我正在处理地址 但我只是想删除 街道号码,eg
123 假 St
我使用以下正则表达式 /[a-z]/i
,该表达式运作良好,结果
fake St
(编码)
然而,有时我也有这样的地址,例如:
M4 西部分配器 Fwy
我该如何保留M4部分?
M 西部分配器 Fwy
任何帮助都会感激不尽 欢呼

尝试
/^[0-9 ]+(?=[^d]+)/i
这与除数字以外的数字匹配, 测试 :
$subject = 123 Fake St ;
var_dump(preg_replace( /^[0-9 ]+(?=[^d]+)/i , , $subject));
$subject = M4 Western Distributor Fwy ;
var_dump(preg_replace( /^[0-9 ]+(?=[^d]+)/i , , $subject));
产出:
string(7) "Fake St"
string(26) "M4 Western Distributor Fwy"
使用使用
/[^a-z ]+/i
这将匹配任何一个或多个非字母的出现, 这些非字母被一个单词边界所捆绑。 实际上, 如果您只想删除数字, 您应该使用
/[d]+/
有时非正因方法也值得考虑
$test="123 Fake St";
$arr=explode(" ",$test);
if(ctype_digit($arr[0])){
$test=str_replace($arr[0],"",$test);
}
echo $test;
