.
See more about the Laravel config helper function here.
env

helper function to Twig.
The example would output the value currently stored in APP_ENV
environment variable. Second parameter is default value, when ENV key does not exists.
session
Function move the functionality of the Laravel session()
helper function to Twig.
The example would output the value currently stored in my.session.key
.
See more about the Laravel session helper function here.
trans

strftime

The example would output Posted at 04.01.2016 22:57:42. See more format parameters.
uppercase
Make a string uppercase.

Strip whitespace (or other characters) from the beginning of a string.
The example would output Hello I'm jack without whitespaces from the start.

The example would output Hello I'm jack without whitespaces from the end.
str_repeat

The example would output You have 1 new mail or You have 3 new mails - depending on mails count.
truncate
Use the truncate filter to cut off a string after limit is reached.
The example would output Hello..., as ... is the default separator.
You can also tell truncate to preserve whole words by setting the second parameter to true. If the last Word is on the the separator, truncate will print out the whole Word.
Here Hello World! would be printed.
If you want to change the separator, just set the third parameter to your desired separator.
This example would print Hello W??.
wordwrap
Use the wordwrap filter to split your text in lines with equal length.
This example would print:
The default separator is "\n", but you can easily change that by providing one:
This would result in:

Pad a string to a certain length with another string from both sides.
This would print:
str_replace
Replace all occurrences of the search string with the replacement string.
This would return:
strip_tags
Strip HTML and PHP tags from a string. In first parameter you can specify allowable tags.
This would return:
leftpad
Pad a string to a certain length with another string from left side.
This would print:
rightpad
Pad a string to a certain length with another string from right side.
This would print:
rtl
Reverse a string.
This would print:
shuffle
Shuffle an array.
or in foreach:
time_diff
Use the time_diff filter to render the difference between a date and now.
The example above will output a string like 4 seconds ago or in 1 month, depending on the filtered date.
Output is translatable. All translations are stored at /lang
folder in this plugin. If you want more locales, just copy them from this repository, replace %count%
with :count
and send it as pull reqest to this repository.
Arguments
- date: The date for calculate the difference from now. Can be a string or a DateTime instance.
- now: The date that should be used as now. Can be a string or a DateTime instance. Do not set this argument to use current date.
Translation
To get a translatable output, give a Symfony\Component\Translation\TranslatorInterface as constructor argument. The returned string is formatted as diff.ago.XXX or diff.in.XXX where XXX can be any valid unit: second, minute, hour, day, month, year.
localizeddate
Use the localizeddate filter to format dates into a localized string representating the date. Note that php5-intl extension/php7-intl extension has to be installed!
The localizeddate filter accepts strings (it must be in a format supported by the strtotime function), DateTime instances, or Unix timestamps.

- format: Optional pattern to use when formatting or parsing. Possible patterns are documented in the ICU user guide.
localizednumber
Use the localizednumber filter to format numbers into a localized string representating the number. Note that php5-intl extension has to be installed!
Internally, Twig uses the PHP NumberFormatter::create() function for the number.

- style: Optional date format (default: 'decimal'). Choose one of these formats:
- 'decimal': NumberFormatter::DECIMAL

- 'percent': NumberFormatter::PERCENT

- 'int32': NumberFormatter::TYPE_INT32
- 'int64': NumberFormatter::TYPE_INT64
- 'double': NumberFormatter::TYPE_DOUBLE
- 'currency': NumberFormatter::TYPE_CURRENCY
- locale: The locale used for the format. If NULL is given, Twig will use Locale::getDefault()
localizedcurrency
Use the localizedcurrency filter to format a currency value into a localized string. Note that php5-intl extension has to be installed!
Arguments

mailto
Filter for rendering email as normal mailto link, but with encryption against bots!
returns
which will be rendered to page as normal
PHP encrypts your email address and generates the JavaScript that decrypts it. Most bots can't execute JavaScript and that is what makes this work. A visitors of your web page will not notice that you used this script as long as they has JavaScript enabled. The visitors will see "[javascript protected email address]" instead of the email address if they has JavaScript disabled.
Filter parameters
- first boolean parameter = returns email clickable (with link)
- second boolean parameter = encryption is enabled
- third string parameter = link text (not encrypted!)
- fourth (optional) parameter = CSS class name (will render <a mailto:.. class="my-class">..)
var_dump
Dumps information about a variable.
revision
Force the browser to reload cached modified/updated asset files. You can provide a format parameter so that the prepended timestamp get converted accordingly to the PHP date() function.
