You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
string bcmul ( string $left_operand , string $right_operand [, int $scale ] )
例子:
echo bcmul('1.34747474747', '35', 3); // 47.161
echo bcmul('2', '4'); // 8
?>
[bcmath]
; Number of decimal digits for all bcmath functions.
; http://www.php.net/manual/en/bc.configuration.php#ini.bcmath.scale
bcmath.scale = 0
PHP环境:
PHP版本为5.3.3
系统为Red Hat 4.1.2-54
查看apache的错误日志,发现是加密文件中一个函数bcmul()报错:
复制代码 代码如下:
PHP Fatal error: Call to undefined function bcmul() in /php_rsa.php on line xxx
解决办法:
使用如下命令:
复制代码 代码如下:
yum install php-bcmath
就安装好了。
如果出现下面这种情况:
复制代码 代码如下:
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.yun-idc.com
* extras: mirrors.yun-idc.com
* rpmforge: ftp.riken.jp
* updates: mirrors.yun-idc.com

就需要使用yum update 之后再yum install php53-bcmath就好了
顺便了解了一下,bcmath这个函数是PHP数学扩展中的一个。可以使用 bcscale() 来设置全局默认的小数位数,具体用法如下:
复制代码 代码如下:
string bcmul ( string $left_operand , string $right_operand [, int $scale ] )
例子:
复制代码 代码如下:
echo bcmul('1.34747474747', '35', 3); // 47.161
echo bcmul('2', '4'); // 8
?>
此函数在php.ini中的选项:
复制代码 代码如下:
[bcmath]
; Number of decimal digits for all bcmath functions.
; http://www.php.net/manual/en/bc.configuration.php#ini.bcmath.scale
bcmath.scale = 0
