FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Backward Incompatible Changes in PHP 7

See PHP 7 UPGRADING

Implemented

Will not be implemented (including reason)

Not yet implemented

Indirect variable, property and method references are now interpreted with left-to-right semantics.
The global keyword now only accepts simple variables
Parentheses around variables or function calls no longer have any influence on behavior
Array elements or object properties that are automatically created during by-reference assignments will now result in a different order
list() will no longer assign variables in reverse order
Empty list() assignments are no longer allowed
list() no longer supports unpacking strings
Iteration with foreach() no longer has any effect on the internal array pointer
When iterating arrays by-value, foreach will now always operate on a copy of the array, as such changes to the array during iteration will not influence iteration behavior
When iterating arrays by-reference, modifications to the array will continue to influence the iteration.
Iteration of plain (non-Traversable) objects by-value or by-reference will behave like by-reference iteration of arrays
It is no longer possible to define two function parameters with the same name.
The func_get_arg() and func_get_args() functions will no longer return the original value that was passed to a parameter and will instead provide the current value (which might have been modified).
Exception backtraces will no longer display the original value that was passed to a function and show the modified value instead
Invalid octal literals (containing digits larger than 7) now produce compile errors.
Bitwise shifts by negative numbers will now throw a warning and return false
Left bitwise shifts by a number of bits beyond the bit width of an integer will always result in 0
Right bitwise shifts by a number of bits beyond the bit width of an integer will always result in 0 or -1 (depending on sign)
Strings that contain hexadecimal numbers are no longer considered to be numeric and don't receive special treatment anymore.
Due to the addition of the Unicode Codepoint Escape Syntax for double-quoted strings and heredocs, "\u{" followed by an invalid sequence will now result in an error
There are now two exception classes: Exception and Error. Both classes implement a new interface Throwable.
Some fatal errors and recoverable fatal errors now throw an Error instead
Parser errors now generate a ParseError that extends Error
Constructors of internal classes will now always throw an exception on failure
The error level of some E_STRICT notices has been changed
Removed support for static calls to non-static calls form an incompatible $this context.
It is no longer possible to use the following class, interface and trait names (case-insensitive): bool, int, float, string, null, false, true
The following class, interface and trait names are now reserved for future use, but do not yet throw an error when used: resource, object, mixed, numeric
The yield language construct no longer requires parentheses when used in an expression context
Removed ASP (<%) and script (
