This is the PHP equivalent of javascript Function#apply(generate an argument list from an array):
这是 javascript 的 PHP 等价物Function#apply（从数组生成参数列表）：
$result = call_user_func_array("array_merge", $input);

This may work:
这可能有效：
$array1 = array("item1" => "orange", "item2" => "apple", "item3" => "grape");
$array2 = array("key1" => "peach", "key2" => "apple", "key3" => "plumb");
$array3 = array("val1" => "lemon");
$newArray = array_merge($array1, $array2, $array3);
foreach ($newArray as $key => $value) {
echo "$key - <strong>$value</strong> <br />";
}

array_merge can do the job
array_merge 可以完成这项工作
$array_meged = array_merge($a, $b);

If fixed indexs you can use:
如果固定索引，您可以使用：
$array_meged = array_merge($a[0], $a[1]);
A more generic solution:
更通用的解决方案：
$array_meged=array();
foreach($a as $child){
$array_meged += $child;
}

$arr1 = array(0=>1);
$arr2 = array(0=>2);
$merged = array_merge($arr1,$arr2);
print_r($merged);

$resultArray = array_merge ($array1, $array1);
$resultArray = array_merge ($array1, $array1);
$result = array();
foreach ($array1 as $subarray) {
$result = array_merge($result, $subarray);
}
// Here it is done

array_mergeis what you need.
array_merge是你所需要的。
$arr = array_merge($arr1, $arr2);
Edit:
编辑：
$arr = array_merge($arr1[0], $arr1[1]);
