I have a string - something like
$string = 'key1=value1, key2=value2, key3=value3';
How can I get an array from the given string like the following?
$array = array(
'key1' => 'value1',
'key2' => 'value2',
'key3' => 'value3',
);

If the values (text on the right side of the = symbols) do not have any characters with special meaning in a URL's querystring AND a value will never be null, then you won't have any unexpected results using parse_str() after converting the input to valid querystring format.
$string = 'key1=value1, key2=value2, key3=value3';
parse_str(
str_replace(", ", "&", $string),
$array
);
var_export($array);

A naive solution could be :
$string = 'key1=value1, key2=value2, key3=value3';
$array = array();
foreach (explode(', ', $string) as $couple) {
list ($key, $value) = explode('=', $couple);
$array[$key] = $value;
}
var_dump($array);
And you'd get the expected array as a result :
array
'key1' => string 'value1' (length=6)
'key2' => string 'value2' (length=6)
'key3' => string 'value3' (length=6)

This is exactly what parse_str do. In your case, you need to replace your commas with a &:
$string = 'key1=value1, key2=value2, key3=value3';
$array = parse_str(str_replace(', ', '&', $string));
// Yields
array(
'key1' => 'value1',
'key2' => 'value2',
'key3' => 'value3',
)

$a = explode(', ', $string);
$array = array();
foreach($a as $v){
$x = explode('=', $v);
$array[$x[0]] = $x[1];
}
