导读:我正在尝试构建一个正则表达式,当它们之间有空格时,它们会在字符串中连接数字,例如: $string = "I want to go home 8890 7463 and then go to 58639 6312 the cinema" 正则表达式应该输出: "I want to go home 88907463 and then go to 586396312 the cine

使用前瞻来查看下一个块是否是一组数字并删除尾随空格.这样,它适用于任何数量的集合(我怀疑你可能想要):
$string = "I want to go home 8890 7463 41234 and then go to 58639 6312 the cinema"; $newstring = preg_replace("/b(d+)s+(?=d+b)/","$1",$string); // Note: Remove the b on both sides if you want any words with a number combined. // The b tokens ensure that only blocks with only numbers are merged. echo $newstring; // I want to go home 8890746341234 and then go to 586396312 the cinema (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
