 | 下面小结PHP中的几个字符函数， 小结一下： 1）ucfirst 将首字母变大写，比如 $string = "this is my web development blog"; echo ucfirst($string); // Output: This is my web development blog 2) lcfirst,将首字母变小写 $string = "This is my Web Development Blog"; echo lcfirst($string); // Output: this is my Web Development Blog 3）strtoupper,将整个字符串变大写 $string = "this is my web development blog"; echo strtoupper($string); // Output: THIS IS MY WEB DEVELOPMENT BLOG 4）strtoplower，将整个字符串变小写 $string = "tHiS is mY WeB DevElOpMenT bLoG"; echo strtolower($string); // Output: this is my web development blog 5）ucwords(),可以将句子中每个单词的第一个字母变大写，比如 $string = "this is my web development blog"; echo ucwords($string); // Output: This Is My Web Development Blog | |
