php - 内存限制已耗尽

Question

在运行将大数据导入mysql的PHP脚本时，遇到以下错误:

memory exhausted near ''$GPGGA','130735.000','60.15751','N','24.74303','E','1','05','1.6','8.7','M','35' at line 1

我之前在我的 PHP INI 文件中分配了 256M 的内存限制。到目前为止，这个内存对于我的脚本来说已经足够了，到目前为止我还没有遇到任何问题。我导入了大小为 1MB 和 2.84MB 的文件，同时将内存限制保持在 256MB。当我运行大约 1MB 的文本文件时出现此错误。

我假设错误所指的内存是 PHP 内存限制。是否还有其他内存限制需要设置？我希望得到一些解决这个问题的建议。非常感谢。

if (is_array($inFile)) {

foreach($inFile as $inFileName) {

    $newFilePath = $upload_directory."/".$inFileName;

    if($inFileName != "")

    $handle = fopen($newFilePath,"r");
    $numlines =1;

    $query = "INSERT INTO gga_raw_data(device_id, gga_date,  nmea, gga_time, latitude, north, longitude, east, fixed_quality, no_of_satelites, hdop, altitude, meters, height_of_geoid, metres, check_sum, test_case_id) values";
    while (($data = fgetcsv($handle)) !== FALSE)
    {
        $numlines++;

        $myDay=substr($data[1], 0,2);
        $myMonth=substr($data[1], 2,2);
        $myYear=substr($data[1], 4,2);

        $gga_date = convertToNiceDate($myDay, $myMonth, 2000+$myYear);

        $longitude = convertToDegrees($data[6]);
        $latitude  = convertToDegrees($data[4]);


        if (!isset($data[16])) {
            $data[16] = '';
        }

        $query .="('$data[0]','$gga_date','$data[2]','$data[3]','$latitude','$data[5]','$longitude','$data[7]','$data[8]','$data[9]','$data[10]','$data[11]','$data[12]','$data[13]','$data[14]', '$data[15]', '$data[16])',";


    }

    $query = substr($query, 0,-1);

我不想开始一个新问题，因为它仍在这个问题上。我已经解决了“内存耗尽”问题，但现在 mySQL 查询错误让我的生活变得非常痛苦，我需要帮助。

这是我从文本文件输入数据的示例:

1,070610,$GPGGA,080323.460,6013.45368,N,02445.28396,E,1,04,4.6,18.3,M,35.0,M,,*67
1,070610,$GPGGA,080327.000,6013.44424,N,02445.31214,E,1,05,1.9,30.8,M,35.0,M,,*66

这是 echo $query 的结果:

INSERT INTO gga_raw_data(device_id, gga_date, nmea, gga_time, latitude, north, longitude, east, fixed_quality, no_of_satelites, hdop, altitude, meters, height_of_geoid, metres,check_sum) values('1','2010,06,07','$GPGGA','080323.460','60.22423','N','24.75473','E','1','04','4.6','18.3','M','35.0','M','')('1','2010,06,07','$GPGGA','080327.000','60.22407','N','24.7552','E','1','05','1.9','30.8','M','35.0','M','')

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('1','2010,06,07','$GPGGA','080327.000','60.22407','N','24.7552','E','1','05','1' at line 1

我注意到，输入数据中的最后一个变量“*67”没有被查询解析​​。我不确定它是否未被识别，因为它以 * 开头。

一次插入一行还是批量插入，比如一次插入 50 行...

$gen_query=$query; // keep $query as the stub

while (($data = fgetcsv($handle)) !== FALSE)
{
    $numlines++;

    ...
    $gen_query .="('$data[0]','$gga_date','$data[2]','$data[3]','$latitude','$data[5]','$longitude','$data[7]','$data[8]','$data[9]','$data[10]','$data[11]','$data[12]','$data[13]','$data[14]', '$data[15]', '$data[16])',";
   if ($numlines % 50 == 0) {
      mysql_query(substr($gen_query,0,-1));
      $gen_query=$query;
   }
}
if ($gen_query!=$query) mysql_query(substr($gen_query,0,-1));
