XMLWriter::writePi

xmlwriter_write_pi

(PHP 5 >= 5.1.2, PHP 7, PHP 8, PECL xmlwriter >= 0.1.0)

XMLWriter::writePi -- xmlwriter_write_pi — Writes a PI

面向对象风格

public XMLWriter::writePi(string $target, string $content): bool

过程化风格

xmlwriter_write_pi(XMLWriter $writer, string $target, string $content): bool

Writes a processing instruction.

xmlwriter: 仅用于过程调用。被修改的 XMLWriter 实例对象。此资源来自于对 xmlwriter_open_uri() 或 xmlwriter_open_memory() 的调用。
target: The target of the processing instruction.
content: The content of the processing instruction.

成功时返回 true，或者在失败时返回 false。

版本	说明
8.0.0	现在 `writer` 需要 XMLWriter 实例，之前需要的是 resource。
