Replace the last comma with &

Question

I searched everywhere but cannot find a solution that works for me.

I have the following:

$bedroom_array = array($studio, $one_bed, $two_bed, $three_bed, $four_bed);

In this example we can say:

$studio = '1';
$one_bed = '3';
$two_bed = '3';

Then I use the implode function to put a comma between all the values:

$bedroom_list = implode(", ", array_filter($bedroom_array));
echo $bedroom_list;

Then issued:

1, 2, 3

What I want to do is find the last comma in the line and replace it with &, so it will read:

1, 2 and 3

The string will not always be so long; it can be shorter or longer, for example. 1, 2, 3, 4, etc. I studied using substr but not sure if this will work for what I need?

Answer 5

$bedroom_list = implode(", ", array_filter($bedroom_array));

$vars =  $bedroom_list;

$last = strrchr($vars,",");

$last_ = str_replace(",","&",$last);

echo str_replace("$last","$last_",$vars);

Answer 6

<?php
$string = "3, 4, 5";
echo $string = preg_replace('/,( \d)$/', ' &\1', $string);
?>

Answer 7

strrpos finds the last occurrence of the specified string. $ str = '1, 2, 3';

$index = strrpos( $str, ',' ); 
if( $index !== FALSE )
    $str[ $index ] = '&';
