PHP Fatal error: Call to undefined function bcmul()_PHP教程

This article will introduce to you the solution to PHP Fatal error: Call to undefined function bcmul(). I hope this tutorial will be helpful to all students.

While migrating a server that handles online payments, it was discovered that payments could not be made.

1.PHP version is 5.3.3
2. The system is Red Hat 4.1.2-54
Checking the error log of apache, I found that a function bcmul() in the encrypted file reported an error:

PHP Fatal error: Call to undefined function bcmul() in /php_rsa.php on line xxx
This function is one of the PHP math extensions. Use bcscale() to set the global default number of decimal places. The specific usage is as follows:

echo bcmul('1.34747474747', '35', 3); // 47.161
echo bcmul('2', '4'); // 8
?>

Solution:

Use the following command:

yum install php-bcmath

It is installed.

If the following situation occurs:

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 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package php-bcmath.x86_64 0:5.1.6-40.el5_9 set to be updated --> Processing Dependency: php-common = 5.1 .6-40.el5_9 for package: php-bcmath --> Running transaction check ---> Package php-common.x86_64 0:5.1.6-40.el5_9 set to be updated --> Processing Conflict: php53-common conflicts php-common --> Finished Dependency Resolution php53-common-5.3.3-13.el5_9.1.x86_64 from installed has depsolving problems --> php53-common conflicts with php-common Error: php53- common conflicts with php-common 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
Just use yum update and then yum install php53-bcmath

Options for this function in php.ini:

[bcmath] ; Number of decimal digits for all bcmath functions. ; http://www.php.net/manual/en/bc.configuration.php#ini.bcmath.scale bcmath.scale = 0
