foreach does a nice job if you want the results identical each time.
What can you use to change the formatting of the results dependent on
the number of results.
Here's an example:
foreach ( $authors[$bookID] AS $authorID => $authorData ) {
# Display the
echo "{$authorData['first_name']}
{$authorData['last_name']}\n";
}
will echo - Joe Boe John Blue Andy Candy etc depending on how many rows
we have.
What I want is: Joe Boe, John Blue, Andy Candy & Hans Stick ( separated
by commas, except for the last one which is separated with & .
I thought of passing a variable to the foreach and then using if
elseif... but that can't work because the variable is reset to 0 after
each pass.
Can't get switch to do it (maybe I don't understand it right.
Help ?
your answer lies with not replacing foreach to make your life/output better. But with how the data is prepared and
handed off to the foreach statement.
I am guessing that what you want would be something like this.
Since this looks like a snippet of code I sent you the other day, I will snag it "complete" from the other thread.
<?php
...
# Test to see if the book has any authors
if ( isset($authors[$bookID]) ) {
# Tell us how many authors we found
echo 'Found: ', count($author[$bookID]), ' authors';
# Create an array that will hold the output from the DB.
$aList = array();
# Loop through the authors
foreach ( $authors[$bookID] AS $authorID => $authorData ) {
# Add all the authors to that new array
$aList[] = "{$authorData['last_name']}, {$authorData['first_name']}";
}
# Sanitize the output
$aList = array_map('htmlspecialchars', $aList);
# Get a count of how many authors their is.
$tAuthors = count($aList);
# If more then one, do...
if ( $tAuthors > 1 ) {
# Take the last one off, so we can handle it differently
$last_author = array_pop($aList);
echo join(', ', $aList), ' & ', $last_author;
# If only one, then do...
} elseif ( $tAuthors == 1 ) {
echo join('', $aList);
}
echo '<br />';
} else {
echo 'No authors found';
}
...
?>
