PDO只插入最后一个绑定参数 - PDO inserting only last Bound parameter

PDO inserting only last Bound parameter

我编写了一个带有查询函数的pdo包装器类，可以在执行前自动获取数组并将值绑定到语句。

public function query($query, $sprints = NULL)
{
    // Add query to the last query and benchmark
    $bench['query'] = $query;
    // Prepare the statement
    $this->result = $this->pdo->prepare($query);
    // Process our sprints and bind parameters
    if(is_array($sprints))
    {
        // Bind our parameters
        foreach($sprints as $key => $value)
        {
            // if we are using "?'s", then we up the keys +1
            if(is_int($key)) ++$key;
            // Bid the param based on its type
            if(is_int($value))
            {
                // Bind the param
                $this->result->bindParam($key, $value, 'PDO::PARAM_INT);
                $bench['bound'][$key] = $value;
            }
            else
            {
                // Bind the param
                $this->result->bindParam($key, $value, 'PDO::PARAM_STR, strlen($value));
                $bench['bound'][$key] = $value;
            }
        }
    }
    // Time, and process our query
    $start = microtime(true);
    try {
        $this->result->execute();
    }
    catch ('PDOException $e) { 
        // show error
    }
    $end = microtime(true);
    // Get our benchmark time
    $bench['time'] = round($end - $start, 5);
    // Get our number of rows
    $this->num_rows = $this->result->rowCount();
    // Add the query to the list of queries
    $this->queries[] = $bench;
    // Return
    return $this;
}

问题是，在Insert操作中，它用最后一个绑定参数替换了所有的?下面是查询和结果:

INSERT INTO sessions(`token`,`ip_address`,`last_seen`,`user_data`) VALUES (?, ?, ?, ?)

绑定参数为:

[bound] => Array ( [1] => test1 [2] => 0.0.0.0 [3] => test3 [4] => test4 )

在数据库中的结果是，所有4列都被test4填充。有人知道它为什么这样做吗?

不知道你有什么问题，但为什么不把它改成

$this->result = $this->pdo->prepare($query); 
$this->result->execute($sprints);

使用bindValue，而不是bindParam

<?php
if ( count( $this->_params ) > 0 )
    {
        foreach ( $this->_params as &$param )
        {
            $statement->bindValue( ":{$param->name}", $param->value, $param->type );
        }
    }
