提取第一个数组的子字符串以从PHP中获取第二个数组的匹配值

Question

Given as an example:

$store = {A, B, C, D, E}

$price = {2, 10, 1, 500, 20}

Store[0]'s value is 2, [1] is 10, and so on. I'd like to know how to do that. I tried using min() but to no avail (unless I missed something out). Here's what I've done so far:

$x;

for ($x = $price.Count - 1; $x >= 0; $x--)

{

//this is the part where I can't figure it out
//compare prices here
//get the lowest price
//x = theSubstringOfTheLowestPrice

}

echo $store[x];

Answer 1

1. Your PHP code is not valid: $price = {A} means you must have constant A and php arrays are enclosed with array() or [].

2. Use array_combine() to create key-value pairs (demo):

$store = ['A', 'B', 'C', 'D', 'E'];

$price = [2, 10, 1, 500, 20];

$range = array_combine($store, $price);

var_dump($range['D']); // 500
