正則表達式提取標籤

Question

我試圖用/在低於給定的數據一起提取字母之間的數據（我不想在多年的「s」和 - ）。

football soccer/basketball 

1990s-1999s 

我在preg_match_all函數中使用/\D[a-zA-Z].*/s。它返回字母和數字（當在rubular.com中進行測試時，上述表達式可以工作，但在PHP程序中不會）。

Answer 1

# ^([\D]+)$ 
# 
# Options: case insensitive;^and $ match at line breaks 
# 
# Assert position at the beginning of a line (at beginning of the string or after a line break character) «^» 
# Match the regular expression below and capture its match into backreference number 1 «([\D]+)» 
# Match a single character that is not a digit 0..9 «[\D]+» 
#  Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+» 
# Assert position at the end of a line (at the end of the string or before a line break character) «$» 

preg_match_all('/^([\D]+)$/im', $subject, $result, PREG_PATTERN_ORDER); 
$result = $result[0];
