[SOLVED] multidemsional array

[Dorky]

hey, trying to get a 2d array down to top level as ending with /n and lower level divided by ||

 

like so in the flat file

linkname || linkurl.com

linkname || linkurl.com

linkname || linkurl.com

linkname || linkurl.com

Warning: implode() [function.implode]: Invalid arguments passed in

 

$rewritearray = implode("||" , $dumplinkdata[$dumplinkk]);

[Andy-H]

// does this show that $dumplinkdata[$dumplinkk] is an array?
var_dump($dumplinkdata[$dumplinkk]);

Array ( [1] => Array ( [0] => jknjk [1] => jn nj,n.com ) [2] => Array ( [0] => kjnkj [1] => ljknln ) ) Array ( [2] => Array ( [0] => kjnkj [1] => ljknln ) ) Array ( )

You want to use explode(), not implode(). implode() takes an array and makes a string, the opposite of what you want to do.

 

<?php
$file = <<<FILE
linkname || linkurl.com
linkname || linkurl.com
linkname || linkurl.com
linkname || linkurl.com
FILE;

$arr = array_map(create_function('$a', 'return array_map("trim", explode("||", $a));'), explode("\n", $file));
echo "<pre>";
print_r($arr);
echo "</pre>";

 

Output:

Array
(
    [0] => Array
        (
            [0] => linkname
            [1] => linkurl.com
        )

    [1] => Array
        (
            [0] => linkname
            [1] => linkurl.com
        )

    [2] => Array
        (
            [0] => linkname
            [1] => linkurl.com
        )

    [3] => Array
        (
            [0] => linkname
            [1] => linkurl.com
        )

)

no. i need to make

 

array([0] array( [0] , [1] ))

array([1] array( [0] , [1] ))

array([2] array( [0] , [1] ))

array([3] array( [0] , [1] ))

 

into

 

[0] || [1]

[0] || [1]

[0] || [1]

[0] || [1]

 

a string to put in a flat file.

 

linkname || linkurl

linkname || linkurl

linkname || linkurl

linkname || linkurl

 

with an unknown number of parent arrays

[Alex]

So like the opposite of what I did? I don't really follow what you're saying..

[Dorky]

no. i need to make

array([0] array([0] , [1] )) 

array([1] array([0] , [1] )) 

array([2] array([0] , [1] )) 

array([3] array( [0] , [1] ))


into

    [0] || [1]
    [0] || [1]
    [0] || [1]
    [0] || [1]


a string to put in a flat file.

linkname || linkurl
linkname || linkurl
linkname || linkurl
linkname || linkurl

with an unknown number of parent arrays

[Alex]

<?php
$arr = Array(
		Array('linkname', 'linkurl.com'),
		Array('linkname', 'linkurl.com'),
		Array('linkname', 'linkurl.com')
		);

$var = implode("\n", array_map(create_function('$a', 'return implode(" || ", $a);'), $arr));

[Andy-H]

$arr = array(
              0 => array('linkname1' => 'linkurl1.com'),
              1 => array('linkname2' => 'linkurl2.com'),
              2 => array('linkname3' => 'linkurl3.com')
            );
$str = '';
   foreach($arr as $v):
      foreach($v as $key => $val)
         $str .= $key . ' || ' . $val . "\n\r";
   endforeach;

   echo nl2br($str);

 

//EDITED, should display correct result now.

[Andy-H]

<!-- #Output -->
linkname1 || linkurl1.com
  linkname2 || linkurl2.com
  linkname3 || linkurl3.com

i see that would work but like i said the number of arrays will very. so i cant just simply reassign the arrays as is, it must be dynamic. im still looking around as well on google. nothing yet. funny, i would think this is commons.

I don't know what you're talking about.. My solution will work with any number of arrays..

[Dorky]

$arr = array(

              0 => array('linkname1' => 'linkurl1.com'),

              1 => array('linkname2' => 'linkurl2.com'),

              2 => array('linkname3' => 'linkurl3.com')

            );

is a determined number of arrays, i dont see how that applies to  an unlimited number of them.

if ($_GET['dump'] == "link" && $_SESSION['staff'] == "on")
{
$dumplink = $_GET['access'];
$dumplinkinfo = file("$dumplink.html");
foreach($dumplinkinfo as $dumplinkkey => $dumplinkval) 
{
   $dumplinkdata[$dumplinkkey] = explode("||", $dumplinkval);
}
for($dumplinkk = 0; $dumplinkk < sizeof($dumplinkinfo); $dumplinkk++) 
{
unset($dumplinkdata[$dumplinkk][0]);
unset($dumplinkdata[$dumplinkk][1]);
unset($dumplinkdata[$dumplinkk]);
}
$test = sort ($dumplinkdata);
print_r($test);
}

i need to get out of this the same thing i get with print_r

in the form of

 

$dumplinkdata[$dumplinkk][0] || $dumplinkdata[$dumplinkk][1]

 

final write to file should look like

That's just a static array for the example.. You can plug any other Array with any other number of elements and it'll work.

lmao. ok im not understanding. im really tired and near the end of this project. im not trying to p!$$ you off at all. if you could give me the tard breakdown i would greatly appreciate it.

$var = implode("\n", array_map(create_function('$a', 'return implode(" || ", $a);'), $arr));

 

First array_map() is preformed on $arr which is our multidimensional array. For every array it preforms implode(" || ", $a), which basically takes each array and implodes with a delimiter of " || ". So basically array_map() in this case overall returns an array of strings like "linkname || linkurl.com", finally the last implode() takes that array returned by array_map() and creates a string with a delimiter of "\n".

 

array_map()

create_function()

implode()

ok i got that. very cool man thx very very much. i am on coffee overload.

this is what i have and its doing what it needs to but it either isnt unseting the file or its adding link breaks. not sure yet but i have a line for each time i read , remove and replace.

if ($_GET['dump'] == "link" && $_SESSION['staff'] == "on")
{ 
$dumpthis = ereg_replace("[^A-Za-z0-9]", "", $_GET['dumplink']);
$dumplinkinfo = file("links.html");
foreach($dumplinkinfo as $dumplinkkey => $dumplinkval) 
{
   $dumplinkdata[$dumplinkkey] = explode("||", $dumplinkval);
}
for($dumplinkk = 0; $dumplinkk < sizeof($dumplinkinfo); $dumplinkk++) 
{
$check = ereg_replace("[^A-Za-z0-9]", "", $dumplinkdata[$dumplinkk][0]);
if ($check == $dumpthis)
{
unset($dumplinkdata[$dumplinkk][0]);
unset($dumplinkdata[$dumplinkk][1]);
unset($dumplinkdata[$dumplinkk]);
}
}
$linkvar = implode("\n", array_map(create_function('$a', 'return implode(" || ", $a);'), $dumplinkdata));
unlink("/home/p14tnue3/public_html/howton/links.html");
$fp = fopen("links.html", "a");
fwrite($fp, "$linkvar");
fclose($fp);
}

[Dorky]

hmm. idk. its just fine. i cleared all the white space and uploaded then deleted the links and its perfect. you are the man. thx for being patient.

Np, just remember to mark the topic as solved, there's a button at the bottom left to do this.
