Methods
getAllRawData()
Returns the raw data of all installed.php which are currently loaded for custom implementations

array<string|int, array<string|int, mixed>>getInstalledPackages()
Returns a list of all package names which are present, either by being installed, replaced or provided
    public
            static        getInstalledPackages() : array<string|int, string>

Return values
array<string|int, string>getInstalledPackagesByType()
Returns a list of all package names with a specific type e.g. 'library'
    public
            static        getInstalledPackagesByType(string $type) : array<string|int, string>
    Parameters
- $type : string

Return values
array<string|int, string>getInstallPath()
    public
            static        getInstallPath(string $packageName) : string|null
    Parameters
- $packageName : string
Return values
string|null —If the package is being replaced or provided but is not really installed, null will be returned as install path. Packages of type metapackages also have a null install path.
getPrettyVersion()
    public
            static        getPrettyVersion(string $packageName) : string|null
    Parameters
- $packageName : string
Return values
string|null —If the package is being replaced or provided but is not really installed, null will be returned as version, use satisfies or getVersionRanges if you need to know if a given version is present
getRawData()
Returns the raw installed.php data for custom implementations
    public
            static        getRawData() : array<string|int, array<string|int, mixed>>
    Use getAllRawData() instead which returns all datasets for all autoloaders present in the process. getRawData only returns the first dataset loaded, which may not be what you expect.

Return values
array<string|int, array<string|int, mixed>>getReference()
    public
            static        getReference(string $packageName) : string|null
    Parameters
- $packageName : string
Return values
string|null —If the package is being replaced or provided but is not really installed, null will be returned as reference
getRootPackage()
    public
            static        getRootPackage() : array<string|int, mixed>
    Tags
Return values
array<string|int, mixed>getVersion()
    public
            static        getVersion(string $packageName) : string|null
    Parameters
- $packageName : string
Return values
string|null —If the package is being replaced or provided but is not really installed, null will be returned as version, use satisfies or getVersionRanges if you need to know if a given version is present
getVersionRanges()
Returns a version constraint representing all the range(s) which are installed for a given package
    public
            static        getVersionRanges(string $packageName) : string
    It is easier to use this via isInstalled() with the $constraint argument if you need to check whether a given version of a package is installed, and not just whether it exists
Parameters
- $packageName : string
Return values
string —Version constraint usable with composer/semver
isInstalled()
Checks whether the given package is installed
    public
            static        isInstalled(string $packageName[, bool $includeDevRequirements = true ]) : bool
    This also returns true if the package name is provided or replaced by another package
Parameters
- $packageName : string
- $includeDevRequirements : bool = true
Return values
boolreload()
Lets you reload the static array from another file
    public
            static        reload(array<string|int, array<string|int, mixed>> $data) : void
    This is only useful for complex integrations in which a project needs to use this class but then also needs to execute another project's autoloader in process, and wants to ensure both projects have access to their version of installed.php.
A typical case would be PHPUnit, where it would need to make sure it reads all
the data it needs from this class, then call reload() with
require $CWD/vendor/composer/installed.php (or similar) as input to make sure
the project in which it runs can then also use this class safely, without
interference between PHPUnit's dependencies and the project's dependencies.
Parameters
- $data : array<string|int, array<string|int, mixed>>
- 
                    A vendor/composer/installed.php data set

satisfies()
Checks whether the given package satisfies a version constraint
    public
            static        satisfies(VersionParser $parser, string $packageName, string|null $constraint) : bool
    e.g. If you want to know whether version 2.3+ of package foo/bar is installed, you would call:
Composer\InstalledVersions::satisfies(new VersionParser, 'foo/bar', '^2.3')
Parameters
- $parser : VersionParser
- 
                    Install composer/semver to have access to this class and functionality 
- $packageName : string
- $constraint : string|null
- 
                    A version constraint to check for, if you pass one you have to make sure composer/semver is required by your package 
Return values

            static        getInstalled() : array<string|int, array<string|int, mixed>>
