示例1: wptexturize
/**
* Replaces common plain text characters into formatted entities
*
* As an example,
* <code>
* 'cause today's effort makes it worth tomorrow's "holiday"...
* </code>
* Becomes:
* <code>
* ’cause today’s effort makes it worth tomorrow’s “holiday”…
* </code>
* Code within certain html blocks are skipped.
*
* @since 0.71
* @uses $wp_cockneyreplace Array of formatted entities for certain common phrases
*
* @param string $text The text to be formatted
* @return string The string replaced with html entities
