Download the PHP
package dpolac/twig-only-once without Composer
On this page you can find all versions of the php package
dpolac/twig-only-once. It is possible to download/install
these versions without Composer. Possible dependencies are resolved
automatically.
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.
Extension provides two tests onlyOnce and onlyOnceWhenOccurs.
is onlyOnce
Test returns true only when it's called for the first time with given value and space pair.
Arguments
value: can be value of any type
number - is converted to string, so 12 and '12' are treated as same value,
string,
object - are compared by reference, so new \stdClass() and new \stdClass() are treated as different value,
array - to arrays are treated as same value when have exactly same key-value set; order of keys in hashes is ignored,
space: can be any string (default: 'default')
is onlyOnceWhenOccurs
Test returns true only when it's called for the n-th time with given value and space pair.
Note that onlyOnce is an alias to onlyOnceWhenOccurs(1), so they share internal occurrences' counter.

n: number of occurrences after which test returns true,
space: can be any string (default: 'default').
