$ Newarr = array_merge ($ arr_a, $ arr_ B );
Shuffle ($ newarr); // shuffling (disrupt the array), with different results each time
Print_r ($ newarr); // split the array
$ Oldarr = array ("watermelon", "Apple", "grapefruit", "banana", "Mango", "Kiwi", "Hawthorn ");
$ Newarr = array_slice ($ oldarr, 2,-2); // remove the first two and the last two
Print_r ($ newarr); // New array
Print_r ($ oldarr); // All original arrays // join arrays
therefore much faster (1000 times times faster than pickle). You can use either of them, and we'll use the Cpickle module here. Remember, we call these two modules short as pickle modules.Examples of storage and storage are as follows:
Python code
Import Cpickle as P shoplistfile = ' Shoplist.data ' shoplist = [' Apple ', ' mango ', ' carrot '] f = File (shoplistf Ile, ' W ') p.dump (Shoplist, F) F.close () del shoplist f = file (shoplistfil
PHP is used to connect to the mongodb database. I use PHP to connect to the mango database, and I can also create a database, that is, I cannot insert data. The operations of the mango database on the SHELL client are normal. The following is the test code.
"MongoDB", "type" => "database", "count" => 1, "info" => (object) array ("x" => 203, "y" => 102), "versions" => array ("0.9.7", "0.9.8", "0.9.9");
