# PHP bindings for Go
|
|
|
|
This package implements bindings for calling PHP scripts and binding Go variables for use in PHP contexts.
|
|
|
|
## Building
|
|
|
|
Building this package requires that you have PHP built and installed as a library. For most Linux systems, this would be a file under `/usr/lib/libphp5.so`, and can usually be found in the `php5-embed` package, or variations thereof.
|
|
|
|
Once the PHP library is available, the bindings can be compiled with `go build` and are `go get`-able.
|
|
|
|
## Usage
|
|
|
|
Executing a script is very simple:
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"os"
|
|
php "github.com/deuill/go-php"
|
|
)
|
|
|
|
func main() {
|
|
engine, _ := php.New()
|
|
context, _ := php.NewContext(os.Stdout)
|
|
|
|
context.Exec("index.php")
|
|
}
|
|
```
|
|
|
|
The above will execute script file located in `index.php` and write any output to the `io.Writer` passed to `php.NewContext` (in this case, the standard output).
|
|
|
|
By executing the PHP context in a Goroutine, one can read from the writer as the output is generated by the script, and is useful for long-running scripts which output information during execution.
|
|
|
|
## Status
|
|
|
|
Currently, execution of script files as well as code snippets has been implemented, as well as binding of most base types from Go to PHP contexts.
|
|
|
|
Calling Go functions and creating classes from Go method receivers is currently a work in progress.
|
|
|
|
A test-suite is included, which covers most common uses of this library.
|
|
|
|
## Caveats
|
|
|
|
Be aware that, by default, PHP is *not* designed to be used in multithreaded environments (which severely restricts the use of these bindings with Goroutines) if not built with [ZTS support](https://secure.php.net/manual/en/pthreads.requirements.php).
|
|
|
|
Unfortunately, most distributions do not ship ZTS-enabled versions of PHP by default, and very few offer pre-compiled packages, so you're mostly left to compile one yourself. |
