在PHP中,可以使用反斜杠(\)來(lái)轉(zhuǎn)義特殊字符。以下是一些常見(jiàn)的轉(zhuǎn)義字符的示例:

  1. 轉(zhuǎn)義雙引號(hào)("):
$str = "This is a \"quoted\" string.";
echo $str;  // 輸出:This is a "quoted" string.
  1. 轉(zhuǎn)義單引號(hào)('):
$str = 'This is a \'quoted\' string.';
echo $str;  // 輸出:This is a 'quoted' string.
  1. 轉(zhuǎn)義反斜杠(\):
$str = "This is a \\ backslash.";
echo $str;  // 輸出:This is a \ backslash.
  1. 轉(zhuǎn)義換行符(\n):
$str = "This is a line of text.\nThis is a new line.";
echo $str;  // 輸出:
// This is a line of text.
// This is a new line.
  1. 轉(zhuǎn)義制表符(\t):
$str = "This is a tabbed\ttext.";
echo $str;  // 輸出:This is a tabbed    text.

需要注意的是,在使用某些特殊字符時(shí),還需要考慮字符串的引號(hào)使用,避免引號(hào)的沖突。
