如何从PHP中的字符串中删除电子邮件地址和电话号码？ [关闭]

I need to remove all email and phone number from string in PHP. Can someone help me on this?

This is just for a start up not a complete answer. You need to read more about regular expressions and its usage.

remove email addresses :

$pattern = "/[^@\s]*@[^@\s]*\.[^@\s]*/";
$replacement = "[removed]";
preg_replace($pattern, $replacement, $string);

Reference

For phone numbers :

$text = preg_replace('/\+?[0-9][0-9()-\s+]{4,20}[0-9]/', '[removed]', $text);

this looks for:

a plus symbol (optional), followed by a number, followed by between 4-20 numbers, brackets, dashes or spaces, followed by a number

and replaces with the string [removed].
