database - mysql PDO how to bind LIKE -

-

in query 

select wrd tablename wrd '$partial%'

i'm trying bind variable '$partial%' pdo. not sure how works % @ end.

would 

select wrd tablename wrd ':partial%'

where :partial bound $partial="somet"

or 

select wrd tablename wrd ':partial'

where :partial bound $partial="somet%"

or entirely different?

+1 karim's answer covers it. say:

"select wrd tablename wrd concat(:partial, '%')"

to string joining @ mysql end, not there's particular reason in case.

things bit more tricky if partial wrd looking can contain percent or underscore character (since have special meaning operator) or backslash (which mysql uses layer of escaping in operator — incorrectly, according ansi sql standard).

hopefully doesn't affect you, if need case right, here's messy solution:

$stmt= $db->prepare("select wrd tablename wrd :term escape '+'"); $escaped= str_replace(array('+', '%', '_'), array('++', '+%', '+_'), $var); $stmt->bindparam(':term', $escaped);

(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...

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."
