I have a 4 level multidimensional array, and want to check if a string exists in the 4th level.
I want something like in_array(), but looking into the deepest level. I can’t work out how to do it.
I’m already in a foreach on the first level of the array, so am searching 3 levels down.
It’s hard to explain without giving a whole load of code.
It’s for a menu, where I want to apply an id to the current section.
This is the site, so you can see the menu and its html.
Here is the array that makes the menu:-
$pg = basename($_SERVER['PHP_SELF']);
$menuarr = array(
'home' => array(
'title' => 'Homepage',
'icon' => 'home',
'target' => '/',
'sub' => null
),
'war' => array(
'title' => 'Burton at War',
'icon' => 'swords',
'target' => '#war',
'sub' => array(
array('tankramp.php', 'The Tank Ramp'),
array('location.php', 'Location'),
array('thesite.php', 'The Site'),
array('rollofhonour.php', 'Roll of Honour'),
array('canadians.php', 'The Canadians')
)
),
'heritage' => array(
'title' => 'Burtons Heritage',
'icon' => 'heritage',
'target' => '#heritage',
'sub' => array(
array('shipping.php', 'Shipping at Burton'),
array('shipping.php?content=list', 'The Ship List'),
array('brickworks.php', 'The Brickworks'),
array('artefacts.php', 'Artefacts'),
array('burtonwmc.php', 'Burton WMC'),
array('history_cal.php', 'History Calendar')
)
),
'events' => array(
'title' => 'BSHG Events',
'icon' => 'calendar',
'target' => '#events',
'sub' => array(
array('calendar.php', 'Events Calendar'),
//array('funday.php', 'BSHG Fun Day'),
array('beer-fest.php','Burton in Beer'),
array('raftrace.php', 'Raft Race'),
array('past-events.php', 'Past Events')
)
),
'interview' => array(
'title' => 'Interviews',
'icon' => 'bubble',
'target' => '#interview',
'sub' => array(
array('john_porteous.php', 'John Porteous'),
array('dave_gibb.php', 'Dave Gibb'),
array('sally_robinson.php', 'Sally Robinson'),
array('edna_lawn.php', 'Edna Lawn')
)
),
'about' => array(
'title' => 'About Us',
'icon' => 'info',
'target' => '#about',
'sub' => array(
array('about.php', 'About BSHG'),
array('contact.php', 'Contact Us'),
array('ourwork.php', 'Our Work'),
array('media.php', 'In the Media'),
array('links.php', 'Thanks & Links'),
array('sitemap.php', 'Sitemap')
)
)
) ;
This is the part of the code that writes the main top-level menu, the sub-menus come after. I basically want to find if the page name ($pg) is in the menu section, and apply the currmen id (current menu) to the section where the current page belongs to.
foreach( $menuarr as $key => $value) { // Render the main menu
if( in_array($pg, $value['sub']) ) { $mid = ' id="currmen"' ; }
else { $mid = '' ; }
echo '
<li>
<a class="sec" href="'.$value['target'].'" title="'.$value['title'].'"'.$mid.'>
<img src="images/'.$value['icon'].'.svg" width="50" height="50" alt="'.$value['title'].'">
<span>'.$value['title'].'</span>
</a>
</li>' ;
} // end foreach top level
I know that in_array line is wrong, but I’m asking how it should be. The rest of it works fine.
