I have an array and I want to generate a message out of them. If I use join(', ', $response)
, I get file1.jpg, file2.jpg, file3.jpg
. Is it possible to replace the last comma so the message would be file1.jpg, file2.jpg AND file3.jpg
?
This should work;
<?php
$response=['file1.jpg','file2.jpg','file3.jpg'];
$response=array_reverse($response);
$arr=$response[1].' AND ' .$response[0];
for ($i=2; $i < count($response); $i++) {
$new[]=$response[$i];
}
array_push($new, $arr);
echo join(", ",$new);
You can use array_slice
to get all the elements in the array but the last one and make a special case for it :
function formatList($response)
{
if(count($response) == 0)
return '' ;
if(count($response) == 1)
return $response[0] ;
else
return join(', ', array_slice($response, 0, count($response)-1)) . ' AND ' . end($response);
}
substr_replace
replace a portion of a string by position and length, strrpos
find position of the last comma.
$response = ['file1.jpg', 'file2.jpg', 'file3.jpg'];
$out = join(', ', $response);
echo substr_replace($out, " AND", strrpos(($out), ','), 1);
