Changing PhpStorm properties
You can make PhpStorm work faster by editing the default Java Virtual Machine (JVM) settings. These operations require certain understanding of the JVM functionality and may cause unexpected problems. Therefore it is strongly recommended that you address the JetBrains Support whereupon you will be provided with detailed instructions regarding which settings you need to update and what values should be assigned to them.

PhpStorm makes it possible to change the *.vmoptions and the idea.properties files without editing them in the PhpStorm installation folder.
Managing the *.vmoptions file
To change the JVM options, choose on the main menu. PhpStorm creates a file .vmoptions and opens it in the editor. Update the file as required. For example, to increase PhpStorm heap size, modify the -Xmx setting.
The name of the generated .vmoptions file depends on your operating system:
-
phpstorm.exe.vmoptionsorphpstorm64.exe.vmoptionsfor Windows. -
phpstorm.vmoptionsorphpstorm64.vmoptionsfor Linux. -
phpstorm.vmoptionsfor macOS.
Managing the idea.properties file
To open the idea.properties file in the editor, choose . If the file does not exist yet, PhpStorm creates it and opens in the editor.
Example: Changing the case of unicode literals
PhpStorm allows defining whether non-ascii characters should use literals like '\u00AB' or '\00ab'.
This behavior is controlled by the idea.native2ascii.lowercase system property. By default, upper-case characters are used.
To use lower-case characters, open the idea.properties file in the editor and add the following line:
idea.native2ascii.lowercase=true
Specifying custom JDK, properties, or vmoptions files across platforms
A custom JDK, as well as *.properties and *.vmoptions files are specified across platforms in a unified way.
All launchers look at the following environment variables:
