arrays - sed replace $_REQUEST["hello"] with functionName('hello') -

in old php app im still requesting parameters $_request, have function checks before returning.

so want variables $_request["hello"] replace function have _request('hello')

i tried following sed command, doesnt find $_request variables.

sed 's/$_request\["(.*)"\]/_request('\1')/g' 

i tried different things escaping $ char or changing regex (.*), not work. wrong on one?

i use command save time changing $_request vars function call.

try this:

$ cat file sed replace $_request["hello"] functionname('hello')  $ sed 's/\$_request\["\([^"]*\)"\]/_request('\''\1'\'')/g' file sed replace _request('hello') functionname('hello') 

you need use '\'' because ' breaks shell need provide literal ' in shell followed ' sed. changed .* [^"]* it'll stop @ end of string rather last " on line.
