multidimensional array problem

[croakingtoad]

Okay, so I have been working on this but am 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]

Here's the output--
[code]
  1 =>
  array (
    0 => '20051230194116769413000000',

It may be better to write the output to a second array instead of trying to write back to the original.

[code]$_arr2 = array();

for ($i = 0; $i <= count($_arr); $i++) {
    foreach($_arr[$i] as $key => $row) {
        if($key != 0) {
            if (strpos($row, '|') !== false) {
                $_arr2[$i][$key] = explode('|', $row);
            }
            else {
                $_arr2[$i][$key] = $row;
            }
        }
    }
}

echo '<pre>', print_r($_arr2, true), '</pre>';[/code]

I'm getting this error--

Warning: Invalid argument supplied for foreach() in /home/hunter/public_html/cron/csv2arrayManual.php on line 13

Any idea what's causing it?

[code]<?
// csv to array parser
include_once '../classes/class.csv.php';
$document = 'rva-1.20060313.1107.dat';

$csv = & new csv("$document", ',', '"' , '\\');
$_arr = $csv->csv2Array();
$_arr2 = array();
//echo '<pre>' . var_export($_arr,true) . '</pre>';


for ($i = 0; $i <= count($_arr); $i++) {
    foreach($_arr[$i] as $key => $row) {
        if($key != 0) {
            if (strpos($row, '|') !== false) {
                $_arr2[$i][$key] = explode('|', $row);
            } else {
                $_arr2[$i][$key] = $row;
            }
        }
    }
}

echo '<pre>', print_r($_arr2, true), '</pre>';
//print_r($_arr[5][137][1]);  // this one works

?>[/code]

you have used count($arr) in your for loop!!! (For future refence that is very slow as count() will be evaluated each time you loop - set a counter = count before the loop and use that instead.)

Now that does not stop the script working but maybe there


try this

[code]
<?php
$i = 0;
foreach ($arr as $arr1) {
foreach ($arr1 as $key => $cont) {

   if (strpos($cont, '|') !== false  && !is_array($cont)) {
    $_arr2[$i][$key] = explode('|', $cont);
   } else {
    $_arr2[$i][$key] = $cont;
   }
  
}
$i++;
}
?>
[/code]

I am not entirly sure why you check to see if the key is not 0 in your script.

[wickning1]

"foreach($_arr[$i] as $key => $row) {"

The error you're getting happens when $_arr[$i] is not an array. It can also happen if $_arr[$i] has not been set. Try putting "print_r($_arr[$i]);" just before the foreach.
