Counting strings in a txt file

[fathom274]

Hi I have a text file that I want to parse and count the strings.
The txt file looks like this;
087654321:987654321:987654321:987654321:1232456789 ........ up to 10M

I am able to read the text file and explode the results;

Code: Select all

$txt_file = file_get_contents('./10M.txt');
$pieces = explode(":", $txt_file);
$passed =1;
$failed= 0;


I would like to assign either 'PASSED' or 'FAILED' to each $pieces and then count the number of passes and fails.

Code: Select all

foreach($pieces as $row)
{
    if ($row == 987654321){
$count = $passed;
}
    else {
$count = $failed;
}
}


I have tried several ideas and methods using count, str_len, str_count etc.. but I can never seem to get the correct count.

Any Ideas?

what about...

Code: Select all

    $txt_file = file_get_contents('./10M.txt');
    $pieces = explode(":", $txt_file);
    $pieces = array_map(checkit,$pieces);
   $passed = array_sum($pieces);
   $failed = count($pieces)-$passed;
   

   function checkit($value)
   {
      return ($value==987654321)?1:0;
   }

100 ways to skin this cat

Code: Select all

<?php

$passed = 0;
$failed = 0;

$file = get_file_contents('myFile.txt');
$lines = explode(':',$file);
foreach($lines as $line) {
 (($line == '987654321') ? $passed += 1 : $failed += 1);
}

echo "\r\n
Passed: $passed \r\n
Failed: $failed \r\n
";

Much thanks, I was rather perplexed why my choices weren't working, I assumed there was a '100 way to skin this cat', but I guess my approach was faulty.

Solution 1: Can't get it to work
Solution 2: Count to 44445 MAX (have 10 000 000 results to parse)
Will work on it some more and see if I can tweak it.

PS: Running in Client not Browser

Thanks to you both

Count should read

Passed : 9999998
Failed: 2

But; I get a count;

Passed : 1111110
Failed : 2

Code: Select all

<?php

$passed = 0;
$failed = 0;
$letscount = 0;


$file = get_file_contents('myFile.txt');
$lines = explode(':',$file);

$total_count = count($lines);

foreach($lines as $line) {
 $letscount++;
 (($line == '987654321') ? $passed += 1 : $failed += 1);
}

echo "\r\n
Passed: $passed \r\n
Failed: $failed \r\n
Counted: $letscount \r\n
Total Lines: $total_lines\r\n 
";

I solved it, there are 10M numbers but only 1111110 complete string and one broken string and one disimilar string,

So effectively the count was right.

The results concur with the initial calculation and expected results.

I've re-run the original program out to 90M, but Unix kills the process past that, so I escaped it into 190M files at 90M each to give me results out to 1.71×10¹⁶ and the results always return 1 failed (the first which is 087654321) 1.9×10¹⁵ Passed and one incomplete.

Much thanks,

can you attach the file? i kind of want to test mine and see why it didn't work
