I am using this code
<?php
foreach($rows as $row) {
echo "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>, ";
}
?>
The problem is that the comma and space (,<space>) are added to even the last $row. What is the simplest method to prevent this? I had an idea to check the size of the array etc. but not sure if this would be over complicating it.
You can do this -
<?php
$links= array();
foreach($rows as $row) {
$links[]= "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>";
}
echo implode(', ', $links);
?>
Or
<?php
$i = 0;
$total = count($rows);
foreach($rows as $row) {
echo "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>";
$i++;
if($i < $total)
echo ",";
}
?>
Or RiggsFolly's answer is another option.
There is a simpler solution
<?php
$htm = '';
foreach($rows as $row) {
$htm .= "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>, ";
}
rtrim($htm,', ');
echo $htm;
?>
If you want to get complicated then you could do :-
<?php
$crows = count($rows) - 1;
foreach($rows as $i => $row) {
echo "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>";
echo ( $crows > $i ) ? ', ' : '';
}
?>
You can do it with strings with two ways:
1) Use rtrim()
<?php
$str = '';
foreach($rows as $row) {
$str .= "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>, ";
}
echo rtrim($str, ', ');
?>
2) Take an array of links and implode() by space and comma.
<?php
$arr = array();
foreach($rows as $row) {
$arr[] = "<a href=index.html?id=" . $row['id'] . ">" . $row['name'] . "</a>, ";
}
echo implode(', ', $arr);
?>
