This article mainly introduces the method of PHP for string manipulation, the interested friend's reference, I hope to help you. In this paper, we describe a simple method for PHP to determine whether two strings are equal, and how to do this: Definition and usage The strcasecmp () function compares two strings. Tip: the strcasecmp () function is binary safe and is case-insensitive. Tip: This function is s
