现在的代码是这样的
array(6) {
[0] => string(5) "58,86"
[1] => string(5) "68,78"
[2] => string(5) "65,78"
[3] => string(5) "60,82"
但是数据处理需要得到的内容应该为
array(1){
一个支持多语言的，用php技术开发的开源FAQ(问答)系统，类似百度知道，支持多种数据库，phpMyFAQ具有内容管理功能，图片管理，支持多用户、用户组、新闻系统、用户跟踪、语言模块，支持Microsoft Active Directry活动目录。

<code>[0] => 58,68,65,60 [1] => 86,78,78,82</code>
}
请问下 数据处理 如何处理
想了想之后 思路是 先遍历然后 拆分值 再拼接 只不过在最后组装的时候有1个空的key 不知道从哪里来的
array(6) {
[0] => string(5) "58,86"
[1] => string(5) "68,78"
[2] => string(5) "65,78"
[3] => string(5) "60,82"
[4] => string(3) "094"
[5] => string(2) "40"
}、

foreach($lsj['data'] as $key=>$val){
<code> $a[''] = $a[$key] = explode(',',$val);
}
</code>之后得到
array(7) {
[0] => array(2) {
<code>[0] => string(2) "58" [1] => string(2) "86"</code>
}
[""] => array(1) {
<code>[0] => string(2) "40"</code>
}
[1] => array(2) {
<code>[0] => string(2) "68" [1] => string(2) "78"</code>
}
[2] => array(2) {
<code>[0] => string(2) "65" [1] => string(2) "78"</code>
}
[3] => array(2) {
<code>[0] => string(2) "60" [1] => string(2) "82"</code>
}
[4] => array(1) {
<code>[0] => string(3) "094"</code>
}
[5] => array(1) {
<code>[0] => string(2) "40"</code>
}
}
然后在把相同的key 组装成一个新的数组 因为本人的PHP版本为5.4无法使用array_column 所有写了一个公共的方法 i_array_column()
$b['data1'] = i_array_column($a,'0');
$b['data2'] = i_array_column($a,'1');
得到1个数组
array(2) {
["data1"] => array(7) {
<code>[0] => string(2) "58" [""] => string(2) "40" [1] => string(2) "68" [2] => string(2) "65" [3] => string(2) "60" [4] => string(3) "094" [5] => string(2) "40"</code>
}
["data2"] => array(7) {
<code>[0] => string(2) "86" [""] => NULL [1] => string(2) "78" [2] => string(2) "78" [3] => string(2) "82" [4] => NULL [5] => NULL</code>
}
}
因为highcharts需要json格式 所以转换json格式
dump(json_encode($b));、
准换后结果为
string(146) "{"data1":{"0":"58","":"40","1":"68","2":"65","3":"60","4":"094","5":"40"},"data2":{"0":"86","":null,"1":"78","2":"78","3":"82","4":null,"5":null}}"
只不过不知道为什么会有一个空的数组

只不过不知道为什么会有一个空的数组
<code class="php"><?php
$arr = ["58,86,1,18",
"68,78,2,17",
"65,78,3,17",
"60,82,4,19",
"4,5,6,18"];
array_walk($arr, function(&$item) {
$item = explode(',', $item);
});
$new_arr = [];
$length = count($arr);
for ($i = 0; $i < $length; $i++) {
$length1 = count($arr[$i]);
for ($j = 0; $j < $length1; $j++) {
$new_arr[$j][$i] = $arr[$i][$j];
}
}
array_walk($new_arr, function(&$item) {
$item = join(',', $item);
});
print_r($new_arr);</code>矩阵转置, 上面这个方法可以推广到多维矩阵
写一个仅为你这个情况作处理的，分析了一下，你这个情况是把数组内的字符串进行分割的处理
<code> $arr = array("58,86","68,78","65,78","60,82");
foreach($arr as $key => $value){
$tmp = explode(',',$value);
$a[] = $tmp[0];
$b[] = $tmp[1];
}
$c = array(
implode(',',$a),implode(',',$b)
);
print_r($c);</code>
