Question

我想编写一行包含长字符串的代码，例如：

addError("This is a really really really really really really really long text");

但是我想将文本分成多行。如何通过这种方式抛开：

addError("This is a really really really really really really" .
       "really long text");

编辑：我需要这样它也不会做换行符。（忘记我之前说的SQL事件）

Answer 1

如果SQL语法突出显示是您的问题，您可以使用heredoc正确格式化它，并且仍然可以使IDE的语法突出显示正常工作：

$query = <<<EOD
select *
from foo
where bar
EOD;

do_query($query);

如果你不想换行，你现在的做法似乎是正确的。有了上述内容，您需要在之后删除换行符，例如str_replace("\n", " ", $str)。

试试这个： -

$t = 'This is a really really really really really really';
$t .= ' really really really really really really';
$t .= ' really really really really really really';
$t .= ' long string';
addError( $t );

Answer 3

假设您尝试将输出分解为行，可以使用str_split( $string, $chunk_length )。

这会将长文本拆分为具有固定长度的字符串数组。

$array_of_strings = str_split($str, 100);//100 represents the length of the chunk
foreach ($array_of_strings as $line) {
  echo $line . '<br>';
}

您也可以使用chunck_split();

希望这有帮助！
