问题：

How can I write two functions that would take a string and return if it starts with the specified character/string or ends with it? 我如何编写两个带字符串的函数，如果它以指定的字符/字符串开头或以它结尾，则返回？

For example: 例如：

$str = '|apples}';

echo startsWith($str, '|'); //Returns true
echo endsWith($str, '}'); //Returns true
