i try to list a overview for a gallary by using 'list' and 'foreach' , but i always get just one (the oldest) result from my database.
i use this
while($row = mysql_fetch_array($result)){
$galpath1 = "galerie/";
$gal_title = $row['gal_title'];
$gal_path= $galpath1.$row['uploads'];
$nickname = $row['nickname'];
$added = $row['format_date'];
$galshow = [
[$gal_path, $gal_title, $added],
];
}
if(!empty($gal_path))
{
var_dump($galshow);
foreach ($galshow as list($gal_pathes, $gal_titles, $addeds)) {
List of galerys
}
how can i bring it to work so that i can list all gallerys that matches the select in my database?
Thank you so much cdhowie
you saved my day. that was exactly what i did wrong.
so thanks for the quick response. :)
Every iteration of the while loop you overwrite the value in $galshow with a new array containing one element. As a result, this array will only ever contain one element, and it will be the last row fetched from the database.
Instead, create a new array outside of the loop and append to it inside the loop:
$galshow = array();
while($row = mysql_fetch_array($result)){
$galpath1 = "galerie/";
$gal_title = $row['gal_title'];
$gal_path = $galpath1.$row['uploads'];
$nickname = $row['nickname'];
$added = $row['format_date'];
// This syntax will append a new array to the end of the $galshow array.
$galshow[] = [$gal_path, $gal_title, $added];
}

I can't seem to find a way to save all rows from odbc_exec to an array. I found php_fetch_array, but that only fetches one row at a time, requiring me to iterate through all rows to put it into an array. Is there a more concise way to do this?
Tried
`
$myArray = array();
while (odbc_fetch_row($result)) {
$myArray[odbc_result($result,1)] = odbc_result($result,2);
}`
and also
`
$myArray = array();
while ($myRow = odbc_fetch_row($result)) {
$myArray[$myRow['id']] = $myRow['name'];
}`
but $myArray is still empty.
I'm trying to add an element to array, but I get a weird output. The code is the following:
$getalltokens = $db->query("SELECT * FROM Tables WHERE available = '$comp'");
while ($row = $getalltokens->fetch(PDO::FETCH_ASSOC))
{
$fid = $row['FID'];
$tok = $row['token'];
$sql = $db->query("SELECT Firstname,Lastname FROM Users WHERE Token = '$tok'");
$rez = $sql->fetch(PDO::FETCH_ASSOC);
$names[] = $rez;
$fidzy = array(
'FID' => $fid
);
array_push($names, $fidzy);
}
$getalltokens = $db->query("SELECT FID FROM Tables WHERE available = '$comp'");
$tokenz = $getalltokens->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($names);
And the output I get is:
[{"Firstname":"Test","Lastname":"Test"},{"FID":"5"},
{"Firstname":"Test2","Lastname":"Test2"},{"FID":"4"}]
While what I need is the FID to be inside the $names array, so it would be more like:
[{"Firstname":"Test","Lastname":"Test","FID":"5"}]
$rez['FID'] = $fid; /* Added */
$names[] = $rez;
/* $fidzy and array_push removed */
You can use instead of array_push() like
$arrayname[indexname] = $value;
if you use array_push()
<?php
$array[] = $var;
?>
Note: If you use `array_push()` to add one element to the array it's
better to use$array[] = because in that way there is no overhead of
calling a function.
Note: `array_push()` will raise a warning if the first argument is not an array. This differs from the `$var[]` behavior where a new array
is created.
Reference Array push
The solution to the specific problem at hand is selecting all the necessary data in a single query, removing the need to add elements to any array. This is done in the following fashion:
$sql = $db->query("SELECT
Users.Firstname,Users.Lastname,Tables.FID
FROM Users,Tables
WHERE Users.Token = Tables.token");
$rez = $sql->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($rez);
i have a mysql table the contains an index id, a data entry and 10 other columns called peso1, peso2, peso3...peso10. im trying to get the last 7 peso1 values for a specific id.
like:
$sql = mysql_query("SELECT * FROM table WHERE id='$id_a' ORDER BY data DESC LIMIT 0, 7");
when i try to fetch those values with mysql_fetch_array, i get all values together.
example:
while($line = mysql_fetch_array($sql)) {
echo $line['peso1'];
}
i get all peso1 values from all 7 days together. How can i get it separated?
They will appear all together because you are not separating them as you loop through them.
for example, insert a line break and you will see them on separate lines
while($line = mysql_fetch_array($sql)) {
echo $line['peso1'] ."<br />";
}
You could key it as an array like so
$myArray = array();
$i = 1;
while($line = mysql_fetch_array($sql)) {
$myArray['day'.$i] = $line['peso1'];
$i++;
}
Example use
$myArray['day1'] // returns day one value
$myArray['day2'] // returns day two value
It's not clear what you mean by "separated" so I'm going to assume you want the values as an array. Simply push each row field that you want within your while loop onto an array like this:
$arr = array();
while($line = mysql_fetch_array($sql)) {
$arr[]=$line['peso1'];
}
print_r($arr);//will show your peso1 values as individual array elements
I am basically trying to fetch results from a SQL database and load that into a multidimensional array so i can use them later on in the page.
while($row = mysqli_fetch_array($result))
{
$send = array
(
array($row['Name'],$row['Email'],$row['Mobile'])
);
$count = $count + 1;
}
That is what i am using to get the results which if i print within the while loop it will echo all the results. However when putting it into the array it loads each result into the array as the first result. My initial plan was to use a counting variable to set where in the array the result was set to with this adding by one each time. I am not certain how to specify where to add the result i thought something along the lines of
$send = array[$count]
(
array.....
so i could then refer to the results as 0 to count length but i am not sure how to make this work. Or ,which i presume, if there is a much easier and better way of going about it. I am also not sure if this is necessary as surely the results seem to be in an array when gathered from the SQL database but i am unsure if this array is populated with each while loop or stored and can be accessed at any point
If any one can give me an example of something similar or point me at some documentation much appreciated
Try this:
$count = 0;
while ($row = mysqli_fetch_array($result)) {
$send[$count] = array($row['Name'], $row['Email'], $row['Mobile']);
$count++;
}
I have a better way for you. You could also use the id for your index, if you have one:
while ($row = mysqli_fetch_array($result)) {
$send[$row['id']] = array(
"Name" => $row['Name'],
"Email" => $row['Email'],
"Mobile" => $row['Mobile']
);
}
You can use:
$count = 0;
while($row = mysqli_fetch_array($result))
{
$send[$count] = $row;
$count ++;
}
Also you might want to use the table id as an array index, so you can access the records by ID later. In that case you can do:
while($row = mysqli_fetch_array($result))
{
$send[$row['id']] = $row;
}
You're declaring your array inside your loop. So it will reset it every time.
$send = array();
while($row = mysqli_fetch_array($result))
{
$send[] = array($row['Name'],$row['Email'],$row['Mobile']);
}
What am I trying to do is collect data from a while loop, store it into a variable. Then later in my code I see if some variable is equal to one of the values in the array and then to echo out the two other column values I got from the while loop but equal to the row that the value came from. I have tried a bunch different things and am so close but cant get it exactly.
while($row = mysql_fetch_assoc($query)){
$team[] .= "{$row['team']}";
$winslosses .= "({$row['wins']} - {$row['losses']})";
}
this returns something like
$team = (bears, badgers, wildcats)
$winslosses = ((42-24), (55-23), (32-21))
Then later in my code I want to see if its equal to a value in the array then echo $winslosses.
if(in_array(bears, $team) ) {echo '$winslosses';}
This shows all the wins and losses from each team. I want it only show me the record of the bears.
Any help would be great.
You can use array_search() to get the index of an item in an array. You can then use that index when querying $winlosses:
$team = array(bears, badgers, wildcats);
$winslosses = array("(42-24)", "(55-23)", "(32-21)");
$key=array_search(bears, $team);
echo $winslosses[$key]
results in:
(42-24)
Your best bet would be to store them in an associative array.
while($row = mysql_fetch_assoc($query)){
$winslosses[$row['team']] = "({$row['wins']} - {$row['losses']})";
}
Hope this helps
Your main problem is that you currently have $winslosses as a string, not an array, so you can't easily pull out the win/loss record for just one team.
There are several ways you could do this. The one that seems easiest to me would be to put it together as one array up front.
Something like...
while($row = mysql_fetch_assoc($query)){
$teams[$row['team']] = "({$row['wins']} - {$row['losses']})";
}
Then later on...
if(array_key_exists("bears",$teams)) {
echo $teams["bears"];
}
Or even better, store the wins/losses as a sub-array, so you have structured data that you can format however you want later on.
while($row = mysql_fetch_assoc($query)){
$teams[$row['team']] = array("wins" => $row['wins'], "losses" => $row['losses']);
}
echo $teams['bears']['wins']; // for example
Use associative array:
while($row = mysql_fetch_assoc($query)){
$team[] = {$row['team']};
$winslosses[$row['team']] = "{$row['wins']} - {$row['losses']}";
}
Then retrieve it like this:
if(in_array(bears, $team) ) {
echo $winslosses['bears'];
}
As a matter of fact, if you do not need the names of the teams in a separate array, you can just use one associative array and then retrieve it.
if (array_key_exists('bears', $winslosses)) {
echo $winslosses['bears'];
}
