PHP error category
PHP Extensions
Extension loading and availability.
PHP Extensions errors arise when extension loading and availability affect an executing PHP application or its supporting service. Use the exact signature and runtime context to narrow the cause before changing configuration.
The guides in this category separate code defects from environment differences, show focused diagnostics, and favor site-scoped corrections that preserve unrelated applications.
