我有一个Web服务,用于从外部数据库中识别人员及其功能,如果登录成功,则会返回一组数据。数据(我现在感兴趣的)用不同的字符串分隔如下:
$groups="group1, group2, group3"
$functions="member, member, admin"
字符串$groups
的第一个元素对应$functions
字符串的第一个元素。
我们可以在字符串中留空:
$groups="group1,, group3";
$functions="member,, admin";
将它们组合起来获得最佳方法是什么:
$usertype(
group1=>member,
group2=>member,
group3=>admin,
);
然后我计划使用array_search()
来获取与函数对应的组的名称。

这是非常有用的,特别是当第一个元素为空时,这里是一个全面的解决方案
您需要的是:
// Your Varriables
$groups = "group1,, group3";
$functions = "member,, admin";
// Break Into Array
$groups = explode(",", $groups);
$functions = explode(",", $functions);
// Combine both new Arrays and Output Result
$new = array_combine($groups, $functions);
print_r($new);
如果您需要修复null
值:
示例:
// Your Varriables
$groups = "group1,, group3";
$functions = "member,, admin";
// Break Into Array
$groups = explode(",", $groups);
$functions = explode(",", $functions);
// Fix Null Values
$groups = fixNull($groups, true);
$functions = fixNull($functions);
// Combine both new Arrays and Output Result
$new = array_combine($groups, $functions);
print_r($new);
输出
Array
(
[group1] => member
[group2] => member
[group3] => admin
)
更复杂:
// Your Varriables
$groups = ",,, group3";
$functions = ",member,, admin";
// Fix Null Values
$groups = fixNull(explode(",", $groups), true);
$functions = fixNull(explode(",", $functions));
// Combine both new Arrays and Output Result
$new = array_combine($groups, $functions);
print_r($new);
输出
Array
(
[group4] => member
[group5] => member
[group6] => member
[group3] => admin
)
使用的功能
function fixNull($array, $inc = false) {
$ci = new CachingIterator(new ArrayIterator($array), CachingIterator::FULL_CACHE);
if ($inc) {
$next = array_filter($array);
$next = current($next);
$next ++;
} else {
$next = array_filter($array);
sort($next);
$next = end($next);
}
$next || $next = null;
$modified = array();
foreach($ci as $item) {
$modified[] = empty($item) ? trim($next) : trim($item);
if (! $ci->getInnerIterator()->current()) {
$item || $item = $next;
$next = $inc ? ++ $item : $item;
}
}
return $modified;
}
答案 1 :(得分:1)
$groups = explode(",", $groups);
$functions = explode(",", $functions);
//then use the elements of the $groups array as key and the elements of the $functions array as the value
$merged = array_combine($groups, $functions);

有些事情应该有所帮助:
$usertype = array_combine(explode(',', $groups), explode(',', $functions));
答案 3 :(得分:1)
使用explode()
制作字符串数组,array_combine()
使用一个数组作为键,另一个数组作为值。
$groups = "group1, group2, group3";
$functions = "member, member, admin";
$usertype = array_combine(explode(", ", $groups), explode(", ", $functions));

您是否尝试过explode
($delimiter , $string)
然后过滤数组?我认为这是一个很好的方法:
$groups="group1,, group3";
$functions="member,, admin";
$groups_array = array_map('trim',explode(',', $groups));
$functions_array = array_map('trim',explode(',', $functions));
$final = array();
for ($i = 0; $i <= count($groups_array); $i++) {
$final[$groups_array[$i]] = $functions_array[$i];
}
$merged = array_combine($groups_array, $functions_array);
答案 5 :(得分:0)
explode和array_combine。 请注意,您有空格问题。因此请使用以下内容:
<?php
$groups="group1, group2, group3";
$functions="member, member, admin";
$groupArray = array_map(function($element){return trim($element);},
explode(',',$groups)); // split into array and remove leading and ending whitespaces
$functionArray = array_map(function($element){return trim($element);},
explode(',',$functions)); // split into array and remove leading and ending whitespaces
print_r(array_combine($groupArray,$functionArray));
?>
这将输出:
Array
(
[group1] => member
[group2] => member
[group3] => admin
)
编辑:删除了第一个元素为空的可能性。

$groups="group1, group2, group3"
$functions="member, member, admin"
preg_match_all('/\w+/', $groups, $groups);
preg_match_all('/\d+/', $functions, $functions);
$final = array();
foreach ($groups[0] AS $key => $letter)
$final[] = $letter . '=>' . $functions[0][$key];
echo join(', ', $final);
