escaping

问题 I need to fulfill a requirement to only accept values in the form of MM/DD/YYYY. From what I've read on: https://www.w3.org/TR/xmlschema11-2/#nt-dateRep Using <xs:simpleType name="DATE"> <xs:restriction base="xs:date"/> </xs:simpleType> Is not going to work as its regex apparently is not supporting this format. I have found and adjusted this format: ^(?:(?:(?:0?[13578]|1[02])(\/)31)\1|(?:(?:0?[1,3-9]|1[0-2])(\/)(?:29|30)\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:0?2(\/)29\3(?:(?:(?:1[6-9]|[2-9]\d)

问题 I'm doing this to all strings before inserting them: mysql_real_escape_string($_POST['position']); How do I remove the: \ after retriving them? So I don't end up with: \"Piza\" Also is this enough security or should I do something else? Thanks 回答1: use stripslashes() to get rid of the escape character. Escaping is great. In case the value is going to be integer , I would suggest you do it like: $value = (int) $_POST['some_int_field']; This would make sure you always end up with an integer

问题 I'm having issues with escaping characters (namely period) found in variables when using selectors in jQuery. I was going to type this all out, but it was just easier taking a screenshot of my console window in Chrome. It looks like the variables and the clear text versions match up. I expect $('#'+escName) to return the div, just like $('#jeffrey\\.lamb') returns a div. It does not. Why? 回答1: You have to think in terms of the individual parsers that will be examining your string values. The

问题 I need to replace double quotes with single so that something like this \\\\servername\\dir1\\subdir1\\ becomes \\servername\dir1\subdir1\ I tried this string dir = "\\\\servername\\dir1\\subdir1\\"; string s = dir.Replace(@"\\", @"\"); The result I get is \\servername\\dir1\\subdir1\\ Any ideas? 回答1: You don't need to replace anything here. The backslashes are escaped, that's why they are doubled. Just like \t represents a tabulator, \\ represents a single \ . You can see the full list of

问题 I should send Hi" to a Yahoo server, so in PHP I should place \ befor the " , but it will get bad JSON arguments. How should I do it? Place Hi" in JSON code without error? $message = "Hi\""; $postdata = '{ "message" : "'.$message.'" }'; 回答1: Use json_encode instead of hand-crafting JSON: $postdata = json_encode(array("message" => $message)); If you must handcraft your JSON, don't forget to add a backslash before a quotation mark: $message = "Hi\\\""; // or, more clearly ... $message = 'Hi\\"'

问题 I have this code <?php $a = "\\u0000"; $b = preg_quote($a); echo "<br />my own: ".$a; echo "<br />with preg_quote:". $b; ?> result is here How is possible that one \ character vanished from my $a variable? I think it's very begginer behavior/question but I'm really lost about these escape characters. Disclaimer: I'm not begginer in PHP 回答1: because \ escapes the next one, as every \ needs to be escaped. with a single \ it escapes the next character witch is u, but \u isn't a char code so it

问题 I've the following method which allows me to protect MySQL entities: public function Tick($string) { $string = explode('.', str_replace('`', '', $string)); foreach ($string as $key => $value) { if ($value != '*') { $string[$key] = '`' . trim($value) . '`'; } } return implode('.', $string); } This works fairly well for the use that I make of it. It protects database, table, field names and even the * operator, however now I also want it to protect function calls, ie: AVG(database.employees
