php - remove double quotes from json encoded array -

   $sql = "select column_type information_schema.columns     table_name = 'mst_sim_data'              , column_name = 'status'";    $result = mysql_query($sql);    $row = mysql_fetch_array($result);    $enumlist = explode(",", str_replace("'", '', substr($row['column_type'], 5,     (strlen($row['column_type'])-6))));      foreach ($enumlist $key => $value) {         $list["'$value'"] = $value;     }            return json_encode($list);   

this returns following json string.

object {'instock': "instock", 'issued': "issued", 'soldout': "soldout"} 

but need replace single quotes on double quotes , should this,

'instock': 'instock', 'issued': 'issued', 'soldout': 'soldout'} 

how can this?

is goal break json output? json strings , properties must use " quote.

i believe problem 2 fold

1. $list["'$value'"] = $value; should $list["$value"] = $value; and

2. the "s should left alone

if do wish mangle quotes (which means result not json), use result of

str_replace('"', "'", json_encode($list, json_hex_apos)) 

note json_hex_apos flag, prevent gross hack mutilating json-string embedded ' characters.
