Creating test-1.txt when test.txt already exists

[scrappy1855]

I'm can't seem to find anything on filename handling in php . I am needing to not append to my baddebt.txt file but create a new baddebt-1.txt, baddebt-2.txt, baddebt-3.txt depending on how many queries are submitted.  I was hoping that i could get some advice. Here is my code that is now working thanks to some other help on this forum. However i realized another problem for if someone submits 2 queries in a row it won't be able to handle creation of multiple txt files.

 

 

<?php

 

error_reporting(E_ALL);

ini_set("display_errors", 1);

 

$customernumber = $_POST["customernumber"];

$yearwkstart = $_POST["yearwkstart"];

$yearwkend = $_POST["yearwkend"];

$email = $_POST["email"];

 

 

$file = "c:\asys_reports\baddebt.txt";

 

$values = "$customernumber\r\n$yearwkstart\r\n$yearwkend\r\n$ email\r\n";

 

IF (!isset($_POST["customernumber"])) {

 

if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {

$uri = 'https://';

} else {

$uri = 'http://';

}

$uri .= $_SERVER['HTTP_HOST'];

header('Location: '.$uri.'/index_files/baddebtquery.htm');

 

}

 

 

elseif (empty($customernumber) || empty($yearwkstart) || empty($yearwkend) || empty($email)) {

if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {

$uri = 'https://';

} else {

$uri = 'http://';

}

$uri .= $_SERVER['HTTP_HOST'];

header('Location: '.$uri.'/index_files/error.htm');

}

 

else {

$values = "$customernumber\r\n$yearwkstart\r\n$yearwkend\r\n$ email\r\n";

$fp = fopen($file, "w") or die("Couldn't open $file for writing!");

$numBytes = fwrite($fp, $values) or die("Couldn't write values to file!");

 

fclose($fp);

 

echo exec(

 

 

if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {

$uri = 'https://';

} else {

$uri = 'http://';

}

$uri .= $_SERVER['HTTP_HOST'];

header('Location: '.$uri.'/index_files/complete.htm');

}

 

?>

What you first need to do is determine what the last baddebt-X.txt file is

easy to understand way is

get all babble files into an array and natsort them then array_pop the last one and work on it

list($a,$b)=explode(".","baddebt-X.txt");

list($c,$d)=explode("-",$a");

$X=$d+1;

$new_file="baddebt-$X.txt";

if you loop through querys just increment $X++

and build a file new for each query.

 

This also assumes that the first file is baddebt-X.txt and would fail if there was just a baddebt.txt.

$baddebtFiles = glob('baddebt*');
$baddebtCount = sizeof($baddebtFiles);
echo "next: baddebt-$baddebtCount.txt";

I found another acceptable solution that did exactly what i wanted. Thank you to everyone for the help its been greatly appreciated.

 

Here's the working code:

<?php 

error_reporting(E_ALL); 
ini_set("display_errors", 1); 

$customernumber = $_POST["customernumber"]; 
$yearwkstart = $_POST["yearwkstart"]; 
$yearwkend = $_POST["yearwkend"]; 
$email = $_POST["email"]; 


$num=''; 
do{ 
  $file = 'c:\asys_reports\baddebt'.$num.'.txt';   
}while(file_exists($file) && $num-->intval(PHP_INT_MAX+1)); 

$values = "$customernumber\r\n$yearwkstart\r\n$yearwkend\r\n$email\r\n"; 

IF (!isset($_POST["customernumber"])) {

if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) { 
$uri = 'https://'; 
} else { 
$uri = 'http://'; 
} 
$uri .= $_SERVER['HTTP_HOST']; 
header('Location: '.$uri.'/index_files/baddebtquery.htm');

} 


elseif (empty($customernumber) || empty($yearwkstart) || empty($yearwkend) || empty($email)) { 
if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) { 
$uri = 'https://'; 
} else { 
$uri = 'http://'; 
} 
$uri .= $_SERVER['HTTP_HOST']; 
header('Location: '.$uri.'/index_files/error.htm');
} 

else { 
$values = "$customernumber\r\n$yearwkstart\r\n$yearwkend\r\n$email\r\n"; 
$fp = fopen($file, "w") or die("Couldn't open $file for writing!"); 
$numBytes = fwrite($fp, $values) or die("Couldn't write values to file!"); 

fclose($fp);


if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) { 
$uri = 'https://'; 
} else { 
$uri = 'http://'; 
} 
$uri .= $_SERVER['HTTP_HOST']; 
header('Location: '.$uri.'/index_files/complete.htm'); 
}

?>

$num-->intval

 

This reminds me about a discussion on StackOverflow

 

intval(PHP_INT_MAX+1)

 

This is funny but no so funny as this:

 

PHP_INT_MAX+1
