PHP error category
Legacy PHP
Removed and historical behavior.
Legacy PHP errors arise when removed and historical behavior 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.
