$clean_string = preg_replace("need this here remove date regex syntax", "", $string);

need a reg ex or a small code. See the sample code above.. remove date at the beginning of the text.. not the same as changing the text and dates. I do not date as in the example at the beginning of some text. Thank you in advance to help friends

这应该足以满足您的示例中显示的日期格式：

$result = preg_replace(
    '/^      # Start of string
    \d{1,2}  # 1-2 digits
    \s+      # whitespace
    [a-z]+   # 1 or more ASCII letters
    \s+      # whitespace
    \d{2,4}  # 2-4 digits
    \s*      # optional whitespace/ix', 
    '', $subject);
