Base::ezcBaseFeatures

Class ezcBaseFeatures

Provides methods needed to check for features.

Example:

<?php
echo "supports uid: " . ezcBaseFeatures::supportsUserId() . "\n";
echo "supports symlink: " . ezcBaseFeatures::supportsSymLink() . "\n";
echo "supports hardlink: " . ezcBaseFeatures::supportsLink() . "\n";
echo "has imagemagick identify: " . ezcBaseFeatures::hasImageIdentify() . "\n";
echo " identify path: " . ezcBaseFeatures::getImageIdentifyExecutable() . "\n";
echo "has imagemagick convert: " . ezcBaseFeatures::hasImageConvert() . "\n";
echo " convert path: " . ezcBaseFeatures::getImageConvertExecutable() . "\n";
echo "has gzip extension: " . ezcBaseFeatures::hasExtensionSupport( 'zlib' ) . "\n";
echo "has pdo_mysql 1.0.2: " . ezcBaseFeatures::hasExtensionSupport( 'pdo_mysql', '1.0.2' ) . "\n"
?>

Methods

classExists

static bool classExists( string $className , [bool $autoload = true] )

Returns if a given class exists.

Checks for a given class name and returns if this class exists or not. Catches the ezcBaseAutoloadException and returns false, if it was thrown.

Parameters:

Name	Type	Description
`$className`	string	The class to check for.
`$autoload`	bool	True to use __autoload(), otherwise false.

findExecutableInPath

static string findExecutableInPath( string $fileName )

Returns the path of the specified executable, if it can be found in the system's path.

It scans the PATH enviroment variable based on the OS to find the $fileName. For Windows, the path is with \, not /. If $fileName is not found, it returns null.

Parameters:

Name	Type	Description
`$fileName`	string

getImageConvertExecutable

static string getImageConvertExecutable( )

Returns the path to the ImageMagick convert utility.

On Linux, Unix,... it will return something like: /usr/bin/convert On Windows it will return something like: C:\Windows\System32\convert.exe

getImageIdentifyExecutable

static string getImageIdentifyExecutable( )

Returns the path to the ImageMagick identify utility.

On Linux, Unix,... it will return something like: /usr/bin/identify On Windows it will return something like: C:\Windows\System32\identify.exe

hasExtensionSupport

static bool hasExtensionSupport( string $extension , [string $version = null] )

Determines if the specified extension is loaded.

If $version is specified, the specified extension will be tested also against the version of the loaded extension.

Examples:

hasExtensionSupport( 'gzip' );

will return true if gzip extension is loaded.

hasExtensionSupport( 'pdo_mysql', '1.0.2' );

will return true if pdo_mysql extension is loaded and its version is at least 1.0.2.

Parameters:

Name	Type	Description
`$extension`	string
`$version`	string

hasFunction

static bool hasFunction( string $functionName )

Determines if the specified function is available.

Examples:

ezcBaseFeatures::hasFunction( 'imagepstext' );

will return true if support for Type 1 fonts is available with your GD extension.

Parameters:

Name	Type	Description
`$functionName`	string

hasImageConvert

static bool hasImageConvert( )

Determines if the ImageMagick convert utility is installed.

hasImageIdentify

static bool hasImageIdentify( )

Determines if the ImageMagick identify utility is installed.

os

static string os( )

Returns the operating system on which PHP is running.

This method returns a sanitized form of the OS name, example return values are "Windows", "Mac", "Linux" and "FreeBSD". In all other cases it returns the value of the internal PHP constant PHP_OS.

supportsLink

static bool supportsLink( )

Determines if hardlinks are supported.

supportsSymLink

static bool supportsSymLink( )

Determines if symlinks are supported.

supportsUserId

static bool supportsUserId( )

Determines if posix uids are supported.
