passwords - PHP password_hash error -


i have been trying understand password salting , hashing project working on. responses previous question saw php manual password_hash way start.

however, when trying out code on page, error haven't been able resolve.
code: 

<?php /**  * note salt here randomly generated.  * never use static salt or 1 not randomly generated.  *  * vast majority of use-cases, let password_hash generate salt randomly  */ $options = [ 'cost' => 11, 'salt' => mcrypt_create_iv(22, mcrypt_dev_urandom), ]; echo password_hash("rasmuslerdorf", password_bcrypt, $options)."\n"; ?>

error:

parse error: syntax error, unexpected '[' in /home/content/##/######/html/testingfolder/hashnsalt.php on line 8

according manual - 

the above example output: $2y$11$q5mkhsbtlsjcnevsyh64a.acluzhngog7tqakvmqwo9c8xb.t89f.

line 8 

 $options = [

can here explain why getting error - since have copied , pasted test page php manual itself? still in stages of learning authentication/ php etc , depend on manual, stackexchange/overflow understand why things don't work way should. totally stumped when code find in manual doesn't work way should!

not security issue, syntax one.

the short array syntax:

$options = [ ... ];

is php 5.4 feature... had array( ... ).

you don't have 5.4 installed. password_hash php 5.5 feature you'll need update php version.

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
