[英]Replace space character with regular expression, php
I am using the function preg_replace('/[^0-9A-F]/', '', $string)
to accept only numbers and letters but at the moment is not filtering spaces, how can I include that into my reg expression? 我正在使用函数
preg_replace('/[^0-9A-F]/', '', $string)
仅接受数字和字母,但目前不过滤空格,如何将其包含在reg表达式中? thanks 谢谢
preg_replace('/[^0-9A-F ]/', '', $string)
附带说明,您只允许使用A到F的大写字母。如果要所有字母:
preg_replace('/[^0-9A-Z ]/i', '', $string)
preg_replace('/[^0-9A-F\x20]/', '', $string)
尝试
preg_replace('/[^0-9A-F]/',( )'', $string)
