problem with array

[croakingtoad]

Okay, so I have this multidimensional array that looks something like--
[code]
[1] => Array ( [0] => 20051230194116769413000000 [1] => 20060310195836868674000000 [2] => 00 [3] => 500169 [4] => Y [5] => 20060310190340772208000000 [6] => [7] => 19990816212109142258000000 [8] => Residential [9] => Single Family [10] => 2005-01-04 [11] => [12] => [13] => [14] => [15] => Active [16] => [17] => [18] => [19] => [20] => [21] => [22] => 69950.00 [23] => [24] => [25] => [26] => [27] => [28] => [29] => 5 - Northwest Roanoke City [30] => [31] => 1303 [32] => [33] => [34] => HANOVER [35] => [36] => NW [37] => AVE [38] => [39] => Roanoke [40] => VA [41] => Roanoke City [42] => [43] => 24017 [44] => [45] => [46] => [47] => [48] => 768.00 [49] => 768.00 [50] => 0.00 [51] => 0.00 [52] => 0.00 [53] => 1949 [54] => Cape Cod [55] => [56] => 50 X 117 [57] => 0.00 [58] => [59] => [60] => [61] => [62] => [63] => [64] => [65] => 0 [66] => 2 [67] => [68] => 1 [69] => [70] => [71] => [72] => [73] => N/A [74] => [75] => 394.00 [76] => [77] => EUREKA LAND [78] => COMPLETELY REMODELED-NEW VINYL SIDING,NEW WINDOWS,NEW CARPET & VINYL NEW KITCHEN,NEW HEAT PUMP,NEW PAINT,WALKUP ATTIC COULD BE FINISHED INTO MORE ROOMS [79] => [80] => 2220506 [81] => [82] => 10TH ST TO RIGHT ON HANOVER HOUSE ON RIGHT [83] => [84] => [85] => [86] => Off Street Parking [87] => 2006-03-11 13:08:33.650667 [88] => Exclusive Right to Represent Seller [89] => No [90] => Crawl Space [91] => FRPK [92] => William Ruffner [93] => Fleming [94] => [95] => [96] => [97] => No [98] => 20060311031233373503000000 [99] => [100] => [101] => [102] => [103] => [104] => Y [105] => 20060310190150596090000000 [106] => [107] => [108] => 1303 [109] => -28655552 [110] => -16110225 [111] => [112] => Completed [113] => [114] => [115] => PTS 1&2 [116] => 2 [117] => 0 [118] => N/A [119] => [120] => [121] => 0.00 [122] => 2.00 [123] => 0.00 [124] => [125] => [126] => [127] => [128] => [129] => 0.00 [130] => [131] => [132] => [133] => [134] => [135] => EUREKA LAND [136] => Bedroom 1:||||Entry|;Bedroom 2:||||Entry|;Kitchen:||||Entry|;Living Room:||||Entry|; [137] => Lot Description|Up Slope|Yes;Construction|Vinyl|Yes;Miscellaneous Info|Single Wide|No;Miscellaneous Info|Double Wide|No;Heating|Heat Pump Electric|Yes;Cooling|Heat Pump Electric|Yes;Fireplace|# Fireplaces|0;Appliances|Refrigerator|Yes;Appliances|Range|Yes;Floors|Carpet|Yes;Floors|Vinyl|Yes;Windows|Tilt-In|Yes;Exterior Doors|Insulated|Yes;Porch|Front Porch|Yes;Water Description|Public Water|Yes;Sewer Description|Public Sewer|Yes;Bedrooms|Bedrooms Entry Level|2;Full Baths|Full Baths Entry Lvl|1; )
[/code]

Now if you look at [137] you will see it also contains an array with '|' as the delimiter. I have two questions. How do I get the value of [1] and how do I get the values of the array items within [137]?

As for how to get the value of [1] I have something like this-- $array[$key][1] but all that is giving me when I print_r it is "array[1]".

And I haven't the slightest idea where to begin on my second question.

Thanks for the help!

[obsidian]

well, as far as PHP is concerned, the value of [137] is still a string. you've got to change it to an array to be able to access it as an array. try something like this:
[code]
$array[137] = explode("|", $array[137]); // break it into an array
echo $array[137][1]; // now, you can access individual pieces.
[/code]

hope this helps!

[kenrbnsn]

No, index 137 of your array contains a string. To convert this into an array, do:
[code]<?php
$tmp_ary = explode('|',$array[137]);
echo '<pre>' . print_r($tmp_ary,true) . '</pre>';
?>[/code]

Okay, that makes sense but what about $array[1] ?

When I use this code
[code]
foreach($array as $key => $row) {
    print_r("$array[$key][0]<br />");
}
[/code]

It's just printing--

Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
Array[0]
etc....

[kenrbnsn]

You don't need to put "print_r" in a loop, just use:
[code]<?php echo '<pre>' . print_r($array,true) . '</pre>'; ?>[/code]

Good point.

Okay, back to my original problem that Obsidian and kenrbnsn dealt with.

I now have this code-
[code]
foreach($_arr as $key => $row) {
    if($key != 0) {
        $_arr[$key][137] = explode("|", $_arr[$key][137]);
        echo "$_arr[$key][137][0]<br />";
    }
}
[/code]

All this is giving me though is-
Array[137][0]
Array[137][0]
Array[137][0]

repeated over and over until the end of the loop. What am I doing wrong, why isn't it giving me the value of the array item?

Dude.. you don't have a multi dimensional array, at all.. You have a single dimension array.

Stop trying to [key][value].. its just Array[0] -> Array[137]

If you look at key [136] in my original post, you will see the multidimensional array csv'd with pipes |

This would be [$key][136][$whatever]
[code]
[136] => Bedroom 1:||||Entry|;Bedroom 2:||||Entry|;Kitchen:||||Entry|;Living Room:||||Entry|; [137] => Lot Description|Up Slope|Yes;Construction|Vinyl|Yes;Miscellaneous Info|Single Wide|No;Miscellaneous Info|Double Wide|No;Heating|Heat Pump Electric|Yes;Cooling|Heat Pump Electric|Yes;Fireplace|# Fireplaces|0;Appliances|Refrigerator|Yes;Appliances|Range|Yes;Floors|Carpet|Yes;
Floors|Vinyl|Yes;Windows|Tilt-In|Yes;Exterior Doors|Insulated|Yes;Porch|Front Porch|Yes;Water Description|Public Water|Yes;Sewer Description|Public Sewer|Yes;Bedrooms|Bedrooms Entry Level|2;Full Baths|Full Baths Entry Lvl|1; )
[/code]

[kenrbnsn]

As I said before, the entries with the "|" are just plain strings, you need to use explode() to turn them into an array.

This code
[code]<?php
foreach($_arr as $key => $row) {
    if($key != 0) {
        $_arr[$key][137] = explode("|", $_arr[$key][137]);
        echo "$_arr[$key][137][0]<br />";
    }
}?>[/code]
is not going to do what you want, which I think is to find all the values in the array that contain a "|" and replace them with an array. Try this:
[code]<?php
for ($i=0;$$ < count($_arr); $i++)
     if (strpos($_arr[$i] !== false) $_arr[$i] = explode('|',$_arr[$i]);
echo '<pre>' . print_r($_arr,true) . '</pre>';   // for debugging only
?>[/code]

[croakingtoad]

Ken, I'm not sure I understand what you're doing but that's my fault!

I made a breakthrough (I think) a bit ago, let me show you where I am--

[code]
foreach($_arr as $key => $row) {
    if($key != 0) {
        $_arr[$key][137] = explode("|", $_arr[$key][137]);
        print_r("$_arr[$key][137][1]<br />");   // this one doesn't...
    }
}

print_r($_arr[5][137][1]);  // this one works
[/code]

The print_r in the loop just prints "Array[137][1]" down the page, BUT, the print_r at the bottom actually prints the value of the array, which in this case is "Sloped".

What gives?

[kenrbnsn]

Can you post the results of this code:
[code]<?php echo '<pre>' . var_export($_arr,true) . '</pre>'; ?>[/code]
Put this line after the array is populated and before you do anything to it.

Ken

[croakingtoad]

Okay, here it is, I've cut out some of the middle because it's a really long array
[code]
1 =>
  array (
    0 => '20051230194116769413000000',
    1 => '20060310195836868674000000',
    2 => '00',
    3 => '500169',
    4 => 'Y',
    5 => '20060310190340772208000000',
.....
    135 => 'EUREKA LAND',
    136 => 'Bedroom 1:||||Entry|;Bedroom 2:||||Entry|;Kitchen:||||Entry|;Living Room:||||Entry|;',
    137 => 'Lot Description|Up Slope|Yes;Construction|Vinyl|Yes;Miscellaneous Info|Single Wide|No;Miscellaneous Info|Double Wide|No;Heating|Heat Pump Electric|Yes;Cooling|Heat Pump Electric|Yes;Fireplace|# Fireplaces|0;Appliances|Refrigerator|Yes;Appliances|Range|Yes;Floors|Carpet|Yes;Floors|Vinyl|Yes;Windows|Tilt-In|Yes;Exterior Doors|Insulated|Yes;Porch|Front Porch|Yes;Water Description|Public Water|Yes;Sewer Description|Public Sewer|Yes;Bedrooms|Bedrooms Entry Level|2;Full Baths|Full Baths Entry Lvl|1;',
  ),
[/code]

[kenrbnsn]

Thanks for posting the output.

What I missed (and I think everyone else missed) was the initial "1" pointing to an array, so all the code I posted couldn't work.

I took the output, cut & pasted it into a small script and came up with:
[code]<?php
$_arr = array(1 =>
  array (
    0 => '20051230194116769413000000',

    3 => '500169',
    4 => 'Y',
    5 => '20060310190340772208000000',
    135 => 'EUREKA LAND',
    136 => 'Bedroom 1:||||Entry|;Bedroom 2:||||Entry|;Kitchen:||||Entry|;Living Room:||||Entry|;',

  ),);
  
  echo '<pre>' . var_export($_arr,true) . '</pre>';  // before exploding the strings containing "|"
  foreach ($_arr[1] as $k => $v)
          if (strpos($v,'|') !== false) $_arr[1][$k] = explode('|',$_arr[1][$k]);
  echo '<pre>' . var_export($_arr,true) . '</pre>';  // after

Is this what you want?

Ken

[croakingtoad]

Yup...exactly. And then how would I access each subitem in [136] and/or [137]..

[kenrbnsn]

$_arr[1][136 or 137][$i] .... for $i from 0 to count($_arr[1][136 or 137]) or in code:
[code]<?php
for ($j = 136; $j<138; $j++)
     for ($i = 0; $i < count($_arr[1][$i]; $i++) {
           echo "we're now looking at: " . $_arr[$j][$i] . "<br>\n";
?>[/code]

Ken

[croakingtoad]

Okay, so I have been working on this but am still having problems. Basically what's happening is the loop is only exploding $_arr[1][136]. When it gets to $_arr[1][137] it doesn't explode it into an array and when it gets to any iteration beyond that it doesn't do either $_arr[2+][136] nor $_arr[2+][137]

What am I doing wrong here?

Here's the code I have--
[code]
for ($i = 0; $i <= count($_arr); $i++) {
    foreach($_arr[$i] as $key => $row) {
        if($key != 0) {
            if (strpos($row, '|') !== false) {
                $_arr[$i][$key] = explode('|', $_arr[$i][$key]);
                echo '<pre>' . var_export($_arr,true) . '</pre>';
            }
        }
    }
}
[/code]
