The format of JSON data for PHP

PHP's Json_encode can convert an array into a JSON-formatted string. The string is not indented, and Chinese is converted to Unicode encoding, such as \U975A\U4ED4. It is more difficult to read by people. Now this method is json_encode on the basis of a further beautification process. Make it easy for people to read content.

1. Use Json_encode output

<?php  
      
Header (' Content-type:application/json;charset=utf8 ');  
      
$arr = Array (  
    ' status ' => true,  
    ' errmsg ' => ', ' member  
    ' =>array (  
        array (  
            ' name ' => ') Li Xiaoyao ',  
            ' gender ' => ' man '
        ),  
        Array (  
            ' name ' => ' Zhaoling ',  
            ' gender ' => '
        )  
") );  
      
echo Json_encode ($arr);  
      
? >

Output:

{' Status ': true, ' errmsg ': ' ', ' member ': [{' Name ': ' \u674e\u900d\u9065 ', ' Gender ': ' \u7537 '},{' name ': ' \u8d75\u7075\ u513f "," Gender ":" \u5973 "}]}

As you can see, this format is difficult for people to read.

2. Use Jsonformat output

<?php/** JSON Data format * @param Mixed $data data * @param String $indent indent characters, default 4 spaces * @return JSON * * FU Nction Jsonformat ($data, $indent =null) {//each element of the array UrlEncode operations recursively, protect Chinese characters//View more highlights in this column: Http://www.biance  
      
    Ng.cnhttp://www.bianceng.cn/webkf/php/array_walk_recursive ($data, ' jsonformatprotect ');  
      
    JSON encode $data = Json_encode ($data);  
      
    The contents of the UrlEncode are urldecode $data = UrlDecode ($data);  
    Indent processing $ret = ';  
    $pos = 0;  
    $length = strlen ($data); $indent = Isset ($indent)?  
    $indent: ';  
    $newline = "\ n";  
    $prevchar = ';  
      
    $outofquotes = true;  
      
        for ($i =0; $i <= $length; $i + +) {$char = substr ($data, $i, 1);  
        if ($char = = ' "' && $prevchar!= ' \") {$outofquotes =! $outofquotes;  
            }elseif ($char = = '} ' | | | $char = = '] && $outofquotes) {$ret. = $newline; $pos--;  
            for ($j =0; $j < $pos; $j + +) {$ret. = $indent;  
              
        }} $ret. = $char;  
            if ($char = = ', ' | | | $char = = ' {' | | = $char = = ' [') && $outofquotes) {$ret. = $newline;  
            if ($char = = ' {' | | | $char = = ' ['] {$pos + +;  
            for ($j =0; $j < $pos; $j + +) {$ret. = $indent;  
    }} $prevchar = $char;  
return $ret; /** the array element UrlEncode * @param String $val/function Jsonformatprotect (& $val) {if ($val!==true  
    ;& $val!==false && $val!==null) {$val = UrlEncode ($val);  
      
} header (' Content-type:application/json;charset=utf8 ');  
            $arr = Array (' status ' => true, ' errmsg ' => ', ' member ' =>array Array ( ' Name ' => ' Li Xiaoyao ', ' Gender ' => ' man '
        ), Array (' name ' => ' Zhaoling ', ' Gender ' => '));  
      
echo Jsonformat ($arr); ?>

Output:

{  
    "status": True, "  
    errmsg": "",  
    "member": [  
        {  
            "name": "Li Xiaoyao",  
            "gender": "Male"
        },  
        { "  
            name": "Zhaoling Child",  
            "gender": "Female"
        }  
    ]  
}
