我有两个关联数组。 $dpt_total是部门列表，以及这些部门的总数。 $cl_subtotal是部门、类和小计的多维数组。
和总计，然后显示与该部门关联的类以及该类的小计。例如：
vdump($dpt_total);
array(2) {
'None' → float 132.88
'instore bakery' → float 786.24
}
Sizes: 2
vdump($cl_subtotal);
array(2) {
'None' → array(1) {
'None' → float 132.88
}
'instore bakery' → array(10) {
'pies' → float 70.94
'cakes' → float 146.71
'miscellaneous' → float 25.57
'cookies' → float 52.38
'brownies' → float 33.96
'rolls' → float 143.02
'danish' → float 90.42
'bagels & pretzels' → float 85.68
'breads' → float 55.73
'dessert case' → float 81.83
}
}
应显示这些：
Department Class Total
--------------------------------
None 132.88
None 132.88
Instore Bakery 786.24
pies 70.94
cakes 146.71
misc 25.57
cookies 52.38
(and so on)
一个简单的嵌套 foreach 语句应该可以得到你想要的：
foreach($cl_subtotal as $department=>$classes){
//formatting
//also note you can use $department as a key for $dpt_total ex:
//$dpt_total[$department] will give you the total for the department
foreach($classes as $class=>$price){
//formatting
}
}
希望这有所帮助。
$tbl=array();
foreach($dpt_total as $key=>$val){
$row=array($key,'',$val);
$tbl[]=$row;
$tmp=$cl_subtotal[$key];
foreach($tmp as $key2=>val2){
$row=array('',$key,$val);
$tbl[]=$row;
}
}
$table='<table><tr><th>Department</th><th>Class</th><th>Total</th></tr>'
foreach($tbl as $row){
$table.='<tr>';
foreach($row as $col){
$table.='<td>'.$col.'</td>';
}
$table.='/<tr>';
}
$table.='</table>';
