somehow. Perhaps

$css = $this->buildCssLinks();
$this->header .= $css;

or more likely you need to buildCssLinks first and pass that into header build:

$this->css = $this->buildCssLinks();
$this->buildHeader();  // within buildHeader echo your this->css

what does the implode function then ?

WEBjuju Over a year ago

it takes all of the elements of an array and concatenates them with the first argument to implode (which in your case is empty). so array(1,2,3) imploded is "123" and implode(",", array(1,2,3)) is "1,2,3", yo.

i added

$js     =   $this->buildJsLinks();         $css    =   $this->buildCssLinks();         $this->header   =   $css;         $this->footer   =   $js;
