While running a PHP script that imports large data into mysql, I encountered the following error:
memory exhausted near ''$GPGGA','130735.000','60.15751','N','24.74303','E','1','05','1.6','8.7','M','35' at line 1
I have before now, assigned a memory limit of 256M in my PHP INI file. This memory has so far been sufficient for my sripts and I have experienced no issues till now. I have imported files of size 1MB and 2.84MB while keeping the memory limit at 256MB. THis error occured when I runned a text file of about 1MB.
I have assumed the memory the error is refering to is the PHP memory limit. Could there be any other memory limits to be set? I would appreciate some suggestions in resolving this problem. Many thanks.

I do not wish to start a new question since it is still on this issue. I have resovled the " memory exhaustion" issue but now have a a mySQL query error has made my life quite miserable and I need help.
This is a sample of my input data from a text file:
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
This is the result from echo $query:
INSERT INTO gga_raw_data(device_id, gga_date, nmea, gga_time, latitude, north, longitude, east, fixed_quality, no_of_satelites, hdop, altitude, meters, height_of_geoid, metres,check_sum) values('1','2010,06,07','$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
I have come to notice that, the last variable "*67" from the input data is not being parsed by the query. I am not sure if it is not being recognised since it begins with *.
