How to create an ARRAY in an ARRAY - php

Question

I have this code (created from the admin side) in my wordpress Database postmeta table.
a:28:{s:12:"featuredItem";s:1:"0";s:10:"headerType";s:5:"image";s:11:"headerImage";s:60:"https://rocks---.de/wp-content/uploads/2018/08/IMG_2051.jpg";s:16:"headerImageAlign";s:10:"image-left";s:3:"map";a:7:{s:7:"address";s:6:"Goslar";s:8:"latitude";s:10:"51.9059531";s:9:"longitude";s:18:"10.428996299999994";s:10:"streetview";s:1:"0";s:9:"swheading";s:2:"90";s:7:"swpitch";s:1:"5";s:6:"swzoom";s:1:"1";}s:9:"telephone";s:4:"0221";s:19:"telephoneAdditional";a:3:{i:0;a:1:{s:6:"number";s:12:"111111111111";}i:1;a:1:{s:6:"number";s:13:"2222222222222";}i:2;a:1:{s:6:"number";s:13:"3333333333333";}}s:5:"email";s:20:"goslarEmail#email.de";s:9:"showEmail";s:1:"1";s:15:"contactOwnerBtn";s:1:"1";s:3:"web";s:27:"https://musicheadquarter.de";s:12:"webLinkLabel";s:17:"Label of the Link";s:19:"displayOpeningHours";s:1:"1";s:18:"openingHoursMonday";s:2:"12";s:19:"openingHoursTuesday";s:2:"12";s:21:"openingHoursWednesday";s:2:"12";s:20:"openingHoursThursday";s:2:"12";s:18:"openingHoursFriday";s:2:"12";s:20:"openingHoursSaturday";s:2:"12";s:18:"openingHoursSunday";s:2:"12";s:16:"openingHoursNote";s:26:"Text zu den Öffnungsziten";s:18:"displaySocialIcons";s:1:"1";s:26:"socialIconsOpenInNewWindow";s:1:"1";s:11:"socialIcons";a:2:{i:0;a:4:{s:5:"image";s:0:"";s:4:"icon";s:18:"fa-facebook-square";s:9:"iconColor";s:7:"#00FF00";s:4:"link";s:22:"http://rocks---.de";}i:1;a:4:{s:5:"image";s:0:"";s:4:"icon";s:12:"fa-instagram";s:9:"iconColor";s:7:"#00FF00";s:4:"link";s:20:"https://rocks---.de";}}s:14:"displayGallery";s:1:"1";s:7:"gallery";a:3:{i:0;a:2:{s:5:"title";s:6:"Bild 1";s:5:"image";s:60:"https://rocks---.de/wp-content/uploads/2019/01/IMG_8797.jpg";}i:1;a:2:{s:5:"title";s:6:"Bild 2";s:5:"image";s:60:"https://rocks---.de/wp-content/uploads/2019/01/IMG_8443.jpg";}i:2;a:2:{s:5:"title";s:6:"Bild 3";s:5:"image";s:60:"https://rocks---.de/wp-content/uploads/2018/08/IMG_8545.jpg";}}s:15:"displayFeatures";s:1:"1";s:8:"features";a:2:{i:0;a:3:{s:4:"icon";s:0:"";s:4:"text";s:15:"Feature Titel 1";s:4:"desc";s:28:"Feature Titel Beschreibung 1";}i:1;a:3:{s:4:"icon";s:0:"";s:4:"text";s:15:"Feature Titel 2";s:4:"desc";s:28:"Feature Titel Beschreibung 2";}}}
Now I tried to create the code for this ARRAY or what it is called. Everything works fine, exept the ARRAY in an ARRAY thing. Like, the list of social icons, image galelry and telephone numbers.
This is what I have so far:
$data = array(
'subtitle' => 'Utertitel',
'featuredItem' => '0',
'headerType' => 'image',
'headerImage' => 'https://rocks---.de/wp-content/uploads/slide3___beach-2179183_1920.jpg',
'headerHeight' => '375',
'map' => array(
'address' => $adresse,
'latitude' => $lat,
'longitude' => $lng,
'streetview' => '0',
'swheading' => '90',
'swpitch' => '5',
'swzoom' => '14'
),
'telephone' => '0221',
'telephoneAdditional' => '0228',
'email' => 'meister#rocks---.de',
'showEmail' => '1',
'contactOwnerBtn' => '1',
'web' => 'https://musicheadquarter.de',
'webLinkLabel' => '',
'displayOpeningHours' => '1',
'openingHoursMonday' => '12-17',
'openingHoursTuesday' => '12-17',
'openingHoursWednesday' => '12-17',
'openingHoursThursday' => '12-17',
'openingHoursFriday' => '12-17',
'openingHoursSaturday' => '12-17',
'openingHoursSunday' => '12-17',
'openingHoursNote' => 'Zusatzinfos zu den Öffnungszeiten',
'displaySocialIcons' => '0',
'socialIconsOpenInNewWindow' => '1',
'socialIcons' => array(
'icon' => 'fa-facebook-square',
'link' => 'https://rocks---.de'
),
'displayGallery' => '0',
'gallery' => array(
'title' => 'Titel des Bildes',
'image' => 'https://rocks---.de/wp-content/uploads/slide3___beach-2179183_1920.jpg'
),
'displayFeatures' => '0',
'features' => '0'
);
/* $data = maybe_serialize( $data ); */
update_post_meta( $post_id, '_ait-item_item-data', $data );
HOw do I create the ARRAY for the Images, social icons and telephone numbers.
I unserialized the Field Data and it shows the ARRAY, great!
array (
'featuredItem' => '0',
'headerType' => 'image',
'headerImage' => 'https://rockspots.de/wp-content/uploads/2018/08/IMG_2051.jpg',
'headerImageAlign' => 'image-left',
'map' =>
array (
'address' => 'Goslar',
'latitude' => '51.9059531',
'longitude' => '10.428996299999994',
'streetview' => '0',
'swheading' => '90',
'swpitch' => '5',
'swzoom' => '1',
),
'telephone' => '0221',
'telephoneAdditional' =>
array (
0 =>
array (
'number' => '111111111111',
),
1 =>
array (
'number' => '2222222222222',
),
2 =>
array (
'number' => '3333333333333',
),
),
'email' => 'goslarEmail#email.de',
'showEmail' => '1',
'contactOwnerBtn' => '1',
'web' => 'https://musicheadquarter.de',
'webLinkLabel' => 'Label of the Link',
'displayOpeningHours' => '1',
'openingHoursMonday' => '12',
'openingHoursTuesday' => '12',
'openingHoursWednesday' => '12',
'openingHoursThursday' => '12',
'openingHoursFriday' => '12',
'openingHoursSaturday' => '12',
'openingHoursSunday' => '12',
'openingHoursNote' => 'Text zu den Öffnungsziten',
'displaySocialIcons' => '1',
'socialIconsOpenInNewWindow' => '1',
'socialIcons' =>
array (
0 =>
array (
'image' => '',
'icon' => 'fa-facebook-square',
'iconColor' => '#00FF00',
'link' => 'http://festivaldate.de',
),
1 =>
array (
'image' => '',
'icon' => 'fa-instagram',
'iconColor' => '#00FF00',
'link' => 'https://rockspots.de',
),
),
'displayGallery' => '1',
'gallery' =>
array (
0 =>
array (
'title' => 'Bild 1',
'image' => 'https://rockspots.de/wp-content/uploads/2019/01/IMG_8797.jpg',
),
1 =>
array (
'title' => 'Bild 2',
'image' => 'https://rockspots.de/wp-content/uploads/2019/01/IMG_8443.jpg',
),
2 =>
array (
'title' => 'Bild 3',
'image' => 'https://rockspots.de/wp-content/uploads/2018/08/IMG_8545.jpg',
),
),
'displayFeatures' => '1',
'features' =>
array (
0 =>
array (
'icon' => '',
'text' => 'Feature Titel 1',
'desc' => 'Feature Titel Beschreibung 1',
),
1 =>
array (
'icon' => '',
'text' => 'Feature Titel 2',
'desc' => 'Feature Titel Beschreibung 2',
),
),
)
Now I need to know, how to create this part of the array. The number of images for the gallery is not fixed.
'gallery' =>
array (
0 =>
array (
'title' => 'Bild 1',
'image' => 'https://rockspots.de/wp-content/uploads/2019/01/IMG_8797.jpg',
),
1 =>
array (
'title' => 'Bild 2',
'image' => 'https://rockspots.de/wp-content/uploads/2019/01/IMG_8443.jpg',
),
2 =>
array (
'title' => 'Bild 3',
'image' => 'https://rockspots.de/wp-content/uploads/2018/08/IMG_8545.jpg',
),
),
Thanks for some tips,
