getInput(): Stream

Returns the input stream connected to the normal output of the subprocess. The stream obtains data piped from the standard output of the process represented by this Process object.

---

getOutput()

getOutput(): Stream

Returns the output stream connected to the normal input of the subprocess. Output to the stream is piped into the standard input of the process represented by this Process object.

---

getError()

getError(): Stream

Returns the input stream connected to the error output of the subprocess. The stream obtains data piped from the error output of the process represented by this Process object.

---

inheritIO()

inheritIO(): php\lang\Process

---

redirectOutputToFile()

redirectOutputToFile(mixed $file): php\lang\Process

---

redirectOutputToInherit()

redirectOutputToInherit(): php\lang\Process

---

redirectOutputToPipe()

redirectOutputToPipe(): php\lang\Process

---

redirectErrorToFile()

redirectErrorToFile(mixed $file): php\lang\Process

---

redirectErrorToInherit()

redirectErrorToInherit(): php\lang\Process

---

redirectErrorToPipe()

redirectErrorToPipe(): php\lang\Process

---

redirectInputFromFile()

redirectInputFromFile(mixed $file): php\lang\Process

---

redirectInputFromInherit()

redirectInputFromInherit(): php\lang\Process

---

redirectInputFromPipe()

redirectInputFromPipe(): php\lang\Process

---
