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; }

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>';
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.
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);

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($result);
}
I'm using a foreach loop to echo out some values from my database, I need to strip the last comma from the last loop if that makes sense.
My loop is just simple, as below
foreach($results as $result){
echo $result->name.',';
}
Which echos out
result,result,result,result,
I just need to kill that pesky last comma.
Better:
$resultstr = array();
foreach ($results as $result) {
$resultstr[] = $result->name;
}
echo implode(",",$resultstr);
1. Concat to string but add | before
$s = '';
foreach ($results as $result) {
if ($s) $s .= '|';
$s .= $result->name;
}
echo $s;
2. Echo | only if not last item
$s = '';
$n = count($results);
foreach ($results as $i => $result) {
$s .= $result->name;
if (($i+1) != $n) $s .= '|';
}
echo $s;
3. Load to array and then implode
$s = array();
foreach ($results as $result) {
$s[] = $result->name;
}
echo implode('|', $s);
4. Concat to string then cut last | (or rtrim it)
$s = '';
foreach ($results as $result) {
$s .= $result->name . '|';
}
echo substr($s, 0, -1); # or # echo rtrim($s, '|');
5. Concat string using array_map()
echo implode('|', array_map(function($result) { return $result->name; }, $results));
$result_names = '';
foreach($results as $result){
$result_names .= $result->name.',';
}
echo rtrim($result_names, ',');
I've been having the same issue with this similar problem recently. I fixed it by using an increment variable $i, initializing it to 0, then having it increment inside the foreach loop. Within that loop place an if, else, with the echo statement including a comma if the $i counter is less than the sizeof() operator of your array/variable.
I don't know if this would fix your issue per se, but it helped me with mine. I realize this question is years-old, but hopefully this will help someone else. I'm fairly new to PHP so I didn't quite understand a lot of the Answers that were given before me, though they were quite insightful, particularly the implode one.
$i=0;
foreach ($results as $result) {
$i++;
if(sizeof($results) > $i) {
echo $result . ", ";
} else {
echo $result;
}
}
In modern PHP, array_column() will allow you to isolate a column of data within an array of objects.
Code: (Demo)
$results = [
(object)['name' => 'A'],
(object)['name' => 'B'],
(object)['name' => 'C']
];
echo implode(',', array_column($results, 'name'));
Output:
A,B,C
That said, since you are iterating a result set, then you may be better served by calling a CONCAT() function in your sql, so that the values are already joined in the single value result set.
If you are processing a collection in Laravel, you can pluck() and implode():
$collection->pluck('name')->implode(',')
$arraySize = count($results);
for($i=0; $i<$arraySize; $i++)
{
$comma = ($i<$arraySize) ? ", " : "";
echo $results[$i]->name.$comma;
}
Not as pretty, but also works:
$first=true;
foreach($results as $result){
if(!$first) { echo ', '; }
$first=false;
echo $result->name;
}
Another smart way is:
foreach($results as $result){
echo ($passed ? ',' : '') . $result->name;
$passed = true;
}
In this case at first loop $passed is NULL and , doesn't print.
I know this is an old thread, but this came up recently and I thought I'd share my alternate, cleaner way of dealing with it, using next().
$array = array("A thing", "A whatsit", "eighty flange oscillators");
foreach( $array as $value ){
echo $value;
$nxt = next($array);
if($nxt) echo ", "; // commas between each item in the list
else echo ". And that's it."; // no comma after the last item.
}
// outputs:
// A thing, A whatsit, eighty flange oscillators. And that's it.
play with it here
I have to do this alot because I'm always trying to feed numbers in to jplot, I find its easier to put the comma in the front of the loop like so:
foreach($arrayitem as $k){ $string = $string.",".$k;
}
and then chop off the first character (the comma) using substr, it helps if you know a guestimate of long your string will be, I'm not sure what the limit on substr max character is.
echo substr($a,1,10000000);
hope this helps.
$a[0] = 'John Doe';
$a[1] = 'Jason statham';
$a[2] = 'Thomas Anderson';
$size = count($a);
foreach($a as $key=>$name){
$result .= $name;
if($size > $key+1) $result .=', ';
}
echo $result;
<?php
$return = array(any array)
$len = count($return);
$str = '';
$i = 1;
foreach($return as $key=>$value)
{
$str .= '<a href='.$value['cat_url'].'>'.$value['cat_title'].'</a>';
if($len > $i)
{
$str .= ',';
$i = $i+1;
}
}
echo $str;
?>
<?php
$i = 1;
$count = count( $results );
foreach( $results as $result ) {
echo $result->name;
if ( $i < $count ) echo ", ";
++$i;
}
?>
This is what I normally do, add a comma before the item rather than after, while ignoring the first loop.
$i = 0;
$string = '';
foreach($array as $item){
$string .= ($i++ ? ',' : '').$item;
}
First get all the output by using output buffering. Then, trim the comma and display it. So, do it like this:
ob_start();
foreach($results as $result)
{
echo $result->name.',';
}
$output = ob_get_clean();
echo rtrim($output, ',');
The output buffering method helps if the inside loop is very big (and OP is posting here just for brevity), then using OB is easier without changing the internals of the loop.
