What this article brings to you is about how PHP extracts the numbers in a string. PHP extract the number of strings in the method summary (with code), there is a certain reference value, the need for friends can refer to, I hope to help you. PHP extracts the first set of numbers in a string Other ways in which PHP extracts

4SumGiven an array S of n integers, is there elements a, B, C, and D in S such that A + B + c + d = target? Find all unique quadruplets in the array which gives the sum of target.Note:Elements in a quadruplet (a,b,c,d) must is in non-descending order. (ie, a≤b≤c≤d)The solution set must not contain duplicate quadruplets.For example, given array S = {1 0-1 0-2 2}, and target = 0.A Solution set is:(-1, 0, 0, 1)(-2,-1, 1, 2)(-2, 0, 0, 2)Idea: This problem and 3Sum is related to the problem, the prob

The graphic verification code is generated (numbers and English uppercase and lowercase) and submitted for verification. The verification code is case-sensitive. When I first came into contact, I felt very fun. Then I studied it myself and made a demo. Then I sorted it out. I can use it next time. It is case-sensitive and I can click it to switch. On the
