Hello I'm trying to make it so it only show the items that are over $20 in a txt document.  This is the original code that stores it into a txt doc.

 

 

<? 
$arr=array('Sun Glasses', 'Jeans', 'T-shirt, 'Shoes', 'Wig');
$arr2=array('11.00', '2.00', '40.00', '50.00, '60.00');
$file=fopen("PERSON.txt","w+") or exit("Unable to open file!");



for($i=0; $i<=4; $i++){
fwrite($file, $arr[$i]."\t");
fwrite($file, $arr2[$i]."\n");
}


fclose($file);
?> 

 

 

Now this is what it looks like in the txt doc.

 

Sun Glasses 11.00

 

Jeans 2.00

 

T-Shirt 40.00

 

Shoes 50.00

 

Wig 60.00

 

All of that works fine..now this is what I have no idea how to do.  I have to make it list ONLY the items over $40.00, but it just comes up blank.

<?


$person = array();

$fh = fopen("PERSON.txt", 'r') or die("Can't open file");



while(!feof($fh))

  {

  $f = fgets($fh);

  array_push($person, $f);

  }

for ($i=0; $i<=4; $i++){
$arr = explode(' ', $person); 
fwrite($fh, $arr[$i]."\t");
fwrite($fh, $arr2[$i]."\n");
}

fclose($fh);



?>

 

I also know i need to echo it somehow. I'm just not sure. Any help would be appreciated!

Are you using the text file as a type of database? i.e. do you have your heart set on the format you have. It's easier to break things up if you use some kind of repeatable pattern like below.

 

sun glasses****20.00@@@@

Sun Glasses****11.00@@@@

Jeans****2.00@@@@

Yeah i've never even mess with a database. i have to get these file concepts down before i move onto them. im trying to teach myself and it is kinda hard

[Drippingblood123]

anybody? it shouldnt be too hard. i'm just a noob and am stuck

You seem to have no if statement to test the price of the array you are putting into the text file

and I you use a foreach  loop instead of a for loop it will make your code cleaner.

 

Something like this

 

for($i=0; $i<=4; $i++){
    if($arr2[i] > 20){
fwrite($file, $arr[$i]."\t");
fwrite($file, $arr2[$i]."\n");
}
}

[Drippingblood123]

oh is that the only thing i'm missing?

[Drippingblood123]

its not working

[emopoops]

you dont have anything about the 40 dollars in your code hon

[Drippingblood123]

I know. That's the only part I don't get how to do.

[emopoops]

no offense but database is easier to understand than files like this and wayy easier to do... just use a datbase.

[Drippingblood123]

I can't. Does anyone know how to do it without using a database?

yeah, give me a sec.

    $filename = 'filename.txt';
    $gtValue = 20;
    

    if (filesize($filename) > 0) {

$handle = fopen($filename, "r");

        $contents = fread($handle, filesize($filename));

        fclose($handle);
    }

    $seperate = explode("****", $contents);
   
    $item = array();

    $cost = array();

    foreach ($seperate as $value) { // Split the array by IP and last page refresh.
    
       list($item[], $cost[]) = split('@@@@', $value);
        
    }
    
    for ($i=0; $i < count($cost); $i++) {

if($cost[$i] < $gtValue) {
	unset($cost[$i];
	unset($item[$i];
}
    }

You'll need to modify your textfile to this format and it isn't built to catch problems like a misformated textfile.

 

sun glasses@@@@20.00****beans@@@@5.00****

[dbillings]

you'd be able to read the values by doing the following

 

for($i=0; $i < count($cost); $i++)

{

echo "Item: ".$item."  Cost: ".$cost;

}

[dbillings]

Here's a debugged version, but it won't display unless you have the proper format in your text file.

 

item@@@@cost****item2@@@@cost2****

 

<?php  
	$filename = 'filename.txt'; // adjust for correct makeshift db file
    	$gtValue = 20; // adjust for gt value
   

    	if (filesize($filename) > 0) {

   		$handle = fopen($filename, "r");

      		$contents = fread($handle, filesize($filename));

        	fclose($handle);
    	}

    	$seperate = explode("****", $contents);
   
    	$item = array();

    	$cost = array();

    	foreach ($seperate as $value) { 

   
       		list($item[], $cost[]) = split('@@@@', $value);
       
    	}  


for($x=0; $x < count($cost); $x++) {
	if($cost[$x] > $gtvalue)
	{
		echo "Item: ".$item[$x]."\n";
		echo "Cost: ".$cost[$x]."\n<br />";
	}
}
?>
