Out of memory

[sandy1028]

The code is reads the two files and sores into an array.
From the first file, 4th field and .xml is removed and is compared with the second file.
If the line exists in the second file, the line with 4th field and xml should be printed.

This works when the array size is small.
Suppose there are 230K above elements in the two files, it gives out of memory error.



How can I optimise the code, read the two files, and printin the lines, if it exists in first file


file1 contains

2000/03/01/aaa/aaa.xml
2003/05/11/ccc/bbb.xml
2008/08/05/bbb/ccc.xml

file 2 contains

2000/03/01/aaa

<?php

 $input_path = $argv[1];

        $content_inputfile = file($input_path);
        foreach ($content_inputfile as $content_input)
        {
                $content_input=rtrim($content_input);
                $data= explode("/",$content_input);
                $data[4] = preg_replace('/\.xml/','',$data[4]);
                $finalarr_delimited[] ="$content_input#$data[0]/$data[1]/$data[2]/$data[4]";
                $finalarr[] ="$data[0]/$data[1]/$data[2]/$data[4]";
        }

$dbfile_path = $argv[2];
        $content_dbfile = file($dbfile_path);
foreach ($content_dbfile as $content_db)
{
$str=strlen($content_db);
$content_db=rtrim($content_db);
$content_dbfil[]=$content_db;
sort($content_dbfil);
}

$differnece = array_diff($finalarr,$content_dbfil);

foreach ($finalarr_delimited as $line){
$position = strpos($line,"#")+1;
$lines = substr($line,$position);
if(in_array($lines,$differnece)){
$diff[]=$line;
}
}

echo "Checking the string in diff array\n";
foreach ($diff as $final){
$lines = explode("#",$final);
print "$lines[0]\n";
}

You are better of using mysql for handling such large amounts of data.
