这是:question的问题 按照Shrapnel上校的建议发布一个内容清晰的新问题。
我有一个Facebook用户喜欢的数据,即
{ "data": [ { "name": "Joker", "category": "Public figure" }, { "name": "Rafael Nadal", "category": "Athlete" }, { "name": "Lassi", "category": "Company" }, { "name": "Jacinda Barrett", "category": "Public figure" }, { "name": "cocacola", "category": "Company" }, { "name": "SWEENEY TODD", "category": "Movie" }, { "name": "The Notebook", "category": "Movie" }, { "name": "Unforgiven", "category": "Movie" } ]}
我想计算每个类别的数量(例如,这里是Movie = 3,company = 2等)并将其保存在mysql表中,我也想保存 其他表中每个类别的名称(即类别电影应该有电影(id,name)表,所有类别都相同)。什么 我做的是
$movie=0; // also define all variables here(i.e $company, $public figure etc) so that it would be increamented.
foreach($like['data'] as $jsondata=>$json)
{
if($json['category']==='Movie')
{
$name_movie=$json['name'];
$query1="insert into movies(id,name)values('', '" . mysql_real_escape_string($name_movie). "')";
$result1=mysql_query($query1) or die("error in query".mysql_error());
$movie++; // in the last this $movie++ will be inserted in other table
}
else
if($json['category']==='company')
{ do the same steps as above}
else
.
.
.
//similarly for all others categories
但是,就速度和一致性问题而言似乎效率低下
我的问题是我使用了正确的方法,还是应该有其他内容。
答案 0 :(得分:1)
这是代码的更简洁版本。我重新安排了json数据以创建按类别排序的数组:
$tables = array('movie', 'company'); //etc
$categories = array();
foreach($like['data'] as $jsondata=>$json)
{
$categories[$json['category']][] = $json['category'];
{
foreach($categories as $key => $category)
{
if (in_array($key, $tables))
{
$i = 0;
foreach($category as $item)
{
$query1="insert into " . $key . "(id,name)values('', '" . mysql_real_escape_string($item['name']). "')";
$result1=mysql_query($query1) or die("error in query".mysql_error());
$i++;
}
$category_count[$key] = $i;
}
}
