PHP settings errors
This article provides solutions for PHP settings errors.
PHP memory limit error
The readiness checks makes sure you have at least 1GB of memory set aside for PHP processes. This setting should be sufficient for most installations, including installing optional sample data. However, we recommend at least 2GB for debugging.
To increase your PHP memory limit:
Log in to your Adobe Commerce server.
Locate your php.ini
file using the following command:
bash $ php --ini
As a user with root
privileges, use a text editor to open the php.ini
specified by Loaded Configuration File
.
Locate memory_limit
.
Change it to a value of 2GB
for normal use and debugging.
Save your changes to php.ini
and exit the text editor.
Restart your web server. Examples follow:
CentOS: service httpd restart
Ubuntu: service apache2 restart
nginx (both CentOS and Ubuntu): service nginx restart
Try the installation again.
Configurations with a high number of storeviews, products, attributes, or options can generate forms that exceed the preset PHP limit. If the number of values sent surpasses the max-input-vars
limit set within php.ini
(default is 1000), the remaining data is not transferred and those database values do not get updated. When this occurs, a warning appears in the PHP log:
PHP message: PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini.
There is no 'proper' value for max-input-vars
; it depends on the size and complexity of your configuration. Modify the value in the php.ini
file as needed. See Required PHP settings .
xdebug maximum function nesting level error
See During installation, xdebug maximum function nesting level error .
Errors display when you access a PHTML template
Error text is typically:
Parse error: syntax error, unexpected 'data' (T_STRING)
Multiple templates have syntax for support abstract level on templates (use different templates engines like Twig) wrapped in <% %>
tags, like this template for displaying a product image:
<img
class="product-image"
src="<%- data.url %>"
data-position="<%- data.position %>"
alt="<%- data.label %>" />
More information about asp_tags .
Edit php.ini
and set asp_tags = off
. For more information, see Required PHP settings .
