I get strange error messages when compiling PHP with --with-apxs_PHP Tutorial
There are two ways to check. First, when Apache built the apxs Perl program, for some reason, it did not include the correct compilation parameters. Edit your apxs (in /usr/local/apache/bin/apxs or /usr/sbin/apxs) and check the following lines:
my $CFG_CFLAGS_SHLIB = ' '; # substituted via Makefile.tmpl
my $ CFG_LD_SHLIB = ' '; # substituted via Makefile.tmpl
my $CFG_LDFLAGS_SHLIB = ' '; The line looks like:
my $CFG_CFLAGS_SHLIB = '-fpic -DSHARED_MODULE'; # substituted via Makefile.tmpl
my $CFG_LD_SHLIB = 'gcc'; # substituted via Makefile.tmpl
my $CFG_LDFLAGS_SHLIB = q( -shared);# substituted via Makefile.tmpl
The second possible cause only occurs on RedHat 6.1. There is a problem with the apxs configuration on RedHat, as follows:
my $CFG_LIBEXECDIR = 'modules'; # substituted via APACI install
If you see the above line, you should change it to the following line:
my $ CFG_LIBEXECDIR = '/usr/lib/apache'; # substituted via APACI install

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.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
