/**
 * Uses the str_replace() method on a source string.
 *
 * @MigrateProcessPlugin(
 *   id = "str_replace"
 * )
 *
 * @codingStandardsIgnoreStart
 *
 * To do a simple hardcoded string replace, use the following:
 * @code
 * field_text:
 *   plugin: str_replace
 *   source: text
 *   search: foo
 *   replace: bar
 * @endcode
 * If the value of text is "vero eos et accusam et justo vero" in source, foo is
 * "et" in search and bar is "that" in replace, field_text will be "vero eos
 * that accusam that justo vero".
 *
 * Case insensitive searches can be achieved using the following:
 * @code
 * field_text:
 *   plugin: str_replace
 *   case_insensitive: true
 *   source: text
 *   search: foo
 *   replace: bar
 * @endcode
 * If the value of text is "VERO eos et accusam et justo vero" in source, foo is
 * "vero" in search and bar is "that" in replace, field_text will be "that eos
 * et accusam et justo that".
 *
 * Also regular expressions can be matched using:
 * @code
 * field_text:
 *   plugin: str_replace
 *   regex: true
 *   source: text
 *   search: foo
 *   replace: bar
 * @endcode
 * If the value of text is "vero eos et 123 accusam et justo 123 duo" in source,
 * foo is "/[0-9]{3}/" in search and bar is "the" in replace, field_text will be
 * "vero eos et the accusam et justo the duo".
 *
 * All the rules for
 * @link http://php.net/manual/function.str-replace.php str_replace @endlink
 * apply. This means that you can provide arrays as values.
 *
 * Multiple values can be matched like this:
 * @code
 * field_text:
 *   plugin: str_replace
 *   source: text
 *   search: ["AT", "CH", "DK"]
 *   replace: ["Austria", "Switzerland", "Denmark"]
 * @endcode
 *
 * @codingStandardsIgnoreEnd
