推荐答案

Bogdan 正则表达式的修改版本，使用了负前瞻.

Modified version of Bogdan's regex using negative lookahead.

用 "number|Apple " 替换数字，除非它是字符串中的最后一个字符.

Replace number with "number|Apple " unless it is the last character in the string.

<?
$string = "Apple 123456";
echo preg_replace('/([0-9])(?!$)/', '$1|Apple ', $string);
?>

输出:Apple 1|Apple 2|Apple 3|Apple 4|Apple 5|Apple 6
