我需要从多个关联数组中重叠数据,并考虑以下因素:
- 如果存在匹配的键,则覆盖它
- 如果键存在但不匹配,则将新值附加到该元素
- 如果以上都不是,则创建一个元素来存储该值
以以下结构为例:
<?php
for ($i = 0; $i < 10; $i++) {
$table["table_$i"] = array(
"cell_0" => array(
'row' => 12,
'column' => 5
)
);
}
for ($i = 4; $i < 12; $i++) {
$table["table_$i"] = array(
"cell_0" => array(
'row' => 9,
'column' => 8
)
);
}
for ($i = 5; $i < 15; $i++) {
$table["table_$i"] = array(
"cell_1" => array(
'row' => 4,
'column' => 1
)
);
}
?>
所需的输出如下所示:
{"table_0":{"cell_0":{"row":12,"column":5}},"table_1":{"cell_0":{"row":12,"column":5}},"table_2":{"cell_0":{"row":12,"column":5}},"table_3":{"cell_0":{"row":12,"column":5}},"table_4":{"cell_0":{"row":9,"column":8}},"table_5":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_6":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_7":{"cell_1":{"row":4,"column":1}},"table_8":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_9":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_10":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_11":{"cell_0":{"row":9,"column":8},"cell_1":{"row":4,"column":1}},"table_12":{"cell_1":{"row":4,"column":1}},"table_13":{"cell_1":{"row":4,"column":1}},"table_14":{"cell_1":{"row":4,"column":1}}}
请注意所需的输出,cell_0 的值不会替换 cell_1 的值:array_merge()
在这种情况下,我无法获得所需的输出。
任何帮助将不胜感激 - 谢谢!
