H][RO Paranoid (IV) Inmate From: Australia Insane since: Oct 2002	posted 09-06-2006 04:01 Currently i am checking the used diskspace on my shared hosting accounts by using a php script which uses php functions such as ftp_rawlist, and then performing regular expressions on each line (file/directory) to extract the diskspace information. Now i think probably mostly due to the regular expression checking so many files, this process is very slow. Anyone know if there is a faster way to do this? The code is something like this: code: $rawList = ftp_rawlist ($this->objFtpconn, '-alR '.$dir); $Totalsize = 0; $TotalsizeOnDisk = 0; $blockSize = 512; $str = ''; foreach ($rawList as $file) { if( $file == '' ) continue; if(ereg("([-dl][rwxstST-]+).* ?([0-9 ]* )?([a-zA-Z0-9]+).* ([a-zA-Z0-9]+).* ([0-9]) ([a-zA-Z]+[0-9: ][0-9])[ ]+(([0-9]{2}:[0-9]{2})\|[0-9]{4}) (.+)", $file, $regs)) { $paramString = $regs[0]; $attributes = $regs[1]; $number = $regs[2]; // file or directory number $owner = $regs[3]; $group = $regs[4]; $size = $regs[5]; $date = $regs[6]; $time = $regs[7]; $name = $regs[8]; $sizeOnDisk = ceil($size/$blockSize) * $blockSize; $Totalsize += $size; // add the size even if its a dir $TotalsizeOnDisk += $sizeOnDisk; $str .= 'Name: '.$name .' Size: '.$size.' ('.$sizeOnDisk.') <br />'; } else { $str .= ' --------------------------------------------- '; $str .= $file. '(Not Counted!)<br />'; } }

The code is something like this:

code:

$rawList = ftp_rawlist ($this->objFtpconn, '-alR '.$dir);
        
        $Totalsize = 0;           
        $TotalsizeOnDisk = 0;
        $blockSize = 512;
        $str = '';

        foreach ($rawList as $file)
        {
            if( $file == '' ) continue;

            if(ereg("([-dl][rwxstST-]+).* ?([0-9 ]* )?([a-zA-Z0-9]+).* ([a-zA-Z0-9]+).* ([0-9]*) ([a-zA-Z]+[0-9: ]*[0-9])[ ]+(([0-9]{2}:[0-9]{2})|[0-9]{4}) (.+)", $file, $regs)) 
            {
             	$paramString = $regs[0];
             	$attributes = $regs[1];
             	$number = $regs[2]; // file or directory number
             	$owner = $regs[3];
             	$group = $regs[4];
             	$size = $regs[5];
             	$date = $regs[6];
             	$time = $regs[7];
             	$name = $regs[8];
             	
             	$sizeOnDisk = ceil($size/$blockSize) * $blockSize;
              	$Totalsize += $size; // add the size even if its a dir
              	$TotalsizeOnDisk += $sizeOnDisk;
              	$str .=  'Name: '.$name .' Size: '.$size.' ('.$sizeOnDisk.') <br />';
            }
            else
            {
            	$str .= ' --------------------------------------------- ';
            	$str .= $file. '(Not Counted!)<br />';
            }                                        
        }
