PHP，逐行阅读，无法正常工作

Question

我有这个代码。它的想法是，我逐行读取一个大的（非常大的：300mb）JSON文件，并将JSON数据设置为SQL表。但是同一行的JSON数据被多次插入，并且在PHP脚本通过所有行之后，它才重新开始。

JSON文件中有200268个对象，分隔行

这是我的代码：

使用example.php：

    <?php
/**

 * Copyright Adam Wulf 2013
 */

include("config-sample.php");
include("include.classloader.php");

$classLoader->addToClasspath(ROOT);


$mysql = new MySQLConn(DATABASE_HOST, DATABASE_NAME, DATABASE_USER, DATABASE_PASS);

$db = new JSONtoMYSQL($mysql);


$handle = fopen("programoversigter.json", "r");
if ($handle) {
    while (($linne = fgets($handle)) !== false) {

        $db->save(json_decode($linne)->_source, "igen");
        print($iasd . " ");
        $iasd = $iasd++;
    }

    fclose($handle);
} else {
    echo "assscsad";
}
die();
?>

include.classloader.php：

<?php
/**

class ClassLoader{
    protected $classpath;

    public function __construct(){
        $this->classpath = array();
    }

    public function addToClasspath($dir){
        if(is_dir($dir)){
            $this->classpath[] = $dir;
        }else{
            throw new Exception("cannot find directory: $dir");
        }
    }

    public function load($classname){
        $ok = false;
        for($i=0;$i<count($this->classpath);$i++){
            $path = $this->classpath[$i];
/*          echo "load recur \"" . $path . "\";//<br>\n"; */
            $ok = $ok || $this->load_recursive($path, $classname);
        }
        return $ok;
    }
