Rule `binary_operator_spaces`¶

Binary operators should be surrounded by space as configured.

Configuration¶

`default`¶

Default fix strategy.

Allowed values: 'align', 'align_by_scope', 'align_single_space', 'align_single_space_by_scope', 'align_single_space_minimal', 'align_single_space_minimal_by_scope', 'no_space', 'single_space', null

Default value: 'single_space'

`operators`¶

Dictionary of binary operator => fix strategy values that differ from the default strategy. Supported are: =, *, /, %, <, >, |, ^, +, -, &, &=, &&, ||, .=, /=, =>, ==, >=, ===, !=, <>, !==, <=, and, or, xor, -=, %=, *=, |=, +=, <<, <<=, >>, >>=, ^=, **, **=, <=>, ??, ??=

Allowed types: array

Default value: []

Rule sets¶

The rule is part of the following rule sets:

@PhpCsFixer: Using the @PhpCsFixer rule set will enable the binary_operator_spaces rule with the default config.
@Symfony: Using the @Symfony rule set will enable the binary_operator_spaces rule with the default config.
