Question

我的文字标题是

This User "The Title Of The Post"

我想抓住INSIDE中的引号，并将其存储在变量中。我如何用正则表达式和php做到这一点？

Answer 1

http://www.php.net/preg_match

<?php
$x = 'This User "The Title Of The Post"';

preg_match('/".*?"/', $x, $matches);

print_r($matches);

/*
  Output:
  Array
  (
      [0] => "The Title Of The Post"
  )

*/
?>

Answer 2

<?php

$string = 'This User "The Title Of The Post"';

preg_match_all('/"([^"]+)"/', $string, $matches);

var_dump($matches);

Answer 3

$string = 'This user "The Title Of The Post"';

$its_a_match = preg_match('/"(.+?)"/', $string, $matches);
$whats_inside_the_quotes = $matches[1];

$its_a_match如果成功匹配则为1，否则为0。 $whats_inside_the_quotes将包含正则表达式中括号中匹配的字符串。

如果它有点不清楚（它是），preg_match()实际上给$matches（第三个参数）赋值。

Answer 4


$str = 'This User "The Title Of The Post"';
$matches = array();
preg_match('/^[^"]*"([^"]*)"$/', $str, $matches);
$title = $matches[1];
echo $title; // prints The Title Of The Post

使用regex / php读取引文内的文本
