php arrays string

在php中将字符串组合成数组,php,arrays,string,Php,Arrays,String,我有一个web服务，可以从外部数据库中识别人员及其功能，如果登录成功，该数据库将返回一组数据。数据（我现在感兴趣）以不同的字符串分隔，如下所示： $groups="group1, group2, group3" $functions="member, member, admin" 字符串$groups的第一个元素对应于$functions字符串的第一个元素 字符串中可以有空点： $groups="group1,, group3"; $functions="member,, admin"; 将

我有一个web服务，可以从外部数据库中识别人员及其功能，如果登录成功，该数据库将返回一组数据。数据（我现在感兴趣）以不同的字符串分隔，如下所示：

$groups="group1, group2, group3"
$functions="member, member, admin"
字符串
$groups
的第一个元素对应于
$functions
字符串的第一个元素

字符串中可以有空点：

$groups="group1,, group3";
$functions="member,, admin";
将它们结合在一起的最佳方式是什么：

$usertype(
    group1=>member, 
    group2=>member, 
    group3=>admin,
);
然后我计划使用
array\u search（）
获取与函数对应的组的名称

您是否尝试了
（$delimiter，$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);

$groups=“group1，group3”；
$functions=“member，，admin”；
$groups_array=数组_map（'trim'，explode（'，'，$groups））；
$functions_array=数组_map（'trim'，explode（'，'，$functions））；
$final=array（）；
对于（$i=0；$i您是否尝试了
（$delimiter，$string）
，然后过滤数组？我认为这是一种很好的方法：


$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);



$groups=“group1，group3”；
$functions=“member，，admin”；
$groups_array=数组_map（'trim'，explode（'，'，$groups））；
$functions_array=数组_map（'trim'，explode（'，'，$functions））；
$final=array（）；

对于（$i=0；$i来说，类似这样的东西应该有帮助：


$usertype = array_combine(explode(',', $groups), explode(',', $functions));



这样做应该会有所帮助：


$usertype = array_combine(explode(',', $groups), explode(',', $functions));


用于生成字符串数组，并将一个数组用作键，另一个数组用作值


$groups = "group1, group2, group3";
$functions = "member, member, admin";

$usertype = array_combine(explode(", ", $groups), explode(", ", $functions));


用于生成字符串数组，并将一个数组用作键，另一个数组用作值


$groups = "group1, group2, group3";
$functions = "member, member, admin";

$usertype = array_combine(explode(", ", $groups), explode(", ", $functions));


分解并组合数组。
请注意，您的空格有问题。因此请使用以下选项：


<?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));
?>


编辑：删除第一个元素可能为空的修剪。
分解并组合数组。

$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);

编辑：删除第一个元素为空的可能性的修剪。
这是一个非常巧妙的方法，尤其是当第一个元素为空时，但这里有一个全面的解决方案


$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);


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);



// 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);



// 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);
