[PHP] searching for files in a directory with a specific structure.
Hi, I have a directory which has thousands of files based on date. for example mmdd-number(auto increment).txt 20050101-0001.txt,20050101-0002.txt20050101-0210.txt 20050102-0001.txt,20050102-0002.txt..20050102-0141.txt and many other files, but i want to extract data from the files with the above format. I have seen in the php documentation for reading a directory,but not files with a specific structure.i could not able to write the correct regular expression for the filename match. can some one give an idea. thanks babu. - Yahoo!

Check out http://php.net/glob. This might not be the best way to do it if you have *lots* of files since it returns all matches in an array. A regex to match might look something like \d\d\d\d\d\d\-\d\d\d\d\.txt but I'm no regex expert. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] searching for files in a directory with a specific structure.
thanks the format works,
i have written some code for deleting some lines from the above obtained
files,i have used like keyword match for deleting lines from the above
files.the keywords are in the array.
can u pls look at the code and check where goes wrong.
?
$del_lines=array([,TYP,P_MPP,I_MPP,V_MPP,T=,FIT,INTENSITAET);
$dir=getcwd();
$handle = opendir($dir);
while (false !== ($file = readdir($handle))) {
if ((preg_match('/^2005\d{4}_\d{4}\.txt$/',
$file))||(preg_match('/^2005\d{4}_\d{4}\_01_01\.txt$/',$file))){
$fc=file($file); // for reading
$f=fopen($file,w); // for writing.
foreach($fc as $line){
for($i=0;$isizeof($del_lines);$i++){
if(!strstr($line,$del_lines[$i]))
fputs($f,$line);
}
}
fclose($f);
}
}
closedir($handle);
