In PHP is there a built-in function to replace this foreach loop?












0














In order to integrate icons into the navbar I use key=>value arrays to store a file name with an icon tag. In the navbar I use a foreach loop to build dropdown menus or index into an array for an individual navlink. This also allows to dynamically build and alter the dropdown menus very easily.



$homepage = array(
'index.php'=>'<i class="fa fa-home"></i>'
);
$guestpages = array(
'createaccount.php'=>'<i class="fa fa-university"></i>',
'login.php'=>'<i class="fa fa-sign-in"></i>'
);
$logout = array(
'logout.php'=>'<i class="fa fa-sign-out"></i>'
);
$pages = array($homepage,$guestpages,$logout);


I also parse the URL to determine what page the client is viewing.



$pagename = basename($_SERVER['PHP_SELF']);


And in order to associate the parsed URL with the appropriate icon tag from the $pages array, I currently use a nested foreach loop:



foreach ($pages as $pagearray) {
foreach ($pagearray as $page => $icon) {
if($pagename == $page) {
$pageicon = $icon;
}
}
}


And what I'd like to do instead is something like this:



$pageicon = $pages[?][$pagename];


Does a similar alternative solution exist?

  • Why the three separate arrays? If you'd just have $pages = ['index.php' => ...], you could simply do $pages[basename($_SERVER['PHP_SELF'])]

Since your pagename must be unique, you can build your array in a single dimension, like this:



$pages = [
'index.php'=>'<i class="fa fa-home"></i>',
'createaccount.php'=>'<i class="fa fa-university"></i>',
'login.php'=>'<i class="fa fa-sign-in"></i>',
'logout.php'=>'<i class="fa fa-sign-out"></i>',
];


Then just use:



$icon = $pages[basename($_SERVER['PHP_SELF'])] ?? '<some default>';


[Edit] Alternatively, you can use array_merge() to combine your arrays:



$pages = array_merge($homepage, $guestpages, $logout);
