php function to get page title

Question

I want to get my website page title through a function

First I get the Page Name from a function...

function pagetitle() {
global $th, $ta, $tp, $ts, $tc; // <---- Getting the variable value from outside function
global $bl, $qt;
$tit = ucfirst(pathinfo($_SERVER['PHP_SELF'], PATHINFO_FILENAME));
if($tit == "Index") {
    echo $th;
}
elseif($tit == "About-us"){
    echo $ta;
}
elseif($tit == "Projects"){
    echo $tp;
}
elseif($tit == "Services"){
    echo $ts;
}
elseif($tit == "Contact-us"){
    echo $tc;
}
elseif($tit == "Blog"){
    echo $bl;
}
elseif($tit == "Quotation"){
    echo $qt;
}

}

Then I tried to get the page title in the format of PageName | PageTitle or PageTitle | PageName...

function getOrg_title(){
$tit = "";
$block = " | ";
global $sl;
$org = $sl['app_org'];
if($sl['title_before'] === 'yes'){
    $tit = $org.$block.\pagetitle(); //<----- This should be like "Raj | This is my website"
}  else {
    $tit = \pagetitle().$block.$org; //<----- This should be like "This is my website | Raj"
}
echo $tit;
}

But not happening...

$tit = $org.$block.\pagetitle(); //<----- Output is "This is my websiteRaj |"

And

$tit = \pagetitle().$block.$org; //<----- Output is "This is my website | Raj"

What should I do ?

Answer 1

You expect pagetitle() to return the page's title, but instead in your code you use echo.
echo will print out the title to the client rather than return it to the caller.

So change you echo $...; to return $...; and do echo pagetitle(); whereever you use it directly.

If this can not be done, you could extend your function to

pagetitle($echo = true)
{
    // ...
    if(/* ... */) {
        $ret = $th;
    } elseif(/* ... */) {
        $ret = ...;
    } elseif(/* ... */) {
        $ret = ...;
    }
    // And so on ...

    if($echo)
        echo $ret;

    return $ret;
}

Now in your wrapper function call pagetitle(false) to prevent the echo and still get the title from it.

About the backslash: \pagetitle()
The backslash is the namespace separator. Since you are not using namespacing here, all functions will be on the root namespace.
In this case - if you are using PHP 5.3 or above - you can use it or leave it out.
