Php deletes a specific array value

Var_dump ($ context ['linktree']);

The

Array (3 ){
[0] =>
Array (2 ){
["Url"] =>
String (52) "http: // 127.0.0.1/testforum.cityofsteam.com/index.php"
["Name"] =>
String (28) "City of Steam Official Forum"
}
[1] =>
Array (2 ){
["Url"] =>
String (55) "http: // 127.0.0.1/testforum.cityofsteam.com/index.php?c1 ″
["Name"] =>
String (28) "City of Steam Official Forum"
}
[2] =>
Array (2 ){
["Url"] =>
String (62) "http: // 127.0.0.1/testforum.cityofsteam.com/index.php? Board = 4.0 ″
["Name"] =>
String (12) "Announcement"
}
}

I want to remove the middle one.

Use: unset ($ context ['linktree'] ['1']);

Array (2 ){
[0] =>
Array (2 ){
["Url"] =>
String (52) "http: // 127.0.0.1/testforum.cityofsteam.com/index.php"
["Name"] =>
String (28) "City of Steam Official Forum"
}
[2] =>
Array (2 ){
["Url"] =>
String (62) "http: // 127.0.0.1/testforum.cityofsteam.com/index.php? Board = 4.0 ″
["Name"] =>
String (12) "Announcement"
}
}

One [1] is missing.

Let the Middle 1 be automatically numbered:

Array ([0] => apple [1] => banana [3] => dog)

Function array_remove (& $ arr, $ offset)

{

Array_splice ($ arr, $ offset, 1 );

}

$ Arr = array ('apple', 'Banana ', 'cat', 'Dog ');

Array_remove ($ arr, 2 );

Print_r ($ arr );

?>

After testing, we can know that the element 2 is actually deleted and the index is re-created.
