object - PHP - How to call method from a variable -


i hope may able me out. building scrape script using simple html dom.

i have few sites need thumbnail path, name of movie , other stuffs. have build me admin panel save in plaintext methods required find stuff based on matching pattern.

eg.

$movie_name = $result->children(0)->children(0)->innertext;

this works supposed work when save children(0)->children(0)->innertext in database , variable, eg,

$variable = "children(0)->children(0)->innertext"; $movie_name = $result->$variable;

it not work.

i pretty sure going horribly wrong this, please give me hint how save methods in plaintext , call them.

it must stored in plaintext because dom changing able keep it.

best regards.

you're looking php eval() function:

$movie_name = $result->eval($variable);

having said that, warned eval evil.

instead, recommend xpath.

hope helps!
