-/**
- * This is a very simple filter based on string matching.
- *
- * <p>The filter admits two options {@link $stringToMatch} and
- * {@link $acceptOnMatch}. If there is a match (using {@link PHP_MANUAL#strpos}
- * between the value of the {@link $stringToMatch} option and the message
- * of the {@link LoggerLoggingEvent},
- * then the {@link decide()} method returns {@link LoggerFilter::ACCEPT} if
- * the <b>AcceptOnMatch</b> option value is true, if it is false then
- * {@link LoggerFilter::DENY} is returned. If there is no match, {@link LoggerFilter::NEUTRAL}
- * is returned.</p>
- *
- * <p>
- * An example for this filter:
- *
- * {@example ../../examples/php/filter_stringmatch.php 19}
- *
- * <p>
- * The corresponding XML file:
- *
- * {@example ../../examples/resources/filter_stringmatch.xml 18}
- *
