主要用到了mysql_fetch_assoc函数
mysql_fetch_assoc语法如下:
?

array mysql_fetch_assoc (resource $Result_Set)
范例代码如下:
?

?php
$UserName = 'abc';
$Password = '1234';
$DbHandle = mysql_connect ('localhost', $UserName, $Password);
if (!$DbHandle) {
die 'No database connection could be established.';
}
$DBName = 'w3db;
if (!mysql_select_db ($DBName, $DbHandle)) {
die 'Database could not be selected.';
}
$Query = "SELECT ISBN, Title, Author FROM articles";
$articles = mysql_query ($Query, $DbHandle));
while ($Row = mysql_fetch_assoc ($articles)) {
echo "ISBN = $Row['ISBN']br /\n";
echo "Title = $Row['Title']br /\n";
echo "Author = $Row['Author']br /\n";
}
?
$str='{"data":[{"name":"111","img":"748.jpg","dz":"uang","sz":"22"},{"name":"222","img":"888.jpg","dz":"ngzhu","sz":"13"},{"name":"333","img":"999.jpg","dz":"ve","sz":"27"}]}';
$json=json_decode($str,true);
echo $json['data'][0]['name']."br /";
echo $json['data'][0]['img']."br /";
echo $json['data'][0]['dz']."br /";
echo $json['data'][0]['sz']."br /";
//或者
$json=json_decode($str);
echo $json-data[0]-name."br /";
echo $json-data[0]-img."br /";
echo $json-data[0]-dz."br /";
echo $json-data[0]-sz."br /";
数据库提到的数据一般是资源类型的,要逐一读出,添加到数组
while($row = mysql_fetch_assoc($res)){
$data[] = $row;
}
遍历数据表,把相应的数据放到数组中即可
例如:
?php
//定义一个数组,用于保存读取到的数据
$contents = array();
$query = mysql_query("select * from table");
//遍历数据表
while($array = mysql_fetch_array($query)){
$contents[] = $array;
}
print_r($contents);
//然后循环数组,或者通过键名使用数组
foreach($contents as $value){
print_r($value);
}
echo $contents[0]['字段名称'];
