在运行将大数据导入 mysql 的 PHP 脚本时,我遇到了以下错误:
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,这个内存已经足够我的脚本了,到目前为止我还没有遇到任何问题。我已导入大小为 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 的文本文件时发生此错误。
我假设错误所指的内存是 PHP 内存限制。是否可以设置任何其他内存限制?我会很感激一些解决这个问题的建议。非常感谢。

我不想开始一个新问题,因为它仍然在这个问题上。我已经解决了“内存耗尽”问题,但现在有一个 mySQL 查询错误让我的生活非常痛苦,我需要帮助。
这是来自文本文件的输入数据示例:
1,070610,$GPGGA,080323.460,6013.45368,N,02445.28396,E,1,04,4.6,18.3,M,35.0,M,,*67

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。我不确定它是否不被识别,因为它以 * 开头。
