PHP recursively calls the array value and uses it to execute the specified function

The following is the original wordpress code. To be lazy, modify it to apply other functions.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

/** * Navigates through an array and removes slashes from the values. * * If an array is passed, the array_map () function causes a callback to pass * Value back to the function. The slashes from this value will removed. * * @ Since 2.0.0 * * @ Param mixed $ value The value to be stripped. * @ Return mixed Stripped value. */ Function stripslashes_deep ($ value ){ If (is_array ($ value )){ $ Value = array_map ('stripslashes _ deep ', $ value ); } Elseif (is_object ($ value )){ $ Vars = get_object_vars ($ value ); Foreach ($ vars as $ key => $ data ){ $ Value-> {$ key} = stripslashes_deep ($ data ); } } Elseif (is_string ($ value )){ $ Value = stripslashes ($ value ); } Return $ value; }

The Code is as follows:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42
