I have the following code sample

private $analyze_types = array(
    "1" => array(
        'level' => '4',
        'l1' => '-1',
        'l2' => '-1',
        'l3' => '-1',
        'l4' => '-1',
        'l5' => '-1'
    ),
    "226" => array(
        'level' => '-1',
        'l1' => '-1',
        'l2' => '-1',
        'l3' => '2',
        'l4' => '3',
        'l5' => '4'
    )
);

How can i get value of "1" and if I want to get 'level' value, what should i do?

Don't think I understand your question. Can you be more detailed? –  aarryy Oct 10 '13 at 14:54
    
Well, I have a protected function in the same class with this array. And I want to get 1 and 226 in this case. –  FreshPro Oct 10 '13 at 14:55
    
@FreshPro: Are you looking for array_keys or something similar? –  Jon Oct 10 '13 at 14:56
    
what's the criteria to fetch the result when you say you want to get 1 and 126? –  aarryy Oct 10 '13 at 15:01
    
Well I'll fetch results and I need 1 and 226 to compare if fld_type=1 or fld_type=226 exists in database and if not i will insert inner array values in database that's why i'm asking –  FreshPro Oct 10 '13 at 15:03

PHP :

foreach( $this->analyze_types as $key => $value) {
  echo $key; // output 1 and 226
  echo $value['level']; // output 4 and -1
}

To get element with index 'level' of subarray with index '1' in main array you should use just

$this->analyze_types[1]['level']

Ok that gives me 4 thats good but how to get the "1" –  FreshPro Oct 10 '13 at 15:01
    
@FreshPro So array_keys($this->analyze_types) as other people suggested –  zavg Oct 10 '13 at 15:04

You can get the keys of an array by doing the following, if that's what you're asking?

$keys = array_keys($this->analyze_types);
print_r($keys);

Now that you have an array of keys you can simply loop through them to execute more code, for example:

foreach($keys as $k) {
    echo $k; //This will echo out 1
}
