Twig / PHP - Format string using Replace or Regex

Question

How can I format a string in Twig as follows:

For example: img = 05myphoto-Car.jpg

I need to remove the numeric prefix and -
I am mainly using this to output captions for images based on their filename

Desired Output:

Myphoto Car

I have tried this so far, from the docs:

{{ img |replace({'.jpg': "", '-' : " "}) }}

Outputs String

05myphoto Car

I also tried {{ replace({'range(0, 9)': ""}) }} // for numeric prefix - did not work

Answer 1

Better late than never...

Just register it (for me was on index.php )

$app['twig']->addFilter('preg_replace', new Twig_Filter_Function(function ($subject, $pattern, $replacement) {
    return preg_replace($pattern, $replacement, $subject);
}));

Then on the view: {{myVar|preg_replace('/\\\\d+/','')}}

Notice that all backslashes MUST be escaped, if not, they will be removed by Twig...

This works for me just fine (Craft CMS):

{# Removes all characters other than numbers and + #}
{{ profile.phone|replace('/[^0-9+]/', '') }}

Answer 3

如果您愿意在模板中执行此操作，尽管作为控制器/服务会更好，您可以启用preg_replace过滤器并使用preg_replace('/\\d+/','')类的内容去除数字并使用大写另外过滤。
