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:

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

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
