symfony - PHP basename Twig 等价物

Question

Twig 中是否有与 PHP basename() 等效的函数？

就像是:

$file = basename($path, ".php");

Answer 1

使用 Twig，我们可以找到最后一个点 ( . ) 之后的字符串，并将其从字符串中删除以获得文件名(但如果有多个点，它将不起作用)。

{% set string = "file.php" %}
{{ string|replace({ ('.' ~ string|split('.')|last): '' }) }}
{# display "file" #}
{% set string = "file.html.twig" %}
{{ string|replace({ ('.' ~ string|split('.')|last): '' }) }}
{# display "file.html" and not "file" #}

解释:

{{ string|replace({     # declare an array for string replacement
    (                   # open the group (required by Twig to avoid concatenation with ":")
        '.'
        ~               # concatenate 
        string
            |split('.') # split string with the "." character, return an array
            |last       # get the last item in the array (the file extension)
    )                   # close the group
    : ''                # replace with "" = remove
}) }}
