我有两个从
JSON转换的数据对象.两者都非常复杂,我想以类似的方式将它们合并到jQuery将如何使用extends合并两个对象.
例
JSON 1:
{ ... "blah": { "params": { "foo": { "default": "bar","misc": "0",... },... },... },... }
JSON 2:
{ ... "blah": { "params": { "foo": { "value": "val","misc": "1",... }
合并成
{ ... "blah": { "params": { "foo": { "default": "bar","value": "val",... }
将每个JSON字符串解码为关联数组,合并结果并进行重新编码
原文链接:https://www.f2er.com/php/140233.html$a1 = json_decode( $json1,true ); $a2 = json_decode( $json2,true ); $res = array_merge_recursive( $a1,$a2 ); $resJson = json_encode( $res );
更新:
如果您具有特定的合并要求,则需要编写自己的合并功能.
我在下面写了一个符合您的要求的问题.
如果您还没有提到其他要求,则可能需要进行调整.
<?PHP $json1 = ' { "blah": { "params": { "foo": { "default": "bar","misc": "0" } },"lost": { "one": "hat","two": "cat" } } }'; $json2 = ' { "blah": { "lost": "gone","params": { "foo": { "value": "val","misc": "1" } } },"num_array": [12,52,38] }'; $a1 = json_decode( $json1,true ); /* * Recursive function that merges two associative arrays * - Unlike array_merge_recursive,a differing value for a key * overwrites that key rather than creating an array with both values * - A scalar value will overwrite an array value */ function my_merge( $arr1,$arr2 ) { $keys = array_keys( $arr2 ); foreach( $keys as $key ) { if( isset( $arr1[$key] ) && is_array( $arr1[$key] ) && is_array( $arr2[$key] ) ) { $arr1[$key] = my_merge( $arr1[$key],$arr2[$key] ); } else { $arr1[$key] = $arr2[$key]; } } return $arr1; } $a3 = my_merge( $a1,$a2); $json3 = json_encode( $a3 ); echo( $json3 ); /* { "blah": { "params": { "foo": { "default": "bar","misc": "1","value": "val" } },"lost": "gone" },38] } */
