Preg Match PHP Expression to capture an array from text within {{STRING}}

Question

I have this string

$url = offer?offer_id={{offer_category_id}}&item{{offer_title}}

Is there a way how I can create a php array with the text inside the {{ }} thus resulting an array similar to

$array[0] = 'offer_category_id'
$array[1] = 'offer_title'

This is what I have but its not working as wanted

preg_match("/{{([^\"]*)\}}/", $url , $cols);

This code will give your values:

$str = 'offer?offer_id={{offer_category_id}}&item{{offer_title}}';
if ( preg_match_all('~{\s*{([^}]*)}~i', $str, $m) )
   print_r ( $m[1] );

OUTPUT:

Array
(
    [0] => offer_category_id
    [1] => offer_title
)

Use preg_match_all:

preg_match_all("/{{([^\"}]+)\}}/", $url , $cols);

Great Man ! Any idea why it outputted: Array ( [0] => Array ( [0] => {{offer_category_id}} [1] => {{offer_title}} ) [1] => Array ( [0] => offer_category_id [1] => offer_title ) )

What do you mean? $cols[1] will contain an array you need

i think it should be (you might need to play with the flag to get the desired order):

preg_match_all("/{{([^}]+)\}}/", $url , $cols, PREG_SET_ORDER);
