explode

Lets say I have: $line = "{This is my {sentence|words} I wrote.}" Output: This is my sentence I wrote. This is my words I wrote. But, the regex should match deep and nested values and split these values, for example: $line = "{This is my {sentence|words} I wrote on a {sunny|cold} day.}"; Output: This is my sentence I wrote on a sunny day. This is my sentence I wrote on a cold day. This is my words I wrote on a sunny day. This is my words I wrote on a cold day. My first though was doing it over explode as in code below, but the result was not appropriate: $res = explode("|", $line); Advices?

I´m having trouble exploding contents of a .txt file (structure below): 01Name 1 02whatever contents 03whatever contents ------------------- 01Name 2 02whatever contents 03whatever contents As you can see, the "delimiter" is "-------------------". Now, the question is: how to explode this file into an array, so I can search for a specific name and display that block´s contents? I´ve tried to explode like this: header("Content-type:text/plain"); $file = fopen("cc/cc.txt", "r"); while (!feof($file)) { $lot = fgets($file); $chunk = explode("-------------------",$lot); print_r($chunk); } fclose(

I have an NSString as follows: <img alt="996453912" src="http://d2gg0uigdtw9zz.cloudfront.net/large/996453912.jpg" /><a href="http://www.dealcatcher.com/shop4tech-coupons">Shop4Tech Coupons</a> I only need the first part (before the <a href part), and I cannot figure out how to remove the second part. I have tried a ton, but it has not worked. Use something like: NSRange rangeOfSubstring = [string rangeOfString:@"<a href"]; if(rangeOfSubstring.location == NSNotFound) { // error condition — the text '<a href' wasn't in 'string' } // return only that portion of 'string' up to where '<a href' was

Possible Duplicate: PHP syntax for dereferencing function result I have a string, which looks like 1234#5678 . Now I am calling this: $last = explode("#", "1234#5678")[1] Its not working, there is some syntax error...but where? What I expect is 5678 in $last . Is this not working in PHP? Array dereferencing is not possible in the current PHP versions (unfortunately). But you can use list [docs] to directly assign the array elements to variables: list($first, $last) = explode("#", "1234#5678"); UPDATE Since PHP 5.4 (released 01-Mar-2012) it supports array dereferencing . Most likely PHP is

本文讨论 Hive explode 关键字使用, 并使用一个简单案例来验证结果. Hive 支持 array 和 map 类型, 但是如何统计 array 或 map 里的值, 一直没有找到好的方法. Pig 有行转列关键字 flatten. 查阅了很多 Hive 资料, 找到了 explode 关键字. 谨以此例来验证 Hive explode 功能. hive> create table if not exists explode_array > ( > userId string, > userName string, > tags array<string> > ) > ROW FORMAT DELIMITED > FIELDS TERMINATED BY '\t' > COLLECTION ITEMS TERMINATED BY ','; OK Time taken: 0.942 seconds 数据样例: 00001 zhzhenqin 80,90 00002 hello java, 女 00003 world java,python,90 查询: hive> select * from explode_array limit 10; OK 00001 zhzhenqin ["80","90"] 00002 hello ["java"," 女"] 00003 world
