The default version can be changed from the alwaysdata administration, under Environment > PHP. This is the version that is especially used when you start
Versions are not necessarily already installed.
You can view the Apache error logs from file
$HOME/admin/logs/apache/apache.log. These logs sometimes comprise important information returned by PHP.
A php.ini option lets you get PHP error logs by adding the following directives:
log_errors = On error_log = /home/[myaccount]/[path_to_log_file]
By default, the
php.ini file activates a number of essential extensions and defines some basic parameters. This file is accessible in read from the following location
$HOME/admin/config/php/php.ini. Here is its content (for an account configured on PHP version 7.2):
; Core settings max_execution_time = 120 max_input_time = 60 memory_limit = 256M post_max_size = 256M upload_max_filesize = 256M output_buffering = 4096 expose_php = Off default_socket_timeout = 10 date.timezone = "Europe/Paris" mysql.default_socket = /run/mysqld/mysqld.sock session.save_path = /home/sandbox/admin/tmp upload_tmp_dir = /home/sandbox/admin/tmp ; Extensions extension_dir = "/usr/alwaysdata/php/7.2.12/lib/php/extensions/no-debug-non-zts-20170718" extension = ctype.so extension = curl.so extension = dom.so extension = gd.so extension = gettext.so extension = iconv.so extension = json.so extension = mbstring.so extension = openssl.so extension = posix.so extension = simplexml.so extension = tokenizer.so extension = xml.so extension = xmlwriter.so extension = xsl.so extension = zip.so extension = zlib.so extension = mysqli.so extension = pgsql.so extension = pdo.so extension = pdo_mysql.so extension = pdo_pgsql.so extension = fileinfo.so extension = phar.so ; Zend extensions zend_extension = /usr/alwaysdata/php/7.2.12/lib/php/extensions/no-debug-non-zts-20170718/opcache.so
To change this
php.ini, go to the Environment > PHP section (or if you want to manage it at the website level in Web > Sites). All of the directives that you define will be added to the initial
php.ini file and can therefore overwrite the default values. There is no limit to what you can define, every PHP option is accessible.
You can also create
.user.ini files to only apply parameters to some directories.
Managing PHP versions per site results in a higher RAM consumption per account. Websites cannot then share PHP processes. It is therefore recommended :
