504
|
|
|
|
|
|
|
Read a file into a string. An the entire file is read from a string, there is no |
505
|
|
|
|
|
|
|
line at a time IO. This is because files are typically small and the parsing |
506
|
|
|
|
|
|
|
done is not line oriented. Binmode is an optional parameter that indicates file |
507
|
|
|
|
|
|
|
type if it is not a plain text file. |

510
|
|
|
|
|
|
|
|
511
|
|
|
|
|
|
|
Set the modification date of a file. Date is either in seconds or |
512
|
|
|
|
|
|
|
is in ISO format. |

515
|
|
|
|

|
|
516
|
|

|
|
|
Remove dotted directories ('.' and '..') from filename path. |

519
|
|
|
|
|
|
|
|
520
|
|
|
|
|
|
|
Split an absolute filename into a directory and the filename it contains. If |
521
|
|
|
|
|
|
|
the input filename is a directory, the filename is the empty string. |
522

524
|
|
|
|
|
|
|
|
525
|
|
|
|
|
|
|
Convert a directory name to the index file it contains. The extension |
526
|
|
|
|
|
|
|
is used in the index name. If the directory name is a file name, |
527
|
|
|
|
|
|
|
return it unchnged. |
528
|
|
|
|

530
|
|
|
|
|
|
|
|
531
|
|
|
|
|
|
|
Return a list of filenames and directories in a directory, |
532
|
|
|
|
|
|
|
|
533
|
|
|
|
|
|

=item fio_write_page($filename, $str, $binmode); |
534
|
|
|
|
|
|
|
|
535
|
|
|
|
|
|
|
Write a file from a string. An the entire file is written from a string, there |
536
|
|
|
|
|
|
|
is no line at a time IO. This is because files are typically small. Binmode is |
537
|
|
|
|
|
|
|
an optional parameter that indicates file type if it is not a plain text file. |
