Question

我想在函数中str_replace。

尝试

str_replace(array('(', ')', array('"', '\'')), array('\(', '\)', '["|\']'), 'hello("test")');

所需的输出：

hello\(["|']test["|']\)

这可以，但是不是很有用：

str_replace(array('"', '\''), '["|\']', str_replace(array('(', ')'), array('\(', '\)'), 'hello("test")'));

如何解决此问题？

preg_replace

输出

$re = '/(.*)\("(.+)"\)/m';
$str = 'hello("test")';
$subst = "$1\([\"|']$2[\"|'\"]\)";

$result = preg_replace($re, $subst, $str);

echo $result;
