Configuration Files

Directory Structure

PHM installs each PHP version in a separate directory:

/opt/php/8.5/
├── bin/                          # Executables
│   ├── php
│   ├── phpize
│   ├── php-config
│   └── pecl
├── sbin/
│   └── php-fpm                   # PHP-FPM
├── etc/

    └── no-debug-non-zts-*/       # Extension files (.so)
        ├── redis.so
        └── ...

CLI vs FPM Differences

PHM uses separate php.ini files for CLI and FPM:

Setting	CLI	FPM
memory_limit	-1 (unlimited)	128M
max_execution_time	0 (unlimited)	30
display_errors	On	Off

Changing memory_limit

For CLI

# Edit the CLI php.ini file
nano /opt/php/8.5/etc/cli/php.ini

# Or append to the file:
echo "memory_limit = 512M" >> /opt/php/8.5/etc/cli/php.ini

For FPM

# Edit the FPM php.ini file
nano /opt/php/8.5/etc/fpm/php.ini

# Or append to the file:
echo "memory_limit = 256M" >> /opt/php/8.5/etc/fpm/php.ini

# Restart PHP-FPM
phm fpm restart 8.5

Important

Remember to restart PHP-FPM after changing FPM configuration.

Managing Extensions

PHM makes it easy to enable and disable extensions:

Command	Description
phm ext list	List extensions
phm ext enable redis	Enable extension
phm ext disable xdebug	Disable extension
phm ext enable opcache --sapi fpm	Enable for FPM only

Extension Configuration Files

Extensions are configured via .ini files in the conf.d directory:

/opt/php/8.5/etc/conf.d/
├── 10-opcache.ini    # Loaded first (priority 10)
├── 20-redis.ini      # Loaded second (priority 20)
├── 20-igbinary.ini
└── 20-mongodb.ini

Loading order

The numeric prefix (10-, 20-) determines the extension loading order.

Example .ini Files

20-redis.ini

extension=redis.so

# 10-opcache.ini (uses zend_extension)
zend_extension=opcache.so
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
