I'm using some PHPAGI in asterisk that are working on some servers. But when I used them in my new server they worked like usual for only 3 days and now they take longer than expected. Here is a sample.Any suggestion is appreciated.
#!/usr/bin/php -q
<?php
require('phpagi.php');
error_reporting(E_ALL);
$agi = new AGI();
$_callerId = $agi->get_variable("CALLERID(num)");
if(strlen($_callerId)>4)
{
$con=mysqli_connect(SomeServer);
$result = mysqli_query($con,"Select caller_id,extention from record_call order by id desc limit 50");
while($row = mysqli_fetch_array($result)) {
$tempCallerId = $row['caller_id'] ;
$tempExtention = $row['extention'] ;
if($tempCallerId==$_callerId)
{
$agi->set_variable('exExtention',$tempExtention);
mysqli_close($con);
return;
}
};
$agi->set_variable('exExtention','new');
mysqli_close($con);
?>
I got it. Connecting to MySQL took more than usual and it was because of the dns set in elastix. I removed it and now it's working as expected.

<?php
session_start();
$con = mysqli_connect('localhost', 'root');
mysqli_select_db($con, 'id12887901_visitor');
$query = "select * from curvis1 order by id desc limit 1";
$result = mysqli_query($con, $query);
$row = mysqli_fetch_array($result);
date_default_timezone_set('Asia/Hong_Kong');
$today = date("H:i:s");
echo $today;
if ($today == $row['end_at']){
$msg = "Visitor No.1 pass has expired.";
$reg = "insert into msg(comment) values('$msg')";
mysqli_query($con, $reg);
echo "WTF";
} else {
echo "LOL";
}
?>
I want it to run in the background. I've head of using ajax but alas I have not found an ajax solution in this. Any feedback will be appreciated thank you.
This is for a notification.
How do i call the server by ajax and asking frequently if there's any changes etc.
Cron did the job for me after learning it! sorry for the dumb question guys.
I'm new to PHP.
Now I'm trying to fix PHP source other one already have worked.
I succeeded to connect it with mysql using PEAR.
I'm on running it on my local, with MAMP and installed XDebug as well.
Here's the problem.
$select_query = " SELECT SEQ FROM TB_VISITOR WHERE VISITOR_NAME = '$visitor_name' AND VISITOR_PHONE_NO = '$visitor_phone_no' ";
$result =& $db->query($select_query);
if( PEAR::isError($result) )
{
$result_message['result'] = false;
$result_message['error_message'] = 'Search Fail';
}else
{
if( $result->fetchInto($row) )
{
$visitor_seq = $row[0];
}
}
I think that I'm blocked here, and want to know further what the problem was. What I want to see could be expressed in JQuery as 'console.log($result);
so I tried echo, echo $result > Never worked.
Of course, console.log never worked on PHP :'(
and with XDebug I tried like
phpinfo();
I got error message ? on PHP logs
phpinfo() expects parameter 1 to be integer, object given in /Applications/MAMP/htdocs/smartvisiting/visitor_enrollment_proc.php on line 54
so again tried phpinfo($result);
nothing happened.
Please let me know how I can see of 'result' in anyway.
I'm on using Chrome dev mode, Atom as editor tool, and running PHP through MAMP.
$select_query = " SELECT SEQ FROM TB_VISITOR WHERE VISITOR_NAME = '$visitor_name' AND VISITOR_PHONE_NO = '$visitor_phone_no' ";
$result = $db->query($select_query);
if (mysql_errno())
{
echo mysql_error();
}
else
{
if( $result->fetchInto($row) )
{
$visitor_seq = $row[0];
}
}
I have a successful connection to the database through this php script but it is not returning any values even though it is connected. I am checking for the results on my web browser and it just returns a blank screen. I have used the same script (different queries) to access two other tables in the database and they are both working fine. Here is my code:
<?php
$username = "xx";
$password = "xxx";
$host = "xxxxx";
$database="xxxxx";
$server = mysql_connect($host, $username, $password);
$connection = mysql_select_db($database, $server);
$myquery = "SELECT `AUTHOR`, `In_order` from `authors`";
$query = mysql_query($myquery);
if ( ! $query ) {
echo mysql_error();
die;
}
$data = array();
for ($x = 0; $x < mysql_num_rows($query); $x++) {
$data[] = mysql_fetch_assoc($query);
}
echo json_encode($data);
mysql_close($server);
?>
It is probably some silly mistake that I have over looked but I have been stuck on it for longer than I should! thanks in advance for any feedback
Tried you code locally on some data and it returns everything ok.
I needed to change the select to match my data
So I am 95% sure the problem is in your query / db settings.
I would first check if your columns in database is really called AUTHOR and 'In_order' with the exact capital letters.
MySql names can be case sensitive depending on your db server settings, and this could be the problem
Sidenote: if you can research mysqli and pdo for connecting to DB instead of mysql that is deprecated.
Try this:
$myquery = "SELECT `AUTHOR`, `In_order` from `authors`";
$query = mysql_query($myquery);
$num = mysql_num_rows($query);
var_dump($query);
var_dump($num);
echo mysql_error();
and tell us what it all says.
Edit: okay, so it's 231 rows in your table, as the var_dump($num) says. Now let's try and get them at last, but in a slightly more efficient way:
while ($row = mysql_fetch_assoc($query)) {
$data[] = $row;
}
echo json_encode($data);
I have a feeling that your "for" loop and mysql_fetch_assoc() inside is what plays tricks with you, because both of them use different internal counters.
Newbie question about PostgreSQL. I'm migrating a MySQL/PHP app I've created, hosted on a Linux server, to PostgreSQL/PHP on a MacOSX Lion Server environment. It's my first experience with Postgres. The first query I'm testing doesn't work as it returns nothing (not even an error message, whichever check code I add). What did I do wrong? I've read articles on the web including the doc on php official website but all comments, personal methods and differences from version to version, either with Postgres or PHP, make it very confusing and I eventually don't understand exactly show I should write my query and fetch_array. Thanks for any suggestions.
Here is my code from the original MySQL application:
// below is the "connexion.php" file
function connexion ()
{
$link=#mysql_connect ("localhost","username","pwd");
if ($link && mysql_select_db ("database"))
return ($link);
return (FALSE);
}
// below is the "index.php" file
require ("connexion.php");
connexion() or exit();
$reqcount = mysql_query ("SELECT * FROM people");
$result = mysql_num_rows($reqcount);
echo "Total : ".$result." people";
mysql_free_result ($reqcount);
mysql_query("set names 'utf8'");
$reqcat = mysql_query ("SELECT catname FROM categories ORDER BY catname");
while ($fieldcat = mysql_fetch_array($reqcat))
{
$name = $fieldcat[catname];
echo $name."<br>";
}
mysql_free_result ($reqcat);
mysql_close ();
And here is the PostgreSQL adaptation:
// connexion.php
function connexion ()
{
$link=pg_connect("host=localhost port=5432 dbname=database user=username password=pwd connect_timeout=5 options='--client_encoding=UTF8'");
return ($link);
}
// index.php
require ("connexion.php");
$reqcount = pg_query ($link,"SELECT * FROM people");
$result = pg_num_rows($reqcount);
echo "Total : ".$result." people";
pg_free_result ($reqcount);
$reqcat = pg_query ($link,"SELECT catname FROM categories ORDER BY catname");
while ($fieldcat = pg_fetch_array($reqcat))
{
$name = $fieldcat[catname];
echo $name."<br>";
}
pg_free_result ($reqcat);
pg_close ();
The php code for postgresql doesn't call connexion() so it never connects, unlike the mysql code.
You can try your query if it fails display error
$reqcount = pg_query ($link,"SELECT catname FROM people") or die(pg_last_error());
This way you can see your error.
errors
UPDATE:
Remove the # in your connection to see the error, and add or die(pg_last_error())
to see the error
What is causing my php code to freeze? I know it's cause of the while loop, but I have $max_threads--; at the end so it shouldn't do that.
<html>
<head>
<?php
$db = mysql_connect("host","name","pass") or die("Can't connect to host");
mysql_select_db("dbname",$db) or die("Can't connect to DB");
$sql_result = mysql_query("SELECT MAX(Thread) FROM test_posts", $db);
$rs = mysql_fetch_row($sql_result);
$max_threads = $rs[0];
$board = $_GET['board'];
?>
</head>
<body>
<?php
While($max_threads >= 0)
{
$sql_result = mysql_query("SELECT MIN(ID) FROM test_posts WHERE Thread=".$max_threads."", $db);
$rs = mysql_fetch_row($sql_result);
$sql_result = mysql_query("SELECT post FROM test_posts WHERE ID=".$rs[0]."", $db);
$post = mysql_fetch_row($sql_result);
$sql_result = mysql_query("SELECT name FROM test_posts WHERE ID=".$rs[0]."", $db);
$name = mysql_fetch_row($sql_result);
$sql_result = mysql_query("SELECT trip FROM test_posts WHERE ID=".$rs[0]."", $db);
$trip = mysql_fetch_row($sql_result);
if(!empty($post))
echo'<div class="postbox"><h4>'.$name[0].'['.$trip[0].']</h4><hr />' . $post[0] . '<br /><hr />[Reply]</div>';
$max_threads--;
}
?>
</body>
</html>
First, I'd suggest completely getting rid of the extraneous HTML bits. Then, build up your code slowly, line-by-line to see if you can find the offending line. So write a script that just connects to the database and see what happens.
If you find for example that this code...
<?php
$db = mysql_connect("host","name","pass") or die("Can't connect to host");
mysql_select_db("dbname",$db) or die("Can't connect to DB");
?>
...is causing the freeze on its own, then it could easily be a problem with the MySQL server.
However, if the browser itself is crashing, that sounds like an issue with your system rather than something that PHP or MySQL is doing...
Try this 1 SQL query instead of those 1 + (4 * n) queries:
SELECT MIN(ID), post, name, trip FROM test_posts GROUP BY Thread
Maybe a LIMIT 50 (or whatever max # of threads to return) at the end as well, that could be a lot of data.
You can just loop over the results of this query instead of $max_threads and all the extra db calls, via while ($row = mysql_fetch_row($sql_result)) { /* echo(...); */ }.
Not sure that's exactly the same as what you're trying to fetch without knowing more about the data (getting the root post of each thread in a forum?), but it should be pretty close.
(P.S.: if that's a threaded 2ch-style forum deal, I'm not sure that's an ideal db design. A parent-child adjacency list might be better than maintaining a number count for each thread. Just a guess though.)
I'm thinking it's because you're hitting the sql database 4 times per loop. Is there any way you can maybe access it all at once, and then parse the incoming data from there?
$dbsql = 'SELECT * FROM my_database';
$result = mysql_query($dbsql);
while($row = mysql_fetch_array($result)) {
// Parse information here, rather than
// accessing the database for individual variables...
}
Something like that.
Update:
Other than what I've already said (and you've dismissed) all I see are some here & there coding quirks:
This part didn't have a space between echo and the string. The 'hr' element didn't have a starting bracket.
echo '<div class="postbox"><h4>'.$name[0].'['.$trip[0].']</h4><hr>' . $post[0] . '<br /><hr />[Reply]</div>';
'while' Shouldn't be capitalized.
while($max_threads >= 0)
Again, clean code is a good place to start, but that's all I've got, personally. I just recently cleaned up my own site, which was crashing IE (and no other browser), simply because it had too many markup errors. Hope it helps.
Maybe you can scatter calls to this simple function in yer code:
function of($required)
{
$args = func_get_args();
var_dump($args);
ob_flush();
flush();
}
of(__LINE__, $max_threads);
You can also use something like this for your queries:
function mydb_query($query, $db = null)
{
$args = func_get_args();
$result = call_user_func_array('mysql_query', $args);
if (!$result) {
of(array(__FUNCTION__), mysql_error(), $sql);
//return something else?
}
return $result;
}
$result = mydb_query("SELECT post, name, trip FROM test_posts WHERE ID = (SELECT MIN(ID) FROM test_posts WHERE Thread={$max_threads})", $db);
You should use mysqli/PDO/framework with support for prepared statements.
Probably the script is exceeding the maximum server execution time threshold, try this on the top of your file to confirm this:
ini_set('max_execution_time', '180');
