PHP - Merge two arrays (same-length) into one associative?
提问by Ropstah
pretty straightforward question actually..
其实很简单的问题..
is it possible in PHP to combine two separate arrays of the same length to one associative array where the values of the first array are used as keys in the associative array?
是否可以在 PHP 中将两个长度相同的单独数组组合成一个关联数组，其中第一个数组的值用作关联数组中的键？
I could ofcourse do this, but I'm looking for another (built-in) function, or more efficient solution..?
我当然可以这样做，但我正在寻找另一个（内置）功能，或更有效的解决方案..？
function Combine($array1, $array2) {
if(count($array1) == count($array2)) {
$assArray = array();
for($i=0;$i<count($array1);$i++) {
$assArray[$array1[$i]] = $array2[$i];
}
return $assArray;
}
}

you need array_combine.
你需要array_combine。
<?php
$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);
print_r($c);
?>

There's already an array_combinefunction:
已经有一个array_combine功能：
$combined = array_combine($keys, $values);

hello everybody i will show you how to merge 2 arrays in one array
大家好，我将向您展示如何将 2 个数组合并为一个数组
we have 2 arrays and i will make one array from them
我们有 2 个数组，我将从它们中创建一个数组
$data_key = array('key1','key2');
$data_value = array('val1','val2');
lets declare the main array
让我们声明主数组
$main_array = array();
now let's fill it with the 2 arrays
现在让我们用 2 个数组填充它
foreach ($data_key as $i => $key) {
$main_array[$key] = $data_value[$i];
}
now let's see the result by using var_dump($main_array);
现在让我们看看结果 var_dump($main_array);
array(2) {
["key1"]=> string(4) "val1"
["key2"]=> string(4) "val2"
}
i hope that can help someone :)
我希望可以帮助某人:)
