So I get the following error.
[02-Nov-2015 16:29:48 America/Los_Angeles] PHP Warning:
number_format() expects parameter 1 to be double, string given in
C:\inetpub\wwwroot\handpaytest\index.php on line 17
This the code that its complaining about.
echo "<td>Past Week: $" . number_format(htmlspecialchars($cell)) . "</td>";
In context
<div id='Title'></div>
<div id='week'>
<?php
echo "<center><table>\n\n";
$f = fopen("week.csv", "r");
while (($line = fgetcsv($f)) !== false) {
echo "<tr>";
foreach ($line as $cell) {
echo "<td>Past Week: $" . number_format(htmlspecialchars($cell)) . "</td>";
}
echo "</tr>\n";
}
fclose($f);
echo "\n</center></table>";
?>
</div>
What htmlspecialchars does is Convert special characters to HTML entities
So, you need to Type caste $cell as (float)$cell before passing it to
number_format
number_format((float)$cell)
As we don't know what $cell contains, You can try to force its type to be float.
echo "<td>Past Week: $" . number_format((float)$cell)) . "</td>";

i have a variable Q,
i want to print "cat" (or whatever) Q times in HTML table rows, only each row of the HTML table can contain maximum of 5 cats.
like if Q <= 5 then i want to print a single <tr>.
& if Q = 10;
then i want to print 2 rows each containing 5 cats.
can someone help me here?
I'm using php as the programming language and HTML.
thanks in advance.
You can also make use of array_chunk to decide the chunk(no. of times) for each row and repeat a string using str_repeat the chunk size times to achieve your goal.
<?php
$times = 12;
$limit_for_each_row = 5;
$string = "Cat";
echo "<table>";
foreach(array_chunk(range(1,$times),$limit_for_each_row) as $chunk){
echo "<tr>" . str_repeat("<td>$string</td>",count($chunk)) . "</tr>";
}
echo "</table>";

May following code will help you to achieve requested output:
<?php
$print_label = "meow";
$q = 15;
$steps = 5;
echo "<table>";
for($i=1;$i<=ceil($q/$steps);$i++) :
echo "<tr>";
for($j=1;$j<=$steps;$j++) :
echo "<td>".$print_label."</td>";
endfor;
echo "</tr>";
endfor;
echo "</table>";
One way to solve this problem is by using array_fill to make an array of $q copies of the word; array_chunk to split that into the maximum number of words per row; and implode to put all the words in each chunk together into a row:
$word = "cat";
$q = 13;
$row_max = 5;
$words = array_fill(0, $q, $word);
$chunks = array_chunk($words, $row_max);
foreach ($chunks as $chunk) {
echo '<tr><td>' . implode('</td><td>', $chunk) . '</td></tr>' . "\n";
}
Output:
<tr><td>cat</td><td>cat</td><td>cat</td><td>cat</td><td>cat</td></tr>
<tr><td>cat</td><td>cat</td><td>cat</td><td>cat</td><td>cat</td></tr>
<tr><td>cat</td><td>cat</td><td>cat</td></tr>

I am trying to divide CSV into Two String LHS_String and RHS_String. For Example, I have the below CSV -
customer^id,record^id
customer^fname,record^first_name
cusomer^gender,record^gender
The Output should be like -
LHS_String : customer^id
RHS_String : record^id
Short answer, read over http://php.net/manual/en/function.explode.php
Example:
<?php
$data = "customer^id,record^id\r\n";
$data .= "customer^fname,record^first_name\r\n";
$data .= "cusomer^gender,record^gender\r\n";
$p1 = explode("\r\n", $data);
$p2 = array();
foreach($p1 as $key => $line){
$p2[$key] = explode(",", $line);
}
echo "LHS_String : " . $p2[0][0] . "\r\n";
echo "RHS_String : " . $p2[0][1] . "\r\n";
?>

Can anybody tell me why I can't get this to work?
I am simply trying to sort my arrays from highest to lowest.
$stuff[] = "100";
$stuff[] = "104";
$stuff[] = "102";
$stuff[] = "103";
$stuff[] = "101";
$stuff[] = "99";
echo "Largest: " . max($stuff) . " <br> \n";
arsort($stuff);
echo "0 : " . $stuff[0] . " <br> \n";
echo "1 : " . $stuff[1] . " <br> \n";
echo "2 : " . $stuff[2] . " <br> \n";
echo "3 : " . $stuff[3] . " <br> \n";
echo "4 : " . $stuff[4] . " <br> \n";
echo "5 : " . $stuff[5] . " <br> \n";
arsort() is sorting your array, but it also conserve the keys of each value. Witch mean the key 0 will still answer with 100, and not the first element !
With a foreach, you would see them in correct order.
foreach ($stuff as $value) {
echo $value . "<br>\n";
}
OR
You can also use rsort() that will not be associative, which mean the keys won't have the same values after it.

I have the following post string:
Name=John&Age=33&Question1=What's+your+gender%3F&Answer1=Male&Question2=What's
+your+education%3F&Answer2=Graduate
I'm going to have randomly generated amount of questions each time so I won't be able to know number of passed variables. Thus, I am searching for a solution something like:
foreach($postItem as $varr) {
echo $varr["name"].": ".$varr["value"]."<br />";
}
Post them as answer[1], answer[2] etc instead of answer1, answer2, and PHP will turn them into an array for you.
//parse query string to an array ($output)
parse_str($postString, $output);
echo $output['Name'] . ': ' . $output['Age'] . '<br />';
//process questions
$i = 1;
while (array_key_exists('Question' . $i, $output)) {
echo $output['Question' . $i] . ': ' . $output['Answer' . $i] . '<br />';
$i++;
}

I have using this code between echo "";
<?php
for ($i=0; $i<$tot; $i++)
{
$rt = date ( "d-m-Y", $y[$i] ) ;
}
?>
Please specify how to implement this code between echo "";
<?php
$output = 'for ($i=0; $i<$tot; $i++){ ';
$output .= '$rt = date ( \'d-m-Y\', $y[$i] );';
$output .= '}';
echo $output;
?>
For readability I separated it into 4 lines, but you can see how it could easily be refactored into one echo statement.
The key idea here is that by declaring strings with ' instead of ", php will not interpret the $ signs as variables. Additionally, in order to include single quotes within the string itself, a backslash escape character is required as in \'d-m-Y\'
