passed var in to an array with a foreach loop – handy for string phasing in loops,
x2 birds – one stone! ;)
then just a matter of imploding back to variables.

below, working code for generating an array from variables to search-replace the last character in the last occurrence of strings.
=====================================================================
$arr = array(“apples taste delicious,”, “oranges are sweet,”, “lettuce tastes crunchy,”, “bananas are nice in deserts,”, “pears are tasty!,”, “mangoes are great for breakfast,”);
foreach ($arr as &$val){
$val[strlen($val)-1] = “Z”;
$val = ($val. PHP_EOL);
}
unset($v);
$var = implode(“”, $arr);
echo $var;
=====================================================================
Some food for coding thought: If calling $arr = file(“list-of-fruits.txt”); you will will need to set the negative coordinate (read-backward coordinate) to -3
ie: $val[strlen($val)-3] = “Z”;

For example: // not sure if you need to escape (\) the question mark symbol str_replace("\?","new symbol",$text); or str_replace("?","new symbol",$text); Use the str_replace function. For example:
// not sure if you need to escape (\) the question mark symbol

I got rid of the 1 at the end of the parameters and it works. Does this only work with an old version of PHP or something?
