For each token, all sniffs that were executed on the token are displayed, along with the running time. -For example, the output above shows us that token 1, an if keyword, had 5 sniffs executed on it; the ControlSignature sniff, the MultiLineCondition sniff, the ScopeClosingBrace sniff, the ScopeIndent sniff and the InlineControlStructure sniff. Each was executed fairly quickly, but the slowest was the ControlSignature sniff, taking 0.0001 seconds to process that token. +For example, the output above shows us that token 2, an if keyword, had 4 sniffs executed on it; the ControlSignature sniff, the MultiLineCondition sniff, the ScopeClosingBrace sniff, and the InlineControlStructure sniff. Each was executed fairly quickly, but the slowest was the `ControlSignature` sniff, taking 0.0002 seconds to process that token. The other interesting piece of information we get from the output above is that some tokens didn't have any sniffs executed on them. This is normal behaviour for PHP_CodeSniffer as most sniffs listen for specific or rarely used tokens and then execute on it and a number of tokens following it. -For example, the ScopeIndentSniff executes on the if statement's token only, but actually checks the indentation of every line within the if statement. The sniff uses the scope map to find all tokens within the if statement. +For example, the `MultiLineConditionSniff` executes on the if statement's token only, but actually checks the format and indentation of every line within the if statement condition. The sniff uses the token map to find all tokens within the if condition.
