PHP: Convert comma separated value pair string to Array -

i have comma separated value pairs , convert associative array in php.

example:

{     age:30,    weight:80,    height:180 } 

converted to:

echo $obj['weight']; // 80 

does make difference values not in inverted commas? mean: weight:80 vs weight:'80'

p.s. i've posted phone, don't have lot of fancy markup available make question more presentable.

http://php.net/manual/en/function.json-decode.php it's json object convert array.

$string = '{ "age":30, "weight":80, "height":180 }';  $array = json_decode($string, true); echo $array['age']; // returns 30 

provided given string valid json.

update

if doesn't work because string doesn't contain valid json object (because see keys missing double quotes), execute regex function first:

$string = "{ age:30, weight:80, height:180 }"; $json = preg_replace('/(?<!")(?<!\w)(\w+)(?!")(?!\w)/u', '"$1"', $string); // fix missing quotes  $obj = json_decode($json, true); echo $obj['age']; // returns 30 

when using regex above, make sure string doesn't contain quotes @ all. make sure not keys have quotes , not. if so, first rid of quotes before executing regex:

str_replace('"', "", $string); str_replace("'", "", $string);
