JSON 文件怎么读取

[whl20080122]

json.txt 文件
{
"programmers": [
{ "firstName": "Brett", "lastName":"McLaughlin", "email": "[e-mail]" },
],
"authors": [
{ "firstName": "Isaac", "lastName": "Asimov", "genre": "science fiction" },
],
"musicians": [
{ "firstName": "Eric", "lastName": "Clapton", "instrument": "guitar" },
]
}


需要读取类别的名字！！

另外...你那个json文件格式有错,

    {
        "programmers": [{
            "firstName": "Brett",
            "lastName": "McLaughlin",
            "email": "[e-mail]"
        } ],
        "authors": [{
            "firstName": "Isaac",
            "lastName": "Asimov",
            "genre": "science fiction"
        } ],
        "musicians": [{
            "firstName": "Eric",
            "lastName": "Clapton",
            "instrument": "guitar"
        } ]
    }

json.txt 文件
{
"programmers": [
{ "firstName": "Brett", "lastName":"McLaughlin", "email": "[e-mail]" },
],
"authors": [
{ "firstName": "Isaac", "lastName": "Asimov", "genre": "science fiction" },
],
"musicians": [
{ "firstName": "Eric", "lastName": "Clapton", "instrument": "guitar" },
]
}

mixed json_decode ( string $json [, bool $assoc ] )

接受一个 JSON 格式的字符串并且把它转换为 PHP 变量
这是手册里写的。

使用json_decode函数

$filename = "json.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
var_dump($contents);
var_dump(json_decode($contents);
