Access php array index issue

Question

After use fgetcsv() function I get an array, then I use a foreach() and I get a "simple" associative array like:

Array  
(  
  [ix,radical,variant,simplified,pinyin,english,strokes] => 1,一,,,yi1,one,1  
)

Then I try to access any element and I fail:

 echo $record['ix'];

Notice: Undefined index: ix

echo next($record);  // return nothing!

Maybe is offtopic (not centred in php language) but I'm using some lib (not necessary of course from PHP commenter in http://php.net/manual/es/function.fgetcsv.php)

<?php

require "..\CsvImporter.lib.php";

$importer = new CsvImporter('my_route\\my.csv',true); 
while($records = $importer->get()) 
{   
    // debug
    print_r($records[0]);
    exit; 

    foreach ($records as $record)   
    {
      \\ ..
    }
}

And my screen output is

Array ( [ix,radical,variant,simplified,pinyin,english,strokes] => 1,一,,,yi1,one,1 )

My data:

ix,radical,variant,simplified,pinyin,english,strokes
1,一,,,yi1,one,1
2,丨,,,gun3,line,1
3,丶,,,zhu3,dot,1

So how is possible I'm unable to access any key ?

@Boctulus I think you probably want to show us your code how you tried to construct your array, because your key is not ix but ix,radical,variant,simplified,pinyin,english,strokes. Show: your current code to build this array and what you expect to get — Rizier123

Your array is not correct. Kindly review it again. That's a wrong format of array. Php dosent makes syntax error. — Panda

As you posted your data above. Your csv importer giving you each row with comma. So you need to explode it then use however you want to use

Example code \

 $i=0;
 while($records = $importer->get()) 
 {   
      if($i>0) //skip first row it is heading
      {
           $data = explode(',',$records);
           print_r($data);
          // now `$data[0]` contains `ix` value for your first csv row and so on
      }
      $i++;
 }

Thanks. I know how to do it in a lot of ways, but I was wondering why couldn't access that array in particular. Good answer anyway

I used some lib and the default delimiter was "\t" so something like 'ix,radical,variant,simplified,pinyin,english,strokes' was THE key and '一,,,yi1,one,1' the only value

Now, I see the problem I can do it easy:

$f = 'file.csv';
$separator = ',';

$file = file_get_contents($f);     

// bi-dimensional array
$regs = array_map(function($reg){return (explode($separator,$reg));},explode("\n",$file));

Thanks all!
