在for循环PHP中获取列名和值 [英] Get column names and values in for loop PHP

问题描述

我想从特定表中获取所有列名和值.此表中的字段不是固定的，因此有时用户会添加一个字段，也可以删除它们.我想要做的是检索所有列名并获取它的值.就我现在而言，正在检索列名并从中获取一个值.我知道为什么我会得到这个结果，但我不知道如何解决它.

I would like to get all column names and values from a specific table. The fields in this table aren't fixed, so sometimes there will be added one field by the user and they also can be removed. What I want to do is retrieve all column names and getting the values of it. As far as I am now is retrieving the column names and getting one value out of it. I know why I get this result, but I don'tknow how to fix it.

//I edited this sql, normally the table value and id are variable
$sql = "SELECT * FROM ".$_POST['moduleName']." WHERE modItemID= ".$_POST['modItemID']; 
$query = mysql_query($sql); 
$columns = mysql_num_fields($query); 
for($i = 1; $i < $columns; $i++) { 

//read field name
  $fieldName = mysql_field_name($query,$i);
  while($row = mysql_fetch_assoc($query,$i)){
    echo $fieldName."=".$row[$fieldName];   
  }

}  

结果:naam=Ketting

result: naam=Ketting

推荐答案

实际上很容易解决你的问题是使用 foreach 循环，像这样:

Actually really easy solution to your problem would be to use foreach loop, like so:

while($row = mysql_fetch_assoc($query))
{
    foreach($row as $key => $value)
    {
        echo "$key=$value";
    }
}
