在嵌套数组中，我想用y改变键x。例如：如何在PHP中更新嵌套数组中的键？
clonedAssetSource - 1479722826:clonedAssetSource - 1479722826._jvxMatchCount
应该变成：
clonedAssetSource - 2000:clonedAssetSource - 2000._jvxMatchCount.
我写了一个递归解决方案，但它不工作。这里是我解码成一个嵌套的数组的JSON：
{
"defaultAssetGroup":"def",

{
"id":"R-136-11821-1479722207355",

这是我的代码片段：
function updateConditions(&$conditions, $oldDataServiceName, $newDataServiceName) {
foreach($conditions as $condIndex => $condition){
foreach($condition['selectors'] as $selIndex => $sel)
foreach($sel as $ruleIndex => $condValue){
if($ruleIndex != 'id' && $ruleIndex !='comparator') {
$compareKey = $oldDataServiceName.":".$oldDataServiceName."._jvxMatchCount";
if($ruleIndex == $compareKey) {
unset($conditions[$condIndex]['selectors'][$selIndex][$ruleIndex]);
$newKey = $newDataServiceName.":".$newDataServiceName."._jvxMatchCount";
$conditions[$condIndex]['selectors'][$selIndex][$newKey] = $condValue;
}
}
}
}
if(isset($condition['conditions'])){
updateConditions($condition['conditions'], $oldDataServiceName, $newDataServiceName);
}
}
return true;
}
，我叫上述功能如下传递数组$ rulePackageArr：
if(!empty($newDataServiceNames)) {
foreach ($newDataServiceNames as $oldDataServiceName => $newDataServiceName) {
if(!empty($rulePackageArr['data'])){
foreach($rulePackageArr['data'] as $key => $data){
updateConditions($rulePackageArr['data'][$key]['conditions'], $oldDataServiceName, $newDataServiceName);
}
}
}
}
为什么不使用正则表达式：您可以通过使
$condition变量的引用，与&词缀解决这个问题？ – Eric请注意，您在第二个'foreach'中缺少左括号。 – trincot
注意：我删除了'json'标签。数组从JSON解码出来的事实在这里并不重要。 – trincot
