Question

我有一个php脚本从sql数据库获取数据然后将其添加到数组并在json中对其进行编码然后打印它，但我想在将其添加到数组之前编辑其中一个项目，我该怎么做在将$row['name']添加到数组之前进行编辑？

很抱歉，这真的令人困惑！

$con = mysql_connect("localhost","username","password");
mysql_select_db("database", $con);

        $result = mysql_query("SELECT name,email,phone FROM table;");       
        $rows = array();
        while($row = mysql_fetch_array($result))
        {           
            $rows[] = $row;
         }
        $jTableResult = array();
        $jTableResult['aaData'] = $rows;
        print json_encode($jTableResult);

Answer 1

你可以这样添加：

while($row = mysql_fetch_array($result))
{
if($row['name'])
{
// do here what you want.
}  
$rows[] = $row;
}

Answer 2

while($row = mysql_fetch_array($result))
{ 
    $row['name'] = YourFunction($row['name']); //change it however you want
    $rows[] = $row;
}

Answer 3

根据您要修改$row['name']的方式，您可能会发现MySQL的String functions很有用。

我假设您要在查询中进行此修改。

// Add a string to the end of name
$result = mysql_query("SELECT CONCAT(name, 'string') name, email, phone FROM table");

// Or try replacing a part of the string
$result = mysql_query("SELECT REPLACE(name, 'old', 'new') name, email, phone FROM table");

$rows = array();
while ($row = mysql_fetch_array($result)) {           
  $rows[] = $row;
}
