Methods
- __call() : SchemaDiff
- __callStatic() : SchemaDiff
- compare() : SchemaDiff
- compareSchemas() : SchemaDiff
- compareTables() : TableDiff
- Compares the tables and returns the difference between them.
- diffColumn() : array<string|int, string>
- Returns the difference between the columns
- diffSequence() : bool
- diffTable() : TableDiff|false
- Returns the difference between the tables $fromTable and $toTable.
- detectRenamedColumns() : array<string, Column>
- Try to find columns that only changed their name, rename operations maybe cheaper than add/drop however ambiguities between different possibilities should not lead to renaming at all.
- detectRenamedIndexes() : array<string, Index>
- Try to find indexes that only changed their name, rename operations maybe cheaper than add/drop however ambiguities between different possibilities should not lead to renaming at all.
- doCompareSchemas() : SchemaDiff
- Returns a SchemaDiff object containing the differences between the schemas $fromSchema and $toSchema.
- isAutoIncrementSequenceInSchema() : bool
- normalizeColumns() : Table

Parameters
Tags
Return values
SchemaDiffcompareSchemas()
public
compareSchemas(Schema $fromSchema, Schema $toSchema) : SchemaDiff
Parameters
Return values
SchemaDiffcompareTables()
Compares the tables and returns the difference between them.
public

Parameters
Return values
TableDiffdiffColumn()
