I created a code that converts characters to binary and make table cells black/white corresponding to the ones and zeros. This is my code:
$str_splt = str_split($text);
echo "<table>";
for ($a=0;$a < count($str_splt);$a++) {
$bits = array(128,64,32,16,8,4,2,1);
$store = array(0,0,0,0,0,0,0,0);
$inp = ord($str_splt[$a]);
for ($x=0;$x < count($bits);$x++) {
if ($bits[$x] <= $inp) {
$inp = $inp - $bits[$x];
$store[$x] = 1;
} else {
$store[$x] = 0;
}
};
$store_rvs = array_reverse($store);
echo "<tr>";
for ($b=0;$b < count($store_rvs);$b++) {
if ($store_rvs[$b] == '1') {
echo "<td id=\"blk\"></td>";
}
else {
echo "<td></td>";
}
}
echo "</tr>";
}
echo "</table>";
Its output looks like this ($text = "ABCDEFGH"):
As you can see it's 8x8 table. I want to add the next set of bytes to the side of that table like this:
Each 8x8 table is a group. The two images above is group 1 and group 2:
I want to display the tables like this but I can't find the solution.
I did it in this way. Ignore my css if you are fine with yours. I replaced the id tag with class because each id should be defined once only.
echo "<html><head>";
echo "<style type='text/css'>";
echo " table, td { padding:0px; margin:0px; }";
echo " td.cell { width:15px; height:15px; }";
echo " td.blk { background-color:black; }";
echo " td.wht { background-color:yellow; }";
echo "</style>";
echo "</head><body>";
$text = "ABCDEFGH";
$text.= "ABCDEFGH";
echo "<table><tr><td><table>";
for($a=0; $a<strlen($text); $a++) {
$chr = substr($text,$a,1);
$bits = array(128,64,32,16,8,4,2,1);
$store = array(0,0,0,0,0,0,0,0);
$inp = ord($chr);
for($x=0; $x<count($bits); $x++) {
if($bits[$x] <= $inp) {
$inp = $inp - $bits[$x];
$store[$x] = 1;
} else {
$store[$x] = 0;
}
}
$store_rvs = array_reverse($store);
if($a % 8 === 0) {
echo "</table></td><td><table>";
}
echo "<tr>";
for($b=0; $b<count($store_rvs); $b++) {
if($store_rvs[$b] == '1') {
echo "<td class='cell blk'></td>";
} else {
echo "<td class='cell wht'></td>";
}
}
echo "</tr>";
}
echo "</table></td></tr></table>";

How to display this query result in 4 columns
<?php
$direction = $_POST['direction'];
$sumword = $_POST['sumword'];
$length = $_POST['length'];
$con = mysql_connect("localhost","elsha","12q(5PSZ.");
$db = mysql_select_db("elsha",$con);
$query = "SELECT answer FROM words WHERE direction = '$direction' AND sumword = '$sumword' AND sumletter = '$length'";
$result = mysql_query($query);
if(mysql_error()) {
//check that no error has occurred first; take this out in production or make more graceful handling
die(mysql_error());
}
if(mysql_num_rows($result) == 0) {
echo "No Results";
} else {
while($row = mysql_fetch_array($result)) {
echo '<img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'].'<br>';
}
}
?>
like this :
result1 result2 result3 result4
result5 result6 result7 result8
Try this
$i = 0;
while($row = mysql_fetch_array($result)) {
echo '<img src="/images/'. $row['0'].'.jpg"> ';
$i++;
if($i % 4 == 1 && $i!=1){
echo '<br>';
}
}
Use flag like
$flag=0;
while($row = mysql_fetch_array($result)) {
if(($flag%4)==0) {
echo '<tr>';
}
echo '<td><img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'].'</td>';
if(($flag%4)==3) {
echo '</tr>';
$flag=-1;
}
$flag++;
}
replace your while with the following code. try this
$a=1;
while($row = mysql_fetch_array($result)) {
if($a%4==0) {
echo '<img src="/images/'. $row['0'].'.jpg">'. $row['0'].'<br>';
} //4th line with break
else {
echo '<img src="/images/'. $row['0'].'.jpg"> '. $row['0'].' '; // prints first 3 lines
}
$a=$a+1;
}
I think you are trying to display the image name too below the image. Try this:
$i = 1;
while($row = mysql_fetch_array($result)) {
echo '<div class="imgs">';
echo '<img src="/images/'. $row['0'].'.jpg"><br> '. $row['0'];
echo '</div>';
if ($i === 4) {
echo '<div class="clear"></div>';
$i = 1;
} else {
$i++;
}
}
and then style div's
.imgs {
float: left;
/* other styles */
}
.clear {
clear: both;
}
My website currently ignores the first two images you place into the database and then proceeds to add images going across 5 columns and then moving down to the next row.
Update: Now it shows 3 of the 4 images in the database. Skips one image.
<?php
$i = 1;
echo "<table>";
while ($row = $Recordset2->fetch_object()) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row_Recordset2['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {
$i = 1;
echo "</tr>";
} else {
$i++;
}
}
echo "</table>";
?>
This is what my database looks like
http://i.stack.imgur.com/IFba8.jpg
This is what my website shows
http://i.stack.imgur.com/Wf7E1.jpg
Try this:
<?php
$i = 1;
echo "<table>";
while ($row = $Recordset2->fetch_object()) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {
$i = 1;
echo "</tr>";
} else {
$i++;
}
}
echo "</table>";
?>
Please try this.
<?php
$i = 1;
echo "<table>";
while ( $row = $Recordset2->fetch_object() ) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row_Recordset2['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {

}
}

?>
echo "<table title='mxit:table:full' style='width: 100%' width='100%'><colgroup span='2' width='50%'></colgroup>";
foreach($arr['chart_data'] as $key => $element){

foreach($element as $subkey => $subelement){
// $subelement =chop($subelement,'DIRECTSegment');
if($subkey++ < 2) {
if($key == 0)

How do i take only 10 elements of my array $arr['chart_data'] at a time ?
Set a counter, and then break the loop when $count hits 10.
$count = 0;
/* loop here */
if ($count == 10) break;
Anyway for all those who gave me negative votes and for my own betterment i solved my issue:
Here is what i did:
$totalfiles = count($arr['chart_data']);
$limit = 10;
$pages = ceil($totalfiles / $limit);
if (!isset($_GET['startrow']) or!is_numeric($_GET['startrow'])) {
//we give the value of the starting row to 0 because nothing was found in URL
$startrow = 0;
//otherwise we take the value from the URL
} else {
$startrow = (int) $_GET['startrow'];
}
echo "<table title='mxit:table:full' style='width: 100%' width='100%'><colgroup span='2' width='50%'></colgroup>";
$data = array_slice($arr['chart_data'], $startrow, 10); // same as offset 0 limit 50 in sql
foreach($data as $key => $element) {
echo "<tr>";
foreach($element as $subkey => $subelement) {
$subelement = chop($subelement, 'DIRECTSegment');
if ($subkey++ < 2) {
if ($key == 0 && $startrow == 0) {
echo "<td align='center;' style='color:white;'>$subelement</td>";
} else if ($subkey == 1) {
echo "<td align='center;' style='color:white;'>$subelement</td>";
} else {
echo "<td align='center;' style='color:white;'><a href='getdata.php?key=$key'>".$subelement.
"</a></td>";
}
}
}
echo "</tr>";
}
echo "</table>";
/* free result set */
$result - > close();
}
/* close connection */
$mysqli - > close();
//now this is the link..
echo '<a href="'.$_SERVER['PHP_SELF'].
'?startrow='.($startrow + 10).
'">Next</a>';
$prev = $startrow - 10;
//only print a "Previous" link if a "Next" was clicked
if ($prev >= 0)
echo ' <a href="'.$_SERVER['PHP_SELF'].
'?startrow='.$prev.
'">Previous</a>';
Implemented paging and using array slice to display 10 elements at a time.
Thanks for all the help
i got this script. it looks into a file and read all the lines and put it nicely in a table.. what i need to do now is to take all the table data and split it into two tables ..
eg. if their is 100 rows.. then instead of one long list, i will get 50 data in one table and the other 50 in the other table...
enter code here<?php
if(isset ($_GET['type']))
{
$otype = $_GET['type'];
}
else
{
$otype = 'm';
}
$statusFile = "d:\\CLIENTS\\status.txt";
$file_handler = fopen($statusFile, "r");
// read the contents
$contents = fread($file_handler, filesize($statusFile));
// close the file
fclose($file_handler);
if (strcasecmp($otype, "m") == 0)
{
echo $contents;
}
else
{
$lines = explode("\n",$contents);
$frow = explode(",", $lines[0]);
if (strcmp($frow[1],"1") == 0)
{
echo "Update Status: <b>Complete</b>";
//to count total lines in txt file
$statusFile = "d:\\CLIENTS\\status.txt";
$line = count(file($statusFile));
echo "There are".$line."lines in";
}
else
{
echo "Update Status: <b>Incomplete</b>";
}
echo "<table border=\"1\">";
for ($count = 1; $count < sizeof($lines); $count++)

$fields = explode(",",$lines[$count]);
$sz = sizeof($fields);
if ($sz > 1)
{
$str = "OK";
echo "<tr>";
echo "<td>" . $fields[0] . "</td>";
echo "<td>" . $fields[1] . "</td>";

Use a foreach instead of a for and $count to calculate if it is needed to echo a table tag. $count is only incremented when a row was inserted.
<style>
div.container {
width: 100%; /* Change the width to the desired width */
padding: 0;
}
div.container table {
width: 50%; /* Change the width to half of the width of the div */
margin: 0;
float: left;
}
</style>
<?php
if(isset ($_GET['type']))
{
$otype = $_GET['type'];

else
{
$otype = 'm';

$file_handler = fopen($statusFile, "r");
// read the contents
$contents = fread($file_handler, filesize($statusFile));

Hello i'm having problems adding numbered rows/serial numbers to my database query result. I've used $number to collect the actual number of rows.
Then another problem i'm trying to avoid is: Numbering of Column Headers.
Thanks for the help.
<?php
$number = mysql_num_rows($query);
for ($serial = 0; $serial < $number; $serial++)
{
echo "<tr>". $serial ."</tr>";
}
for ($i = 0; $i < $number_cols; $i++)
{
echo "<th>" . mysql_field_name($query, $i) . "</th>\n";
}
while ($row = mysql_fetch_row($query))
{
echo "<tr align=center>\n";
for ($i = 0; $i < $number_cols; $i++)
{
echo "<td>";
if (!isset($row[$i]))
{
echo "NULL";
}
else
{
echo $row[$i];
}
echo "</td>\n";
}
echo "</tr>\n";
}
echo "</table>";
echo "</span>";
echo "</div>";
?>
trying my best to get something sane out of your terrific code.
<?php
$serial = 1;
while ($row = mysql_fetch_row($query))
{
echo "<tr align=center>\n";
echo "<td>";
echo $serial++;
echo "</td>\n";
foreach ($row as $value)
{
echo "<td>$value</td>\n";
}
echo "</tr>\n";
}
