简单，只需将 JSON 对象转换为数组，然后遍历以构造 INSERT 查询：
SQL：
CREATE TABLE `gallery` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`lowsrc` varchar(255) DEFAULT NULL,
`fullsrc` varchar(255) DEFAULT NULL,
`description` text,
`category` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
PHP：
<?php
$json = '
[{
"lowsrc": "thumbnails\/1.jpg",
"fullsrc": "full\/1.jpg",
"description": "Zweifellos Mondbetont",
"category": "photography"
}, {
"lowsrc": "thumbnails\/2.jpg",
"fullsrc": "full\/2.jpg",
"description": "Mehmet Dere",
"category": "drawing"
}, {
"lowsrc": "thumbnails\/3.jpg",
"fullsrc": "full\/3.jpg",
"description": "Samantha Keely Smith",
"category": "drawing"
}, {
"lowsrc": "thumbnails\/4.jpg",
"fullsrc": "full\/4.jpg",
"description": "Kumi Yamashita. Created with thread and nails.",
"category": "handmade"
}, {
"lowsrc": "thumbnails\/5.jpg",
"fullsrc": "full\/5.jpg",
"description": "Alexander Semenov. Underwater macro photography.",
"category": "photography"
}, {
"lowsrc": "thumbnails\/6.jpg",
"fullsrc": "full\/6.jpg",
"description": "Borondo. Street Art.",
"category": "street art"
}, {
"lowsrc": "thumbnails\/7.jpg",
"fullsrc": "full\/7.jpg",
"description": "Anka Zhuravleva",
"category": "photography"
}, {
"lowsrc": "thumbnails\/8.jpg",
"fullsrc": "full\/8.jpg",
"description": "Guy Denning. Sketches.",
"category": "drawing"
}]';
$data = json_decode($json,true);
$link = mysqli_connect('dbhost', 'user', 'password', 'dbname') or die(mysqli_error($link));
foreach($data as $key=>$arr){
$fields = array();
$values = array();
foreach($arr as $k=>$v){
$fields[] = $k;
$values[] = mysqli_real_escape_string($link, $v);
}
$query = "INSERT INTO gallery (".implode(', ',$fields).") VALUES ('".implode("', '",$values)."')";
mysqli_query($link, $query) or die(mysqli_error($link));
}
?>
SQL 生成的输出：

INSERT INTO gallery (lowsrc, fullsrc, description, category) VALUES ('thumbnails/2.jpg', 'full/2.jpg', 'Mehmet Dere', 'drawing');
