POST获取的JSON数据 [{"Name":"PM","Value":"224"},{"Name":"WD","Value":"25"},{"Name":"SD","Value":"34"},]
如何截取 Name＝WD 的Value？
求代码。
最简单的，循环查找呗。
$json = '[{"Name":"PM","Value":"224"},{"Name":"WD","Value":"25"},{"Name":"SD","Value":"34"}]';$jsonArr = json_decode($json) ;foreach ($jsonArr as $value) { if($value->Name == 'WD'){ echo $value->Value."<br />"; }}
$s = '[{"Name":"PM","Value":"224"},{"Name":"WD","Value":"25"},{"Name":"SD","Value":"34"}]';$t = array_filter(json_decode($s), function($v) { return $v->Name == 'WD'; });echo current($t)->Value; //25
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
