I am using 3 php arrays to create a table, these three arrays are used to generate table headers.
$array1 = array('A','B');
$array2 = array('S','C');
$array3 = array('A1','B1','C1','D1');
Generate a table with these array values are headers.
I want to create a table like in image using these three array.
The following code is used to dynamically generate the table that you have shown. You can change the values of $array1, $array2 or $array3 respectively and table is generate dynamically.
<?php
$array1 = array('A','B','C');
$array2 = array('S','C','M');
$array3 = array('A1','B1','C1','D1','E1','F1');
/* Get the length of all arrays */
$lengthArray1 = count($array1);
$lengthArray2 = count($array2);
$lengthArray3 = count($array3);
?>
<table border="1" width="50%">
<thead>
<!-- Print the header -->
<tr>
<!-- For first empty space -->
<td></td>
<?php
/* Based on the length of the array display the headers */
for($i = 0; $i < $lengthArray1; $i++){ ?>
<!-- Align center and add the colspan wrt to $array length -->
<td colspan="<?php echo $lengthArray2; ?>" align="center">
<?php echo $array1[$i]; ?>
</td>
<?php
} ?>
</tr>
<tr>
<!-- For first empty space -->
<td></td>
<?php
/* Loop through all the $array1 so that that many $array2 values will be assigned to $array1 header */
for($i = 0; $i < $lengthArray1; $i++){
for($j = 0; $j < $lengthArray2; $j++){
?>
<td align="center">
<?php echo $array2[$j]; ?>
</td>
<?php
}
} ?>
</tr>
</thead>
<tbody>
<!-- Loop through $array3 -->
<?php
for($i = 0; $i < $lengthArray3; $i++){ ?>
<tr>
<!-- Print $array3 value in first td -->
<td><?php echo $array3[$i]; ?></td>
<?php
/* To get the remaining td's I have multiplied $array1 X $array2 */
for($j = 0; $j < ($lengthArray1 * $lengthArray2); $j++){
?>
<td></td>
<?php
}
?>
</tr>
<?php
} ?>
</tbody>
</table>

I want to save my input values into a 2D array.
<table>
<?php
$kriteria = array('IP', 'SE', 'PE', 'BE');
?>
<thead>
<tr>
<th>Kriteria</th>
<?php
foreach ($kriteria as $val) {
echo '<th>' . $val . '</th>';
}
?>
</tr>
</thead>
<tbody>
<?php $n = count($kriteria); ?>
<?php for ($i = 0; $i < $n; $i++): ?>
<tr>
<th>
<?= $kriteria[$i] ?>
</th>
<?php for ($j = 0; $j < $n; $j++): ?>
<td><input type="text" class="form-control" id="<?= $kriteria[$j] . $kriteria[$i] ?>" name="<?= $j. $i ?>" value=""></td>
<?php endfor; ?>
</tr>
<?php endfor; ?>
</tbody>
</table>
I tried with the POST method but it didn't work.
I want to use the value from the input for counting in another page.
this the result

I need to fill a 10x10 html table using php code with a random number from 1-10 rand(1,10), then depending on the result paint the cell red if <5 or green if >5. i manually created 10 rows with 10 td each and inside I put echo(rand(1,10)) for each one of them but my syntax is wrong and it looks gross
<table>
<tbody>
<?php for ($i = 0; $i < 10; $i++) : ?>
<tr>
<?php for ($k = 0; $k < 10; $k++) : ?>
<?php $num = rand(1, 10); ?>
<td style="color: <?= $num < 5 ? 'red' : 'green'; ?>"><?= $num; ?></td>
<?php endfor; ?>
</tr>
<?php endfor; ?>
</tbody>
</table>
I don't even have an idea of where to start for this. I need to display 100 numbers in a table and would like to use a while loop to do so. Is there a "shortcut" to doing this?
For a table you need some tags table, tr and td. The tr and td are in while loop and the value $i will print inside the td.
<table>
<?php
$i = 1;
while($i != 101){?>
<tr><td><?php echo $i++;?></td></tr>
<?php }?>
</table>
You can use while, for, foreach for your convenience, like below code
<table>
<thead>
<tr>
<th class="header">Number</th>
</tr>
</thead>
<tbody>
<?php
$i = 1;
while($i != 101){
?>
<tr>
<td><?php echo $i; ?></td>
</tr>
<?php
$i++;
} ?>
</tbody>
</table>
You can dipslay 100 numbers simply in tbale like this:
<?php
// Using For loop
echo "<table>";
for ($i = 1;$i <= 100; $i++) { // use for loop
echo "<tr><td>".$i."</td></tr>";
}
echo "</table>";
// OR
// Using while loop
$i = 1;
echo "<table>";
while($i <= 100) {
echo "<tr><td>".$i."</td></tr>";
$i++;
}
echo "</table>";
?>
You can use a while loop:
while ($i <= 100) {
echo "<td><tr>" . $i++ . "</tr></td>";
}
I'm creating a series of content blocks. (4 in total).
It's stupid to create all for of them if you can let php create them for you.
So I created the first one and wrote a for loop that adds the content as long as it haven't a max number of 4.
Here it is:
<table>
<tr>
<?php
$counter =0;
for ($i=0; $i <= 3; $i++){
$counter++;
?>
<td>some content to repeat with id='$id++' and '$id++'</td>
<?php
if ($counter == 2){
echo '</tr><tr>';
$counter=0;
}
}
?>
</tr>
</table>
What this does is repeat the <td> two times and then end the rule and start a new one. Do this until you reach an amount of 4 (3 because 1=0)
The problem I have is that some of the content contains id's
The id's should also number up but only if the complete loop is repeated.
So $i++ should both have the same value if the loop runs once
So that would mean that if there are two id's in the first run they should both have the id1 and the next repeat should have id2
I have no idea how to do this.
The output should be:
<table>
<tr>
<td>
This content has id 1
And this content has id 1 to
<td>
<td>
This content has id 2
And this content has id 2 to
<td>
</tr>
<tr>
<td>
This content has id 3
And this content has id 3 to
<td>
<td>
This content has id 4
And this content has id 4 to
<td>
</tr>
</table>
M.
How about this
<table>
<?php
$id = 1
for ($i=0; $i < 2; $i++){
echo '<tr>';
for ($j=0; $j < 2; $j++){
echo 'This content has id $id';
echo' And this content has id $id too';
}
$id += 1;
echo '</tr>';
}
}
?>
</table>
Update: added an id counter.
Is this what you mean? You don't need $counter as you have $i keeping count for you.
<table>
<tr>
<?php for ($i=0; $i <= 3; $i++){ ?>
<td<?php
if ($i < 2) echo ' id="1"';
else echo ' id="2"';
?>>some content to repeat</td>
<?php if ($i == 1){ echo '</tr><tr>'; } ?>
<?php } ?>
</tr>
</table>
I have retrieved some values from database. In my view file I have the following:
$row['fee_amount'];
Now, I want to sum up all the values inside $row['fee_amount']; and then show it.
I know I could sum up when querying the database, but I am interested to learn how to add using PHP .
Would you please kindly teach me how to do it?
EDIT
<?php if(count($records) > 0) { ?>
<table id="table1" class="gtable sortable">
<thead>
<tr>
<th>S.N</th>
<th>Fee Type</th>
<th>Fee Amount</th>
</tr>
</thead>
<tbody>
<?php $i = 0; foreach ($records as $row){ $i++; ?>
<tr>
<td><?php echo $i; ?>.</td>
<td><?php echo $row['fee_type'];?></td>
<td><?php echo $row['fee_amount'];?></td>
</tr>
<?php } ?>
</tbody>
<tr>
<td></td>
<td>Total</td>
<td>
I WANT TO DISPLAY THE SUMMATION RESULT HERE ADDING UP VALUES INSIDE THIS>>> <? $row['fee_amount']; ?>
</td>
</tr>
</table>
<?php } ?>
In your view file, with your foreach loop, add a $sum variable next to your $i counter and add the amount per each iteration (similar to like you increase $i):
<?php
$i = 0;
$sum = 0;
foreach ($records as $row)
{
$i++;
$sum += $row['fee_amount']; ?>
(I put this over multiple lines to make it more readable).
After the foreach has finished, $sum contains the total amount:
<td>Total: <?php echo $sum; ?></td>
That simple it is. You only need a new variable ($sum) and do the calculation.
Use a loop
$sum = 0;
while($row...){
$sum += $row['fee_amount']
}
echo $sum;
You could use;
$someValue = 0;
foreach($row["fee_amount"] as $value) {
$someValue = $someValue + $value;
}
using this php function, if $row['fee_amount'] is an array ^_^
for example:
$a = array(2, 4, 6, 8);
array_sum($a)
