PHP decoding Unicode encoding Chinese character code example

After crawling a Web site data, the results found a string of encoded data in the packet: ".... \u65b0\u6d6a\u5fae\u535a ...", this is actually Chinese Unicode encoded after the data, want to decode the Chinese.
Solution:
Scenario A (Stable + recommended):

functionReplace_unicode_escape_sequence ($match) {returnMb_convert_encoding (Pack(' h* ',$match[1]), ' UTF-8 ', ' ucs-2be ');}$name= ' \u65b0\u6d6a\u5fae\u535a ';$str=Preg_replace_callback('/\\\\u ([0-9a-f]{4})/I ', ' replace_unicode_escape_sequence ',$name);Echo $str;//output: Sina Weibo//www.jbxue.com Script Academy//We will package the above scenario A to wrap up ~ ~ ~ (Plan a stable version + upgrade + recommended)classhelper_tool{Static functionUnicodedecode ($data){ functionReplace_unicode_escape_sequence ($match) {returnMb_convert_encoding (Pack(' h* ',$match[1]), ' UTF-8 ', ' ucs-2be ');} $rs=Preg_replace_callback('/\\\\u ([0-9a-f]{4})/I ', ' replace_unicode_escape_sequence ',$data);return $rs;} }//called$name= ' \u65b0\u6d6a\u5fae\u535a ';$data= Helper_tool::unicodedecode ($name);//output Sina Weibo

Scenario B (Recommended):

<?PHPfunctionUnicodedecode ($name){$json= ' {' str ': '.$name.‘"}‘;$arr= Json_decode ($json,true);if(Empty($arr))return‘‘; return $arr[' Str '];} //www.jbxue.com$name= ' \u65b0\u6d6a\u5fae\u535a ';EchoUnicodedecode ($name);//output: Sina Weibo

For scenario B, note that in the friend XAR (Poke XAR blog) technical support, summed up the string to be processed (that is, the parameters passed to the function Unicodedecode $name must not contain single quotation marks, otherwise it will lead to parsing failure, so if necessary, you can use str The _replace () function formats illegal characters as qualified characters)
