将两个数组组合成结果数组中的键和值？ [重复]
问题描述：
This question already has an answer here:
I have two arrays, one with the keys and the other with the values:
key_array = ['key1','key2','key3']
values_array = ['val1','val2','val3']
How do I iterate through them (their size will vary) to obtain this:
array('key1' => 'val1',
'key2' => 'val2',
'key3' => 'val3')
</div>

key_array = ['key1'，'key2'，'key3'] values_array = ['val1'，'val2'，'val3' ] code> pre>如何迭代它们（它们的大小会有所不同）来获得： p>
array（ 'key1'=＆gt;'val1'， 'key2'=＆gt;'val2'， 'key3'=＆gt;'val3'） code> pre> div>
答
Use array_combine():
$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);
print_r($c);
?>
Array
(
[green] => avocado
[red] => apple
[yellow] => banana
)
