fix: cast string returns to int in MY_Migration#4560
Merged
Conversation
basename() returns string and database column values are strings, but get_latest_migration() and get_current_version() declare int return types. PHP 8.0+ enforces strict return types and no longer silently coerces strings to int, causing a TypeError on fresh installs. Fixes #4559

In `@app/Libraries/MY_Migration.php`:
- Line 28: get_latest_migration() is using basename() unnecessarily on the
migration version from MigrationRunner::findMigrations(); replace return (int)
basename(end($migrations)->version) with just casting the version: return (int)
end($migrations)->version, and optionally add a guard that checks if $migrations
is empty before calling end() to avoid errors (refer to get_latest_migration(),
MigrationRunner::findMigrations(), and getMigrationNumber()).

Remove redundant basename() around the migration version in get_latest_migration() (and optionally harden for empty discovery).
MigrationRunner::findMigrations()already sets$migration->versionto the migration number extracted from the migration filename (getMigrationNumber()), sobasename(end($migrations)->version)is unnecessary/unclear—use(int) end($migrations)->versioninstead.end($migrations)would only error iffindMigrations()returns an empty array (no matching migration files / namespace mismatch). In this repo there are many matching migrations underapp/Database/Migrations/, so this is likely safe; a guard is optional hardening.

Summary
basename()return to(int)inget_latest_migration()—basename()always returns a string, but the method declaresintreturn type$result->versionto(int)inget_current_version()— database column values are strings, but the method declaresintreturn typeFixes #4559
Root Cause
PHP 8.0+ enforces strict return types. On older PHP versions, strings were silently coerced to int. On PHP 8.4 (as used in the Docker image),
basename()returning"20240101000000"and$result->versionreturning a string from MariaDB both throwTypeErrorwhen the function declares: intas return type.This affects fresh installs most severely because
get_latest_migration()is called early in the migration setup flow.How to Test
