preg_replace php删除前导数字然后在句点后停止

Question

我有这个字符串。我想删除＆＃34; 0002。＆＃34;但它也删除了22.如何删除前导数字和点（。）然后停止删除任何数字？

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/[0-9]+./', '', $title );

输出：

Greatest Voices In The Business (Current Female Singers Only)

预期产出：

22 Greatest Voices In The Business (Current Female Singers Only)

Answer 1

那么，你需要删除从字符串开头到点的所有数字吗？ 使用^表示＆＃34;字符串开头＆＃34;

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/^[0-9]+\./', '', $title );

如果你需要删除任何数字后跟点，你的代码是正确的，除了点是特殊字符，需要转义。

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/[0-9]+\./', '', $title );
