wp_remove_surrounding_empty_script_tags()
Removes leading and trailing _empty_ script tags.
This is a helper meant to be used for literal script tag construction within wp_get_inline_script_tag() wp_print_inline_script_tag(). It removes the literal values of "<script>" and "</script>" from around an inline script after trimming whitespace. Typically this is used in conjunction with output buffering, where ob_get_clean() is passed as the $contents argument.
Example:
// Strips exact literal empty SCRIPT tags. $js = '<script>sayHello();</script>; 'sayHello();' === wp_remove_surrounding_empty_script_tags( $js );
// Otherwise if anything is different it warns in the JS console. $js = '<script type="text/javascript">console.log( "hi" );</script>'; 'console.error( ... )' === wp_remove_surrounding_empty_script_tags( $js );
Внутренняя функция — эта функция рассчитана на использование самим ядром. Не рекомендуется использовать эту функцию в своем коде.
Хуков нет.
