php5.2中cal_days_in_month的问题

liugehao · #1

编译安装的php5.2
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-xml --with-mysql=/usr/local/mysql' --with-pgsql=/usr/local/pgsql

用cal_days_in_month(0,$date['mon'],$date['year']);
提示：Call to undefined function cal_days_in_month()

用 PHP手册上例子也是同样错误
<?php
$num = cal_days_in_month(CAL_GREGORIAN, 8, 2003); // 31
echo "There was $num days in August 2003";
?>
请问，是什么原因？

cal_from_jd(）也用不了，是不是编译时要加什么选项？

To get these functions to work, you have to compile PHP with --enable-calendar.
