从数组中删除索引[重复]

Question

我有以下数组：

array(3) { 
    [0]=> array(1) { ["theme_loader_plugin"]=> string(4) "_run" } 
    [1]=> array(1) { ["user_plugin"]=> string(4) "_run" } 
    [2]=> array(1) { ["sessions_plugin"]=> string(4) "_run" } 
} 

有没有办法使用预定义的 php 函数删除索引，而是像这样格式化它：

array(3) { 
    ["theme_loader_plugin"]=> string(4) "_run",
    ["user_plugin"]=> string(4) "_run",
    ["sessions_plugin"]=> string(4) "_run"
} 

Answer 1

遍历数组并将它们合并到新数组。希望它会有所帮助-

$arr = array( 
   array("theme_loader_plugin"=>  "_run" ) ,
   array("user_plugin"=> "_run" ) ,
   array("sessions_plugin"=> "_run" )
) ;

$new=  array();
foreach($arr as $val) {
  $new = array_merge($new, $val);
}

输出

array(3) {
  ["theme_loader_plugin"]=>
  string(4) "_run"
  ["user_plugin"]=>
  string(4) "_run"
  ["sessions_plugin"]=>
  string(4) "_run"
}
