Question

Array ( [0] => Array ( [No.,"Ticker","Company"] => 
                        1,"A","Agilent Technologies Inc." ) 
        [1] => Array ( [No.,"Ticker","Company" ] => 
                        2,"AA","Alcoa, Inc.") 
      )

This is the output when i type print_r($arrayOne);
What can I do so I can only get the Company column i.e. Agilent Technologies Inc, and Alocoa, Inc.

I tried echo $arrayOne[‘Company’] and $arrayOne[0][‘Company’] but it just outputted ‘Array’.

Answer 1

What you have is an outer array with two sub-arrays, each of which has only one value. Its key is the description of the 3 columns, and its value is the CSV value. If you have PHP 5.3, use str_getcsv() to parse it and return the third column

// Loop over the outer array
foreach ($arrayOne as  $subarr) {
  // Loop over the sub-arrays (though your sample only has one value each)
  // could also use array_pop()
  foreach ($subarr as $key => $csvstring) {
    // $csvstring holds the CSV value like  '1,"A","Agilent Technologies Inc."'
    // Parse it with str_getcsv()
    $cols = str_getcsv($csvstring);
    // Company name is the 3rd value, key [2]
    echo $cols[2] . "\n";
  }
}

For example with the input:

$arrayOne = array(
  array('No.,"Ticker","Company"' => '1,"A","Agilent Technologies Inc."' ), 
  array('No.,"Ticker","Company"'  => '2,"AA","Alcoa, Inc."') 
);
// The above loop prints:
Agilent Technologies Inc.
Alcoa, Inc.
