The table below displays all words in the string $commentstring. How can I exclude certain articles, prepositions, and verbs like "the, of, is"?
$words = explode(" ", $commentstring);
$result = array();
arsort($words);
foreach($words as $word) {
if(!is_numeric($word)){
$result[$word]++;
arsort($result);
}
}
echo "<table>";
foreach($result as $word => $count1) {
echo '<tr>';
echo '<td>';
echo "$word";
echo '</td>';
echo '<td>';
echo "$count1 ";
echo '</td>';
echo '</tr>';
}
echo "</table>";
Several ways to do this, if you still want to count them but just not display them in the table, you could do:
$blacklist = array('the', 'is', 'a');
foreach($result as $word => $count1)
{
if (in_array($word, $blacklist)) continue;
...
if you don't even want to count them, you can skip them in a similar way in your counting loop.

Ok i have a string which needs to be splitted 2 times.
First time by whitespaces and second time by commas. So i can put it in a table.
I managed to split the string by whitespaces and put it in the first column of the table but i struggle to split it for the second time and put the values in the right column.
Here the snippets of what i already got:
<?php for ($i = 0; $i < sizeof($volumes); $i++) {
echo "<tr><td>" . $volumes[$i] . "</td></tr>";
} ?>
When you render the table rows you should split each volume by comma. I don't understand exactly all the retrieved rows or what is the logic behind your code but this bunch of code should do what you need:
<?php
for ($i = 0; $i < sizeof($volumes); $i++) {
echo '<tr>';
$volumeData = explode(',', $volumes[$i]);
foreach ($volumeData as $volume) {
echo '<td>' . $volume . '</td>';
}
echo '</tr>';
}
?>
Are you sure the string you provided is accurate? I think there's a coma missing between the size of SystemReserved and the label of the next drive. If that's the case - the code should be something like this:
First we 'explode' the string to create an array, then use array chunk to split it into arrays with seven entries each. And then render it:
$string = 'L,Logs,NTFS,Healthy,OK,9.73,9.77 ,SystemReserved,NTFS,Healthy,OK,0.16,0.49 ,C,LocalDisk,NTFS,Healthy,OK,18.19,29.74';
$array = explode(',', $string);
$results = array_chunk($array, 7, true);
?>
<table id="tbl_basic_volumes">
<tr>
<th>Buchstabe:</th>
<th>Name:</th>
<th>Filesystem:</th>
<th>Health Status:</th>
<th>Operational Status:</th>
<th>Freier Speicherplatz:</th>
<th>Gesamter Speicherplatz:</th>
</tr>
<?php
foreach ($results as $result) {
echo '<tr>';
foreach ($result as $entry) {
echo '<td>'.$entry.'</td>';
}
echo '</tr>';
}
?>
</table>
You can escape the inner foreach loop using implode.
$str = "L,Logs,NTFS,Healthy,OK,9.73,9.77 ,SystemReserved,NTFS,Healthy,OK,0.16,0.49 C,LocalDisk,NTFS,Healthy,OK,18.19,29.74";
$rows = explode(' ', $str);
foreach ($rows as $row) {
echo '<tr><td>' . implode('</td><td>', explode(',', $row)) . '</td></tr>';
}
Or even replacing commas with </td><td> will also work:
$str = "L,Logs,NTFS,Healthy,OK,9.73,9.77 ,SystemReserved,NTFS,Healthy,OK,0.16,0.49 C,LocalDisk,NTFS,Healthy,OK,18.19,29.74";
$rows = explode(' ', $str);
foreach ($rows as $row) {
echo '<tr><td>' . str_replace(',', '</td><td>', $row) . '</td></tr>';
}
I have a text file generated from our banking software which looks like this:
This is my code to print the text file contents line by line:
<?php
$myFile = "20151231.txt";
$lines = file($myFile);
foreach ($lines as $line_num) {
echo htmlspecialchars($line_num)."<br>";
}
It prints like this:
I just want each line that starts with:
====>
I want everything else deleted.
I tried a lot but failed to print lines with the columns separated as it looks in the text file image.
This is how I want each line to print:
====>0518 Intt on Consumer Loan 401010707 108,149.00
Your assistance regarding this will be highly appreciated.
You can print it as a table:
<?php
$myFile = "20151231.txt";
$lines = file($myFile);
echo '<table>';
foreach ($lines as $line_num) {
if (strpos($line_num, '====>') !== false) {
$str = trim(htmlspecialchars($line_num));
echo '<tr>';
echo '<td>' . getColumnText("/====>\d+/", $str) .'</td>';
echo '<td>' . getColumnText("/\s([a-zA-Z\s]+)/", $str) .'</td>';
$secondCol = getColumnText("/\s([0-9]+)/", $str);
echo '<td>' . $secondCol .'</td>';
$thirdCol = end(explode(" ", $str));
if (trim($secondCol) === $thirdCol) {
echo '<td style="text-align:right">' . str_repeat(" ", 10) .'</td>';
} else {
echo '<td style="text-align:right">' . str_repeat(" ", 10) . $thirdCol .'</td>';
}
echo '</tr>';
}
}
echo '</table>';
function getColumnText($pattern, $str) {
preg_match($pattern, $str, $matches);
return trim(current($matches));
}
yes you can do that with strpos or regularexpression and i am just writing code using strpos
<?php $myFile = "text.txt";
$lines = file($myFile);
echo '<table cellspacing="20">';
$linenum = 1;
foreach ($lines as $line_num) {
echo '<tr>';
// check whether line conatain ====>, if you want to check starting of line then just put 0 instead of false in following condition
if(strpos($line_num,'====>')!==false)
{
$texts= substr($line_num, strpos($line_num,'====>')+5);
$textarr = explode(" ", $texts);
echo '<td>'.$linenum.'</td>';
foreach($textarr as $arr)
{
echo '<td>'.$arr.'</td>';
}
$linenum++;
//print_r($textarr);
//echo htmlspecialchars($line_num)."<br>";
}
}
echo '<table>';
I am trying to pull data from a table in PHPmyadmin and convert it to an HTML table based on some customer form input which filters out unneeded rows. The code below does that fine. The issue is that two of my columns need to contain links.
It would be easy enough to use PHP to change the table data into the link using a strtolower() and str_replace() to remove spaces, then concatinating the "www.website.com/" and the ".html". But I'm using a foreach loop to get all of the rows that I need and I don't know how to only alter one value per row.
I have tried using "Broswer Display Transformations" and "Input Transformations" in PHPmyadmin, but that only seems to affect the data in PHPmyadmin and not when I access the data via PHP.
My current code:
//* Code for Table
$query = "SELECT $searchFields FROM `hose_reels` $searchPhrase ORDER BY `model` ASC";
$result = mysqli_query($cxn,$query);
if ($row[$key] != "0") {
echo '<table width="100%" border="1" class="table"><tr>';
$row = $result->fetch_assoc();
foreach ($row AS $key => $value) {
$key = ucwords(str_replace('_', ' ', $key));
echo "<th>" . $key . "</th>";
}
echo "</tr>";
$result2 = mysqli_query($cxn,$query);
while($row = $result2->fetch_assoc()) {
echo "<tr>";
foreach ($row AS $key => $value) {
$row['$key'] = $value;
echo "<td>$row[$key]</td>";
}
echo "</tr>";
}
echo "</table>";
}
else {
echo "<p>No results match your selection. Please broaden your search.</p>";
}
Just add <a> tag in your php code. Below is the code. One more thing you have error in echo "<td>$row[$key]</td>"; line . it prints <td>$row[$key]</td> not the result you are fetching from DB.
echo '<table width="100%" border="1" class="table"><tr>';
$row = $result->fetch_assoc();
$i = 1;
foreach ($row AS $key => $value) {
$key = ucwords(str_replace('_', ' ', $key));
if($i == 1 || $i ==3){
echo "<th><a href='".key ."'" . $key . "</a></th>";
}else{
echo "<th>" . $key . "</th>";
}
$i++;
}
echo "</tr>";
$result2 = mysqli_query($cxn,$query);
$j =1;
while($row = $result2->fetch_assoc()) {
echo "<tr>";
foreach ($row AS $key => $value) {
$row['$key'] = $value;
if($i == 1 || $i ==3){
echo "<td><a href='".$row[$key]."'".$row[$key]."</a></td>";
}else{
echo "<td>$row[$key]</td>";
}
}
echo "</tr>";
}
echo "</table>";
In the table below, $count1 is a numerical value. How do I sort the table by $count1 descending?
$words = explode(" ", $commentstring);
$result = array_combine($words, array_fill(0, count($words), 0));
foreach($words as $word) {
$result[$word]++;
}
echo "<table>";
foreach($result as $word => $count1) {
echo '<tr>';
echo '<td>';
echo "$word";
echo '</td>';
echo '<td>';
echo "$count1 ";
echo '</td>';
echo '</tr>';
}
echo "</table>";
After this line put asort()
$words = explode(" ", $commentstring);
asort($words);
You could also use sort($array_var, SORT_DESC);
http://us.php.net/manual/en/function.sort.php
EDIT:
Usage
$foo = array('bar', 'car', 'apple', 'food', 'banana');
sort($foo, SORT_DESC);
Thanks to the responders... they guided me in the right direction. I finally got this to work:
foreach($words as $word) {
$result[$word]++;
arsort($result);
}
The code below returns a table with a row for every word or number that appears in $commentstring. Each word or number appears as $word in the table below. How can I exclude numbers?
$words = explode(" ", $commentstring);
$result = array_combine($words, array_fill(0, count($words), 0));
arsort($words);
foreach($words as $word) {
$result[$word]++;
arsort($result);
}
echo "<table>";
foreach($result as $word => $count1) {
echo '<tr>';
echo '<td>';
echo "$word";
echo '</td>';
echo '<td>';
echo "$count1 ";
echo '</td>';
echo '</tr>';
}
echo "</table>";
You could use is_numeric to check whether each $word is a number, and only insert it into your array if it isn't.
if (!is_numeric($word)) {
if (!isset($result[$word]))
$result[$word] = 0;
$result[$word]++;
arsort($result);
}
Edit: Also, do you really need to sort the array on each increment? Why not just sort it at the end?
If i'm understanding your question right you can check if the $word var is a number by using the is_numeric() function
foreach($result as $word => $count1) {
if(is_numeric($word)) { continue; }
