multi file / multi tasked php

[trauch]

So as to not confuse anyone regarding my progress I have started a new thread.

 

I'm working on a script that will perform a few tasks

1) Load multiple text files each of which contains a line of numbers

2) In each text file remove white space and then add all lines

3) Append the contents of all of these text files to another text file

4) Add all numbers in the resulting text file

5) Save that resulting number as a new text file whose name is generated as the current date. (ie 2008-12-22.txt)

 

I've got some messy code below but would appreciate any assistance.

 

<?php

$data1 = file('textfile1.txt');
$data1 = str_replace(' ','',$data1);
echo 'sum($data1) = ' . array_sum($data1) . "\n";
$sum = array_sum($data1) . "\n";

$data2 = file('textfile2.txt');
$data2 = str_replace(' ','',$data2);
echo 'sum($data2) = ' . array_sum($data2) . "\n";
$sum2 = array_sum($data2) . "\n";

$data3 = file('textfile3.txt');
$data3 = str_replace(' ','',$data3);
echo 'sum($data3) = ' . array_sum($data3) . "\n";
$sum3 = array_sum($data3) . "\n";


$fp = fopen('textmaster.txt', 'a');
fwrite($fp, $sum);
fwrite($fp, $sum2);
fwrite($fp, $sum3);

fclose($fp);

?>

There are a few ways of doing it, but this is how I would do it:

<?php
// Make an array of the filenames to sum
$fileNames = array('textfile1.txt', 'textfile2.txt', 'textfile3.txt');

// Open the file and zero out the net sum
$fp = fopen('textmaster.txt', 'a');
$netSum = 0;

// Add the numbers and append to the file
foreach($fileNames as &$fileName) {
$content = str_replace(' ', '', file($fileName)); // Perhaps use preg_replace to remove ALL whitespace instead of just spaces?
$sum = array_sum($content);
echo 'Sum of "' . $fileName . ': ' . $sum;
$netSum += $sum;
fwrite($fp, $sum);
}

// Clean up
fclose($fp);

// Create the day file
file_put_contents(date('Y-n-j') . '.txt', $netSum);
?>

 

I didn't test it, but you get the gist of it.

this looks really promising but I got an error on line 10

 

Parse error: syntax error, unexpected '&', expecting T_VARIABLE or '$'

 

Line 10 says:

foreach($fileNames as &$fileName) {

 

Any ideas? Btw, Im using php4.

[genericnumber1]

Ah, php4 doesn't support foreach references, you'll need to remove the &. There may be some other issues as I can't recall if any functions I used are php5 only. All the more incentive for you to figure out what the code does before using it!

[trauch]

I removed the & and it seems to be adding the individual text files. Unfortunately php4 also does not recognize file_put_contents. Do you know how to do this with fwrite or some other way with php4?

[trauch]

With the help of genericnumber1 I'm almost there but I would appreciate any input.  Since Im using php4 I cant use file_put_contents and am still trying to figure out how to save the file as the current date (2008-12-22.txt). I know I have to use fwrite but am not sure how to do this.

 

Here's what I have thus far.

 

<?php
// Make an array of the filenames to sum
$fileNames = array('textfile.txt', 'textfile2.txt', 'textfile3.txt');

// Open the file and zero out the net sum
$fp = fopen('textmaster.txt', 'a');
$netSum = 0;

// Add the numbers and append to the file
foreach($fileNames as $fileName) {
   $content = str_replace(' ', '', file($fileName)); 
   $sum = array_sum($content);
   echo 'Sum of "' . $fileName . ': ' . $sum;
   $netSum += $sum;
   fwrite($fp, $sum);
}

// Clean up
fclose($fp);

// Create the day file
fwrite(date('Y-n-j') . '.txt', $netSum);
?>

why don't you just update your PHP?

[trauch]

I wish I could. Im on a shared server and my host has control over upgrading so...

I see, maybe this will help: http://www.phpied.com/file_get_contents-for-php4/

I promise the answer is here look and you shall find!

[trauch]

all I can say is WOW!

 

Thanks
