There is apex_util.string_to_table – see my answer to this question. Also, prior to the existence of the above function, I once posted a solution here on my blog. Update In later versions of APEX, apex_util.string_to_table is deprecated, and a similar function apex_string.split is preferred.
You can end up with invalid XML, but you will not find out until you parse it again – and then it is too late. I learned this the hard way.
By definition, isdecimal() ⊆ isdigit() ⊆ isnumeric(). That is, if a string is decimal, then it’ll also be digit and numeric. Therefore, given a string s and test it with those three methods, there’ll only be 4 types of results. +————-+———–+————-+———————————-+ | isdecimal() | isdigit() | isnumeric() | Example | +————-+———–+————-+———————————-+ | True | True … Read more
Attention: Please see Leo Dabus’ answer for a proper implementation for Swift 4 and Swift 5. Swift 4 or later The Substring type was introduced in Swift 4 to make substrings faster and more efficient by sharing storage with the original string, so that’s what the subscript functions should return. Try it out here extension … Read more
The idea behind email-injection is that attacker inject line feed (LF) in the email headers and so he adds as many headers as he wants. Stripping those line feeds will protect you from this attack. For detailed info check http://www.phpsecure.info/v2/article/MailHeadersInject.en.php The best practice is to rely on a well-written, frequently updated and widely-used code. For … Read more
It could be: function split2($string, $needle, $nth) { $max = strlen($string); $n = 0; for ($i=0; $i<$max; $i++) { if ($string[$i] == $needle) { $n++; if ($n >= $nth) { break; } } } $arr[] = substr($string, 0, $i); $arr[] = substr($string, $i+1, $max); return $arr; }
For this kind of thing, regexps are very useful : import re print(re.findall(‘\\blocal\\b’, “Hello, locally local test local.”)) // [‘local’, ‘local’] \b means word boundary, basically. Can be space, punctuation, etc. Edit for comment : print(re.sub(‘\\blocal\\b’, ‘*****’, “Hello, LOCAL locally local test local.”, flags=re.IGNORECASE)) // Hello, ***** locally ***** test *****. You can remove flags=re.IGNORECASE … Read more
I realized that the second way uses string concatenation and will create 5 new strings in memory and this might lead to a performance hit. No it won’t. Since these are string literals, they will be evaluated at compile time and only one string will be created. This is defined in the Java Language Specification … Read more
I would make it an array and use the sort function: $string = ‘bac’; $stringParts = str_split($string); sort($stringParts); echo implode($stringParts); // abc
Why can’t we write directly to this buffer? I’ll state the obvious point: because it’s const. And casting away a const value and then modifying that data is… rude. Now, why is it const? That goes back to the days when copy-on-write was considered a good idea, so std::basic_string had to allow implementations to support … Read more
