Hi

I want to send the data from a form to a file
but I first want to put that data into an array
and then send the array to the file

I need it so when I read the data from the, to put it again in an array
I don't know if this is possible thou


this is what I have so far

CODE
<?php
$bestand = 'test.txt';
$file = fopen($bestand, 'a+') or die('Bestand kon niet geopend worden!');

$naam = "".$_POST['naam']." ";
$voornaam = "".$_POST['voornaam']." ";
$adres = "".$_POST['adres']." ";
$pcode = "".$_POST['pcode']." ";
$woonplaats = "".$_POST['woonplaats']." ";
$telnr = "".$_POST['telnr']."<br />";

$gegevens = array($naam,$voornaam,$adres,$pcode,$woonplaats,telnr);

fwrite($file, $gegevens) or die('Kan niet schrijven naar bestand!');
fclose($file);

$fileread = 'test.txt';
$data = file($fileread) or die ('Kon bestand niet lezen');

foreach($data as $array){
echo $array;
}
?>


but the problem is, I only get the word 'Array' on screen
nothing else.



I want the data from that file again in an array when reading it.
Is this possible?




/EDIT
The language of the variables is Dutch
I'm sorry for that

You are getting this because you are referencing the entire array, & not the unique keys inside of the array.

CODE

print_r($gegevens);

I'm sorry, but I don't understand.
how can I use the print_r() function?
I only want to write that array to a file.


I tried something like this:

CODE
$gegevens = array($naam,$voornaam,$adres,$pcode,$woonplaats,telnr);
$test = print_r($gegevens);

fwrite($file, $test) or die('Kan niet schrijven naar bestand!');



I get this as output:
QUOTE
Array ( [0] => name [1] => myname [2] => some street [3] => 1111 [4] => Hoboken [5] => telnr ) 1


BUT, I get only a '1' in my file.



I'm not that experienced in PHP coding.
I'm still learning.
Can you please be more specific. smile.gif

Try this.
CODE
<?php
$arr=array("blah1","blah2","blah3");
$fp=fopen("test.txt","w+");
foreach($arr as $key => $value){
fwrite($fp,$value."\t");
}
?>

Hope it helps. smile.gif

yeah...
that worked. Thank you.
I can write an array to a file.

But the rest didn't work as expected.
I wanted to write to it with TR and TD tags and when I read from that file, that everything is in a nice table
But I will figure it out, I hope tongue.gif


Thans again smile.gif

hello,

i am a new member to the forum. i have some (very little) experience with php.

i tend to code in languages such as fortran where saving arrays to files and then injecting them back into an array is straight-forward.

suppose we're following what's gone on in this thread here.

so suppose i have used the following code to save an array to a text file:

CODE
<?php
$arr=array("blah1","blah2","blah3");
$fp=fopen("test.txt","w+");
foreach($arr as $key => $value){
fwrite($fp,$value."\t");
}
?>


and suppose i want to open the file and recreate the identical array that i originally saved.

what sort of straight-forward code could i use to do this?

many many thanks!

is so many ways, one small example.

php

<?php  
  
$arr=array("blah1","blah2","blah3");
file_put_contents("test.txt",implode(",",$arr));

$file_c = file_get_contents("test.txt");
$colms = explode(",",trim($file_c));
print_r($colms);

?>

i suppose one more question ... how can i get this to work with a 2dimensional array? is it easier to stick with a 1dimensional array?

that easy to, but ease is relative.
i have done may types.

use them sontimes to cashe DB results, for different reasons

question is, what kind ya want?

my prefered method is to store in a *.inc as an array, and include it.
