[Introduction] PHP operator PHP has a rich set of operators, most of them directly from the C language. Depending on the function, operators can be divided into: arithmetic operators, string operators, assignment operators, bitwise operators,

Test instructions: Defines concatenate (1,n) =1234567......N. For example concatenate (1,13) = 12345678910111213. Given N and M, seek concatenate (1,n)%m. (1=Idea: Make F[n] represent concatenate (1,n). Then there are:f[i]=f[i-1]*10+ (i-1) +1

In PHP, there is only one string operator, and the collocated operator (.) is used to concatenate two string values together. To concatenate two variables, use this dot operator (.): Example: 1 with. And, is the same result; PHP is a
