i have function accepts $filter argument , pulls data sql table based on filters in argument. @ first tried overloading function 1 function took single $filter variable , took array multiple filters. then, started wondering how sanitize filter tag. that may have been confusing here examples. example, user types in search box display users name john . so, $filter_tag set 'name' , $filter set 'john'. pdo query this: $query = "select `name` `users` "; $query .= $filter_tag." = ?"; the issue $filter_tag not sanitized. if sanitize , variable escaped, query not work. maybe making more complicated needs , there simple solution. please comment if not understand asking. you create whitelist of valid tags: if (in_array($filter_tag, ['name', ...], true)) { $query .= $filter_tag . = '?'; } alternately remove invalid characters, prefer whitelist approach, because there many valid column names :) lastly, instead ...

this w3school says strpos() function : returns position of first occurrence of string inside string, or false if string not found. how function defined? possible write such functions returns values of 2 different datatypes in other languages well? many dynamically typed languages allow return whatever want function. typed languages don't. in php function can return anything wants, including booleans, ints, strings, null, arrays, kinds of objects, whatever need. it's same in example javascript , lua, dynamically typed. just make sure check return type of function if can different kinds of things. things int(0) , false, considered equivalent if use == comparison. use === make sure it's right type.

i busy webshop, , have issue: i display quantity of products, , attribute of product. like: 2,4 cm 2,56 dm now want round numbers of variable, if use: $qty = round($_product->getbundle_qty()); but if use: $aantal = $_product->getbundle_qty(); works okay, doesn't round. then attribute doesn't show anymore ( dm, cm, m etc) can me? is $_product->getbunlde_qty() double or float? or string? in case, can use: $qty = round(floatval($_product->getbundle_qty())); edit: if want keep cm / dm in behind string can take string , explode @ spaces, creating array string. last value in array 'cm' or 'dm' text. $qtypieces = explode(" ", $_product->getbundle_qty()); //explode @ space $qtypiecescount = count($qtypieces); //count pieces $qty = round(floatval($_product->getbundle_qty())) . " " . $qtypieces[$qtypiecescount - 1]; //get last value in array, count minus 1 because start counting 0

i'm new haskell. it's nice far, i'm running copy-pasting quickcheck properties, , i'd fix that. here's made-up example: prop_myfunc :: [int] -> (int,int) -> bool prop_myfunc ints (i,j) = ints !! == ints !! j this won't work because quickcheck generates negative numbers, get *** failed! (after 2 tests , 2 shrinks): exception: prelude.(!!): negative index i've tried google solutions this, , i've found e.g. nonnegative , ==>, don't understand how work. how can restrict above example , j never negative? , also, neither high? is: 0 <= i,j < length ints constraining wrappers (from test.quickcheck.modifiers , if aren't reexported implicitly) can used in way: prop_myfunc :: [int] -> (nonnegative int, nonnegative int) -> bool prop_myfunc ints (nonnegative i, nonnegative j) = ints !! == ints !! j you can treat somewrapper a a modified distribution. example, nonnegative a ...
