🧩 GetExtensions

Gets the list of all installed extension names in the current PHP environment.

When to use

Use it when you need to scan the set of available extensions, or to confirm that required extensions are present before installing dependencies.

Signature

func (c *Composer) GetExtensions() ([]string, error)

Parameters

Parameter	Type	Description
None	—	This method takes no parameters

Return value

• []string: list of installed PHP extension names (the Loaded extensions: header line and empty lines are filtered out)
• error: returned when command execution fails

Example

package main

import (
    "fmt"
    "log"

    "github.com/scagogogo/composer-skills/pkg/composer"
)

func main() {
    comp, err := composer.New(composer.DefaultOptions())
    if err != nil {
        log.Fatal(err)
    }

    extensions, err := comp.GetExtensions()
    if err != nil {
        log.Fatalf("failed to get PHP extensions: %v", err)
    }

    fmt.Println("Installed PHP extensions:")
    for _, ext := range extensions {
        fmt.Println("- " + ext)
    }
}

Advanced

• This method runs composer run --show-extensions and parses the output line by line
• To only check whether a single extension exists, use the lighter-weight HasExtension
• To check whether extensions satisfy the platform constraints in composer.json, use CheckPlatform
