php怎么读取字符串后几个字符Apr 22, 2022 pm 08:31 PM在php中，可以使用substr()函数来读取字符串后几个字符，只需要将该函数的第二个参数设置为负值，第三个参数省略即可；语法为“substr(字符串,-n)”，表示读取从字符串结尾处向前数第n个字符开始，直到字符串结尾的全部字符。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
