sql server - Issue with connection to MSSQL from PHP -


i'm having problems putting data mssql php - error:

sqlsrv_query() expects parameter 1 resource, boolean given in [path] on line 13

i can't see problem is, or if have syntax error.

<?php     $host = "127.0.0.1";      $dbusername = "humid";      $dbpassword = "humid";       $db = "test";     $t = $_get['t'];     $h = $_get['h'];       $connectioninfo = array("uid" => $dbusername, "pwd" => $dbpassword, "database" => $db) or die("couldnt connect server");     $dbconnect = sqlsrv_connect($host, $connectioninfo);     $sql = "insert historic values(null,$t,$h,current_timestamp)";     sqlsrv_query($dbconnect, $sql); ?>

any appreciated! i'm not familiar mssql, mysql

okay, i've enabled error messages, , i've got 1 now:

array ( [0] => array ( [0] => 42000 [sqlstate] => 42000 [1] => 126 [code] => 126 [2] => [microsoft][odbc driver 11 sql server][sql server]invalid pseudocolumn "$t". [message] => [microsoft][odbc driver 11 sql server][sql server]invalid pseudocolumn "$t". ) )

however, have no idea be? because $t sql syntax don't know of? long story short, i'm building temp , humid logging device arduino, , need post values db (using php) - syntax php looks this:

test.php?t=1&h=2

what have done wrong now? when testing on mysql server private, worked fine >_<

-- edit, solution found! --

okay, found solution, i'm not sure if of other answers had direct fix, however. mssql apparently doesn't accept "null" mysql does. ofc. last thing edited, i'm not sure if there errors in prior code. hoever, below final (and working) code. arduino posts , everything. eureka!

<?php     $host = "wdkto560\test";      $dbusername = "humid";      $dbpassword = "humid";       $db = "test";     $t = $_get['t'];     $h = $_get['h'];        $connectioninfo = array("uid" => $dbusername, "pwd" => $dbpassword, "database" => $db) or die("couldnt connect server");     $dbconnect = sqlsrv_connect($host, $connectioninfo);     $sql = "insert historic (temperature, humidity, date) values($t,$h,current_timestamp)";     sqlsrv_query($dbconnect, $sql) or die( print_r( sqlsrv_errors(), true)); ?>

sqlsrv_connect() failing connection , returning false. have debug it.

  1. check if database , username correct .
  2. user has access permission write database
  3. you have installed mssql driver php.

hope helps.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
