我试图建立一个正则表达式，当它们之间有空格时，将数字连接在字符串中，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 cinema"
正则表达式可以是python语言也可以是php语言
谢谢!
使用前向查找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(我怀疑您可能想要):
$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
Python:
import re
text = 'abc 123 456 789 xyz'
text = re.sub(r'('d+)'s+(?='d)', r''1', text) # abc 123456789 xyz
此方法适用于任意数量的连续数字组，其中包含任意数量的间隔
