Question

I send a QueryString formatted text like bellow to a php Script via Ajax:

title=hello&custLength=200&custWidth=300  

And I want to

Answer 1

I realize this is old, but I've found the most concise and effective solution to be the following (assuming you can't just encode the $_GET global):

parse_str('title=hello&custLength=200&custWidth=300', $parsed);

echo json_encode($parsed);

Should work for any PHP version >= 5.2.0 (when json_encode() was introduced).

Answer 2

$check = "title=hello&custLength=200&custWidth=300";
$keywords = preg_split("/[\s,=,&]+/", $check);
$arr=array();
for($i=0;$i<sizeof($keywords);$i++)
{
$arr[$keywords[$i]] = $keywords[++$i];
}
$obj =(object)$arr;
echo json_encode($obj);

Answer 3

The easiest way how to achiev JSON object from $_GET string is really simple:

json_encode($_GET)

this will produce the following json output:

{"title":"hello","custLength":"200","custWidth":"300"}

Or you can use some parse function as first (for example - save all variables into array) and then you can send the parsed output into json_encode() function.

Without specifying detailed requirements, there are many solutions.
