Question

issue:

$a = array("a" => "1", "b" => "2");
print_r($a);

output:

Array = ([0]=>'1'
         [a]=>'1'
         [1]=>'2'
         [b]=>'2')

but what I want is like

Array = ( [a]=>'1'
          [b]=>'2')

Any suggestions?

Quote from the manual

By using MYSQL_BOTH (default), you’ll get an array with both
associative and number indices. Using MYSQL_ASSOC, you only get
associative indices (as mysql_fetch_assoc() works), using MYSQL_NUM,
you only get number indices (as mysql_fetch_row() works).

Unless you tell mysql_fetch_array to return associative, then it will return both enumarated and associative entries for each column

specify MYSQL_ASSOC as the second argument to your mysql_fetch_array to fix this problem

In the longer term, I’d also recommend dropping mysql and using mysqli or even pdo
