This article mainly introduces some built-in php functions for operating arrays. 1. Merge arrays The array_merge () function combines arrays and returns a Union array. The obtained array starts with the first input array parameter and is immediately added according to the order in which the following array parameters appear. The format is: Copy codeThe code is as follows: Array array_merge (array array1 array2 ..., ArrayN) This function combines the units of one or more arrays. the values of

, help users find the list they want to buy faster and better. This concept, or the target, looks rather virtual, and we need to transform it into a technical goal that is easy to measure and implement. The final technical goal is to click on a single rate estimate to predict the probability of a user clicking or buying a purchase order. We will predict the click or the next single-rate high list in front, the more accurate the prediction, the user in the order of the list click, the more the or
