如何使php匹配正则表达式不匹配行？

Question

My code is

preg_replace("/([^; ]+)=>([^; ]+)/", "ec_set('$1',$2);", $input_lines);

on matching the following text

test=>1; test; test=>123; 

asdf
test=>[[test]]

The result

is outputting over-lines

ec_set('test',1);; test; ec_set('test',123);; ec_set('

asdf
test',[[test]]);

How to make it

ec_set('test',1);; test; ec_set('test',123);; 

asdf
ec_set('test',[[test]]);

?
