Answer 1

你应该尝试以下方式。

<?php 
$i = 0;
?>
@foreach($questions as $question)
 {{ $i++ }}
@endforeach

@foreach($inquiries as $question)
 {{ $i++ }}
@endforeach

@foreach($queries as $question)
 {{ $i++ }}
@endforeach

@foreach($examinations as $question)
 {{ $i++ }}
@endforeach

@foreach($inquisitions as $question)
 {{ $i++ }}
@endforeach

Answer 2

@php
  $i = 0;
@endphp
@foreach($questions as $question)
 {{ $i }}
  $i++;
@endforeach

在每个foreach循环中使用$ i作为增量$ i ++

Answer 3

如果希望你的$ i在每次循环后改变，你应该通过引用传递变量。检查以下链接中的文章： 链接：http://php.net/manual/en/language.references.pass.php

Answer 4

您可以使用专用于此的刀片变量：

@foreach($questions as $question)
    {{ $loop->iteration }}
@endforeach

@foreach($inquiries as $question)
    {{ $loop->iteration }}
@endforeach

@foreach($queries as $question)
    {{ $loop->iteration }}
@endforeach

@foreach($examinations as $question)
    {{ $loop->iteration }}
@endforeach

@foreach($inquisitions as $question)
    {{ $loop->iteration }}
@endforeach
