The above is the TXT format file data content, the file name "V5813101.012"
The format is: the first line, the description of the data file, as follows
Ordinal parameter number long remark
1. File Number 5 bytes
2. Year 5 bytes less than 5 bytes, front space
3. Month 5 bytes
4. Length 5 bytes.
5. Width 5 bytes
6. Alternate field 15 bytes Pre-fills each byte with a "-" (minus sign).
7. The height of 5 bytes high low when the front space.
8. Identification 5 bytes filled with "4"
9. Subsequent reserved bytes are populated with a "-" (minus sign) so that the parameter row is the same length as the subsequent data record line.
V1.00 4 bytes
11. Carriage return newline 2 bytes

Start with the second line
The minute data record line starts at line 2nd of the file, each hour is a record line, the length of each row is equal, and the record length is 60x5+6. The sorting order is: 2-bit "date", 2-bit "hour", 60-minute *5+2-bit "carriage return".

1 months for a file, there's Wood there's a very simple way to read the data and then write to the database.
A perfect match.

Can only say that you are too cow!!
But there's one more question.
7th line Error
Parse error:syntax error, unexpected t_function in read.php on line 7
If the line is commented out, it is printed out.

It's line 6th.

you haven't used php5.3 yet?
You can write a callback function separately

array_walk ($h, ' foo ', Array (' _ ' = ') '); function foo (&am  
 p; $v, $k, $t) {$v = Strtr ($v, $t);} 


The purpose of this callback is to change the space previously changed to "_" back to

Yes, it should be the version problem, thanks!
