The mysql query result can have 1 or 2 rows with results. How would I separate them?
$bio = mysql_query("SELECT *, FROM soc_meminfo
WHERE m_id = '".mysql_real_escape_string($en['id'])."'");
#
if (mysql_num_rows($bio) == 0) call404();
$line = mysql_fetch_assoc($bio);
foreach ($line as $key => $value) {
$en['b'.$key] = str_replace("\n",'<br/>',stripslashes($value));
}
Try this:
while ($row = mysql_fetch_assoc($bio)) { ... }
Also your sql should be SELECT * FROM soc_meminfo
try this
while ($row = mysql_fetch_assoc($bio)){
foreach ($row as $value){
echo $value;
}
echo '<br>';
}
I'm not sure I understand it, but try this.
$bio = mysql_query("SELECT *, FROM soc_meminfo
WHERE m_id = '".mysql_real_escape_string($en['id'])."'");
#
if (mysql_num_rows($bio) == 0) call404();
$line = mysql_fetch_assoc($bio);
foreach ($line as $key => $value) {
$en['b'.$key][] = str_replace("\n",'<br/>',stripslashes($value));
}

There are three "BC" in the result_category but I am only getting 1 result. This is for a personality quiz. Please Help. I also tried $query = "SELECT result FROM quiz_map where result_category = 'BC'"; but still, only 1 result is showing.
$result = mysqli_query($link, $query);
$cat_a = $cat_b = $cat_c = $cat_d = $cat_e = 0;
while($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {
$cat = $row['category'];
if ($cat == "A") {
$cat_a += 1;
} elseif ($cat == "B") {
$cat_b += 1;
} elseif ($cat == "C") {
$cat_c += 1;
} elseif ($cat == "D") {
$cat_d += 1;
} elseif ($cat == "E") {
$cat_e += 1;
}
}
$array = array('A' => $cat_a, 'B' => $cat_b, 'C' => $cat_c, 'D' => $cat_d, 'E' => $cat_e);
$str = '';
foreach ($array as $i => $value) {
if ($value >= 6) {
$str = $i;
break;
} elseif ($value >= 2) {
$str .= $i;
}
}
$var = sort($array);
$query = "SELECT result FROM quiz_map where result_category = '$str' LIMIT 1";
$result = mysqli_query($link, $query);
$row = mysqli_fetch_array($result);
echo $row[0];
?>
There's many things wrong with your code!
As pointed by #IsThisJavascript and #Cashbee:
You are executing a query with a LIMIT 1 statement, it will only return one record.
As pointed by myself:
Doing echo $row[0] will have the same result, if you are only echoing the first value of the array you can't expect to have multiples can you?
As pointed by #IsThisJavascript:
You need to loop the results array, like so:
while($row = mysqli_fetch_array($result)){
echo $row['result_category'];
}
Consider switching the query from a '=' to a '%like%' statement, to maximize results if you want to get the values that partionaly cointain the string.
Here is the content of my table:
How to count all names in different table cells to get a result like this?
Bob-7
Alex-3
Ivan-5
Nina-5
.........
With this code:
<?php
$q= mysqli_query($db, 'SELECT * FROM names');
while ($all = mysqli_fetch_array($q)) {
$k1= $all['Name1'];
$k2= $all['Name2'];
$k3= $all['Name3'];
$k4= $all['Name4'];
$k5= $all['Name5'];
$k6= $all['Name6'];
$arr[]= $k1;
$total_values = array_count_values($arr);
}
foreach ($total_values as $key => $value) {
echo $key .'-'. $value .'<br>';
}
My output result is:
Bob-3
Alex-1
Ivan-1
Nina-2
When I change my code to:
<?php
$q= mysqli_query($db, 'SELECT * FROM names');
while ($all = mysqli_fetch_array($q)) {
$k1= $all['Name1'];
$k2= $all['Name2'];
$k3= $all['Name3'];
$k4= $all['Name4'];
$k5= $all['Name5'];
$k6= $all['Name6'];
$arr=array($k1, $k2);
$total_values = array_count_values($arr);
foreach ($total_values as $key => $value) {
echo $key .'-'. $value .'<br>';
}
}
My output result is:
Bob-1
Alex-1
Ivan-1
Nina-1
Nina-1
Bob-1

What is wrong and what I have to do to add $k2, $k3....$k6 in the array $arr?
This will count the number of occurences for a single name:
$q= mysqli_query($db, 'SELECT * FROM names');
$arr = array();
// 1) loop through rows
while ($all = mysqli_fetch_array($q, MYSQLI_NUM)) {
// 2) loop through cells in a row
foreach($all as $val) {
// 3) 'roll out' the values into a one-dimensional array
if(empty($val)) { continue; } // if you don't want to count empty cells
$arr[] = $val;
}
}
// 4) count the number of occurences
$names_qty = array_count_values($arr);
// optional loop that shows the results
foreach($names_qty as $name=>$qty) {
echo $name.'-'.$qty.'<br />';
}
The benefit of this solution is that you call the counting function only once and not in every iteration.
You have to accumulate data in a loop and print it after all data is processed.
$total = array();
$result = mysqli_query($db, 'SELECT * FROM names', MYSQLI_USE_RESULT);
while (mysqli_fetch_assoc($result) as $row) {
foreach ($row as $col => $value)
total[$col]++;
}
}
print_r($total);
This code is tested and should do the trick.
<?php
$arr = array();
$q = mysqli_query($db, 'SELECT * FROM names');
while ($all = mysqli_fetch_assoc($q)) {
foreach($all as $val) {
if(empty($val)) {
continue;
}
// saves all names with the name as key
$arr[$val][] = $val;
}
}
// Output
foreach($arr as $k => $v) {
// count how many times the name was pushed into the array
echo $k.' - '. count($v);
}
I've got a very minor problem but it's one I'd like to work out, so I'm looking for suggestions.
I'm using the following PHP code to echo the data from an array.
$array = array();
$rsa = $wpdb->get_results("SELECT * from wp_letter ORDER BY l_name ASC");
foreach($rsa as $rrr)
{
array_push($array,$rrr->l_name);
}
$temp = 0;
foreach($array as $as)
{
$temp = 0;
$query = $wpdb->get_results("SELECT * FROM wp_term_taxonomy AS tx, wp_terms AS trm WHERE taxonomy = 'category' AND trm.term_id = tx.term_id AND name like '".$as."_%' ORDER BY name ASC");
foreach($query as $row1)
{
if($temp == 0)
{
echo '<h4>'. $as.'</h4>';
$temp = 1;
}
?>
<a class="anchor" href="<?php echo esc_url(get_category_link($row1->term_id)); ?>"><?php echo $row1->name;?></a><br/>
<?php }
} ?>
Just add the LIMIT 3 into your Query, e.g.
SELECT * from wp_letter LIMIT 3 ORDER BY l_name ASC;
You could either use some crap like (for example):
$query = [1,2,3,4,5,6,7,8,9,10,11,12,13,14];
$results = ['1col' => [], '2col' => [], '3col' => []];
foreach($query as $key => $result) {
if (($key+1) % 2 === 0 && !(($key + 1) % 3 === 0)) {
$results['2col'][] = $result;
} elseif (($key+1) % 3 === 0) {
$results['3col'][] = $result;
} else {
$results['1col'][] = $result;
}
}
OR just smth like this:
$results = array_chunk($query, ceil(count($query)/3));

I want to store result of a query as associative array. Below is my code that generates the query result below.
<?php
$include('config.php') //mysql connection file
$result = mysql_query("SELECT daystime.*, Sprinkler_ID FROM daystime, scheduler WHERE daystime.id = scheduler.DaysTime_ID ORDER BY daystime.id, Sprinkler_ID") or trigger_error(mysql_error());
$data_array = array();
while($rs = mysql_fetch_assoc($result))
{
$key=$rs['id'];
$value=$rs['Sprinkler_ID'];
$data_array[$key] = [$value];
}
foreach ($data_array as $key => $value)
{
echo $key.'=>'.$value.'<br />';
}
?>
This gives me output as
19=>Array
20=>Array
21=>Array
27=>Array
29=>Array
But I should get
19 -> [4,5],
20 -> [5],
21=>[4,6],
// and so on
$value is an array, you can't use echo on arrays
Don't loop just do a var_dump()
$data_array = array();
while($rs = mysql_fetch_assoc($result)){
$data_array[$rs['id']][]=$rs['Sprinkler_ID'];
}
var_dump($data_array);//or print_r($data_array);
<?php
$include('config.php') //mysql connection file
$result = mysql_query("SELECT daystime.*, Sprinkler_ID FROM daystime, scheduler WHERE daystime.id = scheduler.DaysTime_ID ORDER BY daystime.id, Sprinkler_ID") or trigger_error(mysql_error());
$data_array = array();
while($rs = mysql_fetch_assoc($result))
{
$key=$rs['id'];
$value=$rs['Sprinkler_ID'];
$data_array[$key] = [$value];
}
$out = '';
$count = count($data_array);
$iter = 0;
foreach ($data_array as $key => $value)
{
$out.= $key.'=>[';
foreach ($value as $val) {
$out.=$val.',';
}
$out = rtrim($out, ",");
$out.= ']';
if ($iter < ($count-1)) {
$out.=',<br />';
}
$iter++;
}
echo $out;
You need an inner foreach loop to handle printing the array in $value as this is a multi dimensional array. The preceding is an example of how it could look to produce the exact output you requested. If you are looking for a dump of the values, then please use the var_dump solution provided by #meda.
There are two issues in your code. The first is that $value is an array, the second is that this array only contains one item.
Try this:
$data_array = array();
while($rs = mysql_fetch_assoc($result))
{
$key=$rs['id'];
$value=$rs['Sprinkler_ID'];
$data_array[$key][] = $value;
}
foreach ($data_array as $key => $values)
{
echo $key.'=> [';
foreach($values as $value)
echo $value . ',';
echo ']<br />';
}
I have a simple database connection:
$rowdata = mysql_query("SELECT * FROM table_names");
while($row = mysql_fetch_array($rowdata)) {
echo "".$row['name'].",";
}
I would like it to print out:
Adam, Sophia, Tom, Brian
instead of:
Adam, Sophia, Tom, Brian,
How do I exclude the last comma in the best way?
$rowdata = mysql_query("SELECT name FROM table_names");
$names = array();
while($row = mysql_fetch_array($rowdata)) {
$names[] = $row['name'];
}
echo implode(', ', $names);
Instead of echoing it straight out, put it into a variable (named $values perhaps) then do:
$values = rtrim($values,",");
Print the comma before each entry and omit the first one:
$first = TRUE;
while(($row = mysql_fetch_array($rowdata)) !== FALSE) {
if(!$first) echo ',';
echo htmlspecialchars($row['name']);
$first = FALSE;
}
Another way would be to use extract echoing the first line from the loop, that way the if statement does not have to be evaluated each iteration (premature optimization ftw!):
if(($row = mysql_fetch_array($rowdata)) !== FALSE)
echo htmlspecialchars($row['name']);
while(($row = mysql_fetch_array($rowdata)) !== FALSE) {
echo ',', htmlspecialchars($row['name']);
}
And finally you can do it in mysql:
select group_concat(name) from table_names
In full this would become:
$rowdata = mysql_query("SELECT group_concat(name) as names FROM table_names");
while($row = mysql_fetch_array($rowdata)) {
echo $row['names'];
}
$rowdata = mysql_query("SELECT * FROM table_names");
$names = array();
while($row = mysql_fetch_array($rowdata)) {
$names[] = $row['name'];
}
echo implode( $names, ',' );
By the way, if you're only using the 'name' column, it's better to do SELECT name FROM ..
Make it ..
$names = array();
while ( $row = mysql_fetch_array( $rowdata ) ) {
$names[] = $row['name'];
}
$names = implode(', ', $names);
echo $names;
