![]() $newValue = urlencode ( (string) $oldValue ) I got around the problem by using a cast. If you try to urlencode a simplexml object, the script tanks. URL ENCODE FOR COLON FULLSo, it is more "standardised" than his suggestion of using a + sign, and more readable (and search engine indexable) than a full double encode/decode.īe careful when encoding strings that came from simplexml in PHP 5. This is effectively a double urlencode for slashes and single urlencode for everything else. Return str_replace ("%2f","/", urldecode ( $TheVal)) Return urlencode ( str_replace ("/","%2f", $TheVal)) You can also use rawurlencode () here, and skip the functions provided in this note.įor handling slashes in redirections, (see comment from cameron at enprises dot com), try this : I applaud the W3C's recommendation to use semicolons (' ') instead of the ampersands, but it doesn't really change the fact that you still need to HTML-escape the value of all your HTML tag attributes. script?variable1=value1&variable2=value2 This is false the W3C page linked to from here clarifies that the ampersands must ALWAYS be escaped. The information on this page is misleading in that you might think the ampersand (&) will only need to be escaped as & when there is ambiguity with an existing character entity. PS: If you try copy /pasting one of these characters to a TXT file, it will translate to a ?. The point? Be careful with decorative characters. It will display properly, but only when you don't convert entities. Firefox, however, does something weirder: it will convert it to it's HTML entity. ![]() If you try to pass one in Internet Explorer, IE will *disable* the submit button. However, some weird things happen when dealing with characters like (these are HTML entities): ‼ ▐ ┐ and Θ have weird things going on. Ones like о and З were passed correctly and were in their raw form when I passed them through without any filtering. I was testing my input sanitation with some strange character entities. This function supports n-dimensional arrays (it encodes recursively). Return implode ( $separator, $toImplode ) It handles properly POST/GET array vars.įunction _HTTPRequestToString( $arr_request, $var_name, $separator='&') ]=". I rewrote inus at flowingcreativity dot net function to generate an encoded url string from the POST, or GET array. ![]() $querystring= substr ( $querystring,0, strlen ( $querystring)-1) * $params The parameters to be converted into URL with key as name. * Makes an valid html request url by parsing the params array This very simple function makes an valid parameters part of an URL, to me it looks like several of the other versions here are decoding wrongly as they do not convert & seperating the variables into &. User Contributed Notes Roamy: info AT roamy DOT de See also urldecode(), htmlentities(), rawurldecode() and rawurlencode(). urlencode() and htmlentities() example ' Leave it as &, but simply encode your URLs using htmlentities() or htmlspecialchars(). You don't need to change PHP's arg_separator for this. URL ENCODE FOR COLON PORTABLEA more portable way around this is to use & instead of & as the separator. Unfortunately most user agents do not send form data in this semi-colon separated format. PHP supports changing the argument separator to the W3C-suggested semi-colon through the arg_separator. This is an obvious hassle that the W3C has been telling people about for years. Things like &, © and £ are parsed by the browser and the actual entity is used instead of the desired variable name. Note: Be careful about variables that may match HTML entities. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-This function is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page: ![]() URL ENCODE FOR COLON PLUShave been replaced with a percent ( % ) sign followed by two hex digits and spaces encoded as plus ( + ) signs. Returns a string in which all non-alphanumeric characters except -_. (PHP 3, PHP 4, PHP 5) urlencode - URL-encodes string Descriptionstring urlencode ( string str )
