PHP comparison function Instance usage Summary

In PHP, there are many ways to compare strings, the first is to use the strcmp () function and the strcasecmp () function to compare bytes by Byte, and the second is to use the strnatcmp () function to compare the natural sort method, and the third is to use STRNCMP () The function specifies that the comparison begins at the location of the source string. Here are some further explanations for these methods. 1. String comparisons by Byte are two ways of comparing strings by Byte, using the strcmp () function and the strcasecmp () function, respectively. The difference between these two functions is that the strcmp () function distinguishes the case of characters, whereas the strcasecmp () function does not differentiate between the case of characters. Since these two functions are implemented basically the same way, here just take out the strcmp () function to do some introduction. The strcmp () function is used to compare two strings by byte. The syntax format is as follows: strcmp (string1, S
