PHP is a widely-used general-purpose scripting language that is especially suited for
Web development. The PHP support is part of the camel-script
module.
To use PHP in your routes you need to add a dependency on
camel-script
to your project as shown in
Example 13, “Adding the camel-script dependency”.
Example 13. Adding the camel-script dependency
<!-- Maven POM File --> ... <dependencies> ... <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-script</artifactId> <version>${camel-version}</version> </dependency> ... </dependencies>
Table 7, “PHP attributes” lists the built-in attributes that are accessible when using PHP.
