我正在寻找一个
PHP函数,可以修剪一个长字符串中的每一行.
例如:
<?PHP $txt = <<< HD This is text. This is text. This is text. HD; echo trimHereDoc($txt);
输出:
This is text. This is text. This is text.
是的,我知道trim()函数.只是不确定如何在像heredoc这样的长字符串上使用它.
function trimHereDoc($t) { return implode("\n",array_map('trim',explode("\n",$t))); }
