php - Check if value exist in array and get array from multidimensional array -


i have below php array:

array (         [0] => array ( [policy_id] => 1 [category_id] => 5 [limit_amount] => 11.00 [limit_amount2] => 23.00 ),         [1] => array ( [policy_id] => 1 [category_id] => 7 [limit_amount] => 32.00 [limit_amount2] => 23.00 ),         [2] => array ( [policy_id] => 1 [category_id] => 4 [limit_amount] => 12.00 [limit_amount2] => 12.00 ) )

now want 2 things:

  1. want check if category_id = 7 exists in array or not, , if there.
  2. then complete array multidimensional array,

example, if category_id = 7 in array should output 

array ([policy_id] => 1 ,        [category_id] => 7 ,        [limit_amount] => 32.00,        [limit_amount2] => 23.00 )

i tried use in_array(), not required values,

thanks help,

you can use array_column before doing array_search (i assume data in $array):

$match = $array[array_search(7, array_column($array, "category_id"))];

if need first check whether entry exists, first check return value of array_search, , return distinctive when value not found, e.g. false:

$index = array_search(7, array_column($array, "category_id")); $match = $index === false ? false : $array[$index];

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
