php - Doctrine DQL execute passing params -

-

i used dql in doctrine

$q->update('product') ->set('quantity','?') ->where('id=?'); $q->execute(array(20,5));

i check server query , generated sql

    update product set quantity = '20', updated_at = '5'  (id = '2010-04-26 14:34);

so need know why arguments aren't in correct places?

i got caught exact same bug myself few days ago. believe it's caused bug in timestampable behavior. i'm guessing have enabled in product model, , doctrine adds updated_at field series of fields update (set) , doesn't pay attention fact have sql parameters after (in clause). bug never comes when doing selects because timestampable isn't involved.

the solution found supply parameters build query rather in execute's array parameter , doctrine won't confused. this:

$q->update('product')  ->set('quantity', 20)  ->where('id = ?', 5); $q->execute();

however if need run same query many times different values, you'd losing performance benefits of separate prepare & execute phases. appears solution.

potentially better solution without performance loss: have not verified this, however, hope bug not surface if used named parameters instead of anonymous ? placeholders. doctrine's support named parameters described here: http://www.doctrine-project.org/documentation/manual/1_2/en/dql-doctrine-query-language

edit: have since tried alternate approach named parameters , unfortunately bug remains. doctrine gives error saying can't mix named , anonymous parameters in same query. should have been fixed long time ago imo.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
