[英]php foreach multidimensional associative array
我有如下的多維關聯數組
sr_array=>
array (size=18)
0 => string 'Shop' (length=4)
1 => string 'Papu Kushwaha' (length=13)
2 => string 'Jitendra Shukla' (length=15)
3 => string 'Satish' (length=6)
4 => string 'Pradeep' (length=7)
5 => string 'Papu Khan' (length=9)
6 => string 'Bharat' (length=6)
7 => string 'Manoj Pandey' (length=12)
8 => string 'select' (length=6)
'Shop' =>
array (size=9)
'count_auto' => int 60
'count_indus' => int 4
'count_mc' => int 100
'count_inverter' => int 10
'count_in_bat' => int 40
'total_credit' => int 191850
'sale_value' => int 1351755
'total_disc' => float 22377.38
'perc_disc' => float 1.66
等等....
現在我想以表格格式打印它們,我已經使用以下代碼進行輸出
echo"<table border=1>";
echo"<tr>";
echo"<th></th>";
for($i=0; $i < count($sr_array)/2; $i++){
$current_sr = $sr_array[$i];
echo"<th>{$current_sr}</th>";
}
echo"</tr>";
$keys = array_keys($sr_array);
for($i=0; $i < count($sr_array)/2; $i++){
$current_sr = $sr_array[$i];
echo"<tr>";
echo"<td></td>";
foreach($sr_array as $key => $var){
foreach($var as $x => $y)
echo"<td>{$y["count_auto"]}</td>";
}
echo"</tr>";
}
請幫我出去
-------------------------------------
| |Shop |xyz |abc |
-------------------------------------
count_auto |60 |75 | 85 |
-------------------------------------
count_indus | 25 | 74 |15 |
--------------------------------------
count_mc | 55 | 212 | 15 |

等等
我收到錯誤為foreach()提供的無效參數
提前致謝
這里的根本問題是,當您遍歷sr_array時,您假設這些值也是數組。 索引0到8並非如此(據我所知)。 這將解釋當前的問題。
理想情況下,數組的結構是一致的(理想情況下,是一個二維的行數組,每個行包含一組字段),然后一個簡單的嵌套循環就可以了。
結合使用for()
/ foreach()
和循環迭代,嘗試以下解決方案。
另外,將轉置的html表視為數據,將數據作為列,將描述性數據作為行。 否則,由於數組項未與html標記對齊,因此需要進行復雜的迭代。
echo "\n<table>\n";
$i = 0;
echo "\n<tr>\n";
echo "\n<th></th>\n";
foreach($sr_array as $item) {
echo "<th>". array_keys($item)[$i] ."</th>\n";
$i++;
}
echo "</tr>\n";
$j=0;
foreach($sr_array as $item) {
echo "\n<tr>\n";
echo "<td>" . array_keys($sr_array)[$j] . "</td>\n";
foreach($item as $key => $value)
{
echo "<td>". $value . "</td>\n";
}
echo "</tr>\n";
$j++;
}
echo "\n</table>\n";
並輸出如下(例如,我重復您發布的數據):
count_auto count_indus count_mc count_inverter count_in_bat total_credit sale_value total_disc perc_disc
