A question about using a text file as a PHP Array.

[cuboidgraphix]

Hi,

Quick question...  Can a text file with a bunch of numbers be used as an array for PHP? The thing is that I want to use this php script.

 

<?php
$HLR = array('A','B','H','J','K','L','M','P','T');
$VLR = array('A','B','L','T');

$Difference = array_diff($HLR, $VLR);

print_r($Difference);

echo '<br /><br />' . implode(', ', $Difference); 
?>

 

But instead of 'A','B', etc...  I want to use a text file  HLR.txt.

Inside this text file I'll have numbers like... 

6701001

6701231

6701343 .... and so on.  thousands of numbers. Each line is a different number.

 

So in conclusion, can a text file with a whole bunch of numbers be converted into an array or read as an array for PHP?

 

Thanks..  Awaiting patiently for your replies.

Yes. The function file() returns an array with every line of the file having an index in the array.

Thanks, but I don't think you quite understood what I was looking for.  The PHP Script I have there isn't exactly what I'm using. the arrays are in a text file. eg: HLR.txt  and VLR.txt .

 

I'm trying to find out if those two text files can be called to the php script and USED as arrays.

 

In lame man's terms.  I have two text files in my Hard Drive. I want to use a php page that will upload the two text files using a form, and run the script.  My question is ... is this possible?  Using the Two text files as arrays?  And if so, how ... through a different script?

[Daniel0]

Am I correct in believing that if the file looks like this:

6701001
6701231
6701343

then you want an array which looks like this?

$array = array(6701001, 6701231, 6701343);

 

That will turn the file into an array so to speak.

[cuboidgraphix]

Yes.  I'm sorry, I saw the code in your signature and I thought you were giving me that code.

One thing to watch when using file() - the linefeeds aren't stripped, so the array will actually be

 

array("6701001\n", "6701231\n", "6701343\n");

solution:

str_replace("\n", "", $data);

OK guys, I'm not sure how much damage I've caused, but this is what I have.  It ain't working for sh*t. 

 

<!-- Form Start -->  
<form name="form" method="POST" action="<?=$PHP_SELF?>">
Get Difference Between: 
HLR <input name="hlr" type="file" id="hlrfile" size="20" /> and 
VLR <input name="vlr" type="file" id="vlrfile" size="20" />
<input type="submit" name="execute" value="Execute" />
</form>                        
<?php
$h = @$_GET['hlr'];
$v = @$_GET['vlr'];	
$hl = fopen("$h", "r");
$vl = fopen("$v", "r");
$hlr = str_replace("\n", ",", $hl);
$vlr = str_replace("\n", ",", $vl);		
$harray = array("$hlr");
$varray = array("$vlr");

$diff = array_diff($harray, $varray);			
print_r($diff);			
//echo '<br />' . implode(', ', $diff); 
?>

 

Am I on the right track?

not really. do you need to upload the files or will they definitely be located in the same directory as the script? you have a little of both in there.

 

 

[cuboidgraphix]

hehehe.

 

Well what I really wanted is to browse in my hard drive, and not really upload it but just run the script on those two files.  Do I need to upload them first?

yes. PHP is a server-side language, so for it to analyze a file on your hard drive you must upload it to the server. It might be possible for PHP to connect to your server and retrieve the file itself, but you don't want to go there. you want to upload the files and have PHP compare them on the server.

this works for me:

 

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$hrname = 'hlrfile.txt';
$vrname = 'vlrfile.txt';

copy($HTTP_POST_FILES["hlr"]['tmp_name'],"./$hrname") or die("failed to copy hlr");
copy($HTTP_POST_FILES["vlr"]['tmp_name'],"./$vrname") or die("failed to copy vlr");

$hrarray = file($hrname);
$vrarray = file($vrname);

str_replace("\n","",$hrarray);
str_replace("\n","",$vrarray);

print_r($hrarray);
echo "<BR>";
print_r($vrarray);
}
?>
<HTML>
<BODY>

<form name="form" method="POST" action="<?=$PHP_SELF?>" enctype='multipart/form-data'>

Get Difference Between: 
HLR <input name="hlr" type="file" id="hlrfile" size="20" /> and 
VLR <input name="vlr" type="file" id="vlrfile" size="20" />

I tried your code, and it did not work. Is there something I have to modify?

[BlueSkyIS]

you need to make sure that the permissions are correct on the directory where the script resides, so that PHP is allowed to upload a file there. chmod to 755 first. if that doesn't work, try 777.

Hi again guys, Well i have a code that works whenever I have numbers like.... 

 

1

2

3

4

5

6

7

8

9

10

11

etc...

 

But it does not seem to work when I have numbers such as,

 

2800001

2801000

2801010

2801011

2801012

2810123

6600000

6701050

6701052

 

Can you see if anything is wrong with my code?

 

<?php
// Array Difference Script
$hlr = @fopen('hlr.txt', 'r');
if ($hlr){
$array1 = explode("\n", fread($hlr, filesize("hlr.txt")));
} 

$vlr = @fopen('vlr.txt', 'r');
if ($vlr){
$array2 = explode("\n", fread($vlr, filesize("vlr.txt")));
}

$diff = array_diff($array1, $array2);
foreach ($diff as $value){
  echo $value . " 
";
} 	
?>
