I have a function in PHP that give me some values from DB
$select = mysql_query("SELECT * FROM sfide WHERE accepted = 0");
if($select){
if(mysql_fetch_row($select) != 0){
$sep = "~";
$return = "";
$i = 0;
while($row = mysql_fetch_array($select)){
if($i > 0){
$return = $return.",";
};
$return = $return.$row['id'].$sep.$row['from_'];
$i += 1;
}
return $return;
}else{
return "NO";
}
}else{
return "E, 000, SELECT, ".mysql_error();
}
The problem is that if I do like in the code above it returns me nothing, instead, if I duplicate the select variable it works:
$select = mysql_query("SELECT * FROM sfide WHERE accepted = 0");
$num_select = mysql_query("SELECT * FROM sfide WHERE accepted = 0");
if($select){
if(mysql_fetch_row($num_select) != 0){
$sep = "~";
$return = "";
$i = 0;
while($row = mysql_fetch_array($select)){
if($i > 0){
$return = $return.",";
};
$return = $return.$row['id'].$sep.$row['from_'];
$i += 1;
}
return $return;
}else{
return "NO";
}
}else{
return "E, 000, SELECT, ".mysql_error();
}
Why ?
Instead of
mysql_fetch_row($select) != 0
use
mysql_num_rows($select) != 0
that will return an int for you to compare.

When I view the record from the database, the result is displayed as null.
This is what I tried so far:
<?php
include("db.php");
$fetchqry = "SELECT mid, planid, paid_date, expire_date FROM payment";
$result = mysqli_query($conn, $fetchqry);
$num = mysqli_num_rows($result);
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
$mid = $row['mid'];
$planid = $row['planid'];
$date1 = $row['expire_date'];
if (strtotime(date("Y/m/d")) < strtotime($date1))
{
$status = "Active";
}
else
{
$status = "Expired";
}
}
echo json_encode($row);
?>
Add the values you read from the DB to an array, then encode that.
$output = [];
$today = strtotime(date("Y/m/d"));
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
$mid = $row['mid'];
$planid = $row['planid'];
$date1 = $row['expire_date'];
if($today < strtotime($date1))
{
$status = "Active";
}
else
{
$status = "Expired";
}
$output[] = ['mid' => $mid, 'planid' => $planid, 'status' => $status];
}
echo json_encode($output);
I submitted these two files:
sample_annotation.txt
sample_synteny.txt
I got on the next page the following error:

I created a docker-compose.yml and the can be run in the following way:
git clone https://github.com/mictadlo/mGSV-docker.git
docker-compose up --build
The service can be accessed via localhost and PhpMyAdmin can be accessed via localhost:8183
What did I miss?
Thank you in advance
Try to run independently both query in your Mysql phpmyadmin
select distinct org1,org2 from '.304342020180200000016.'_synteny
select distinct org1,org2 from '.304342020180200000016.'_synteny
As i see your query seems to be correct since union requires the same numbers of columns and same data type.
And why is your table name in the union query is both the same.
it seem like i get stocked in loop ,i didn't know why this is my code-
$db = new mysqli("localhost", "root", "", "gdwal");
$sub = mysqli_query($db, "SELECT *,priority FROM subjects,teacher WHERE teach =techID ");
$stack = array();
$num = mysqli_query($db, "SELECT count(capacity)'h' FROM rooms ");
$table[][] = array();
$x = mysqli_fetch_array($num);
$table[0][0] = 0;
if ($db) {
echo 'connected';

It seems your "back" function calls "choose" function.
And your "choose" function calls your "back" function.
The loop is complete.
I have marked it with //////// to make it easy to find.
Edit I see now that there is several places in back you call choose. I have only marked one.
It's not to hard to find it with search function of any developer app.

You need to make a unique row inside database. You can't do it with PHP.
Add all columns to a single UNIQUE index, the you can't insert duplicate rows in that table.
I am a completely newbie in programming php I would like to make this code below return many arrays(to flash as3), however I only receive one array.Can anyone please pinpoint what is my mistake here? thanks.
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
echo "returnStr=$data_array";
exit();
}
When you write your exit insight your loop you stop executing your program and you get only one record. You should set the echo and exit after your while loop.
$data_array = "";
$i = 0;
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql)) {
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1) {
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
} else {
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
Those two last line of your should be outside of your loop:
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
If you would name the columns that you want in the SELECT then it's much simpler. Make sure to use MYSQLI_ASSOC in the fetch:
$sql = mysqli_query($conn, "SELECT Username, Fb_id, Access_token, Fb_sig, Char_id FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql, MYSQLI_ASSOC))
{
$data_array[] = implode('|', $row);
}
echo "returnStr=" . implode('(||)', $data_array);
exit();
