Php 在While循环中为每个迭代运行公共函数

我是PHP新手，已经做了一些关于如何编写页面代码以运行代码隐藏的教程。我很难弄清楚为什么我的While循环只在循环的第一次迭代中执行一个公共函数。有什么想法吗

while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$info = array("name" => "", "class" => "", "description" => "", "characteristics" => "");
        for  ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
            $info[$c] = $data[$c];
        }
        echo print_r($info);
        infoDB::getInstance()->create_record($info[0],$info[1],$info[2],$info[3]);}

问题解决

public function create_record ($info, $class, $description, $characteristics) {
$this->query("INSERT INTO tbl_info (toon, zeta, description, characteristics)" . " VALUES ('" . $toon . "', '" . $zeta . "', '" . $description . "', '" . $characteristics . "')");

}

现在是

public function create_record ($info, $class, $description, $characteristics) {
    $name = $this->real_escape_string($name);
    $class = $this->real_escape_string($class);
    $description = $this->real_escape_string($description);
    $characteristics = $this->real_escape_string($characteristics);
$this->query("INSERT INTO tbl_info (toon, zeta, description, characteristics)" . " VALUES ('" . $toon . "', '" . $zeta . "', '" . $description . "', '" . $characteristics . "')");

}

查询失败，因为它从源电子表格中读取的内容需要转义

您应该在for循环中调用函数以获得结果

$[$c]=$data[$c]这似乎很奇怪。您还将关联数组分配给
$info
（即使用命名键），但在调用
create\u record
时尝试使用索引键。也无法确定这是否是整个
while
循环。创建一个最小的示例-删除代码，直到只有
while
循环和一个
变量转储（$data）并从那里开始工作。编辑以澄清这是一个相当简单的循环，它显然在阵列正常打印时工作。最后一行是循环中唯一不随每次迭代一起运行的部分，循环的其余部分是上下文“最后一行是循环中唯一不随每次迭代一起运行的部分，”…可能查询由于某种原因失败。您是否已打开错误报告和/或日志记录？当查询失败时，数据库库是否抛出异常，或者是否需要手动检查（有时这是一个php配置问题）？
public function create_record ($info, $class, $description, $characteristics) {
    $name = $this->real_escape_string($name);
    $class = $this->real_escape_string($class);
    $description = $this->real_escape_string($description);
    $characteristics = $this->real_escape_string($characteristics);
$this->query("INSERT INTO tbl_info (toon, zeta, description, characteristics)" . " VALUES ('" . $toon . "', '" . $zeta . "', '" . $description . "', '" . $characteristics . "')");
