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

過(guò)程化風(fēng)格

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

Writes a processing instruction.

xmlwriter: 僅用于過(guò)程調用。被修改的 XMLWriter 實(shí)例對象。此資源來(lái)自于對 xmlwriter_open_uri() 或 xmlwriter_open_memory() 的調用。
target: The target of the processing instruction.
content: The content of the processing instruction.

成功時(shí)返回 true，或者在失敗時(shí)返回 false。

版本	說(shuō)明
8.0.0	現在 `writer` 需要 XMLWriter 實(shí)例，之前需要的是 resource。
