Question

大家好，我遇到了从特定字符串中爆炸 MwLAI_TXowc a的问题，我想通过以下youtube代码爆炸 MwLAI_TXowc 。

<iframe width="640" height="360" src="https://www.youtube.com/embed/MwLAI_TXowc" frameborder="0" allowfullscreen=""></iframe>

请帮助我如何从php中的youtube嵌入代码中爆炸 MwLAI_TXowc 。提前致谢

Answer 1

您不必为此PHP函数使用PHP函数explode pathinfo更容易。

<?php

$url = 'https://www.youtube.com/embed/MwLAI_TXowc';
$basename = pathinfo($url)['basename'];

echo '<pre>';
var_dump($basename);
echo '<pre>';

?>

输出

string(11) "MwLAI_TXowc"

或者，如果您的PHP不支持使用函数进行直接数组访问

<?php 

$url = 'https://www.youtube.com/embed/MwLAI_TXowc';
$pathinfo = pathinfo($url);
$basename = $pathinfo['basename'];

echo '<pre>';
var_dump($basename);
echo '<pre>';

?>

输出

string(11) "MwLAI_TXowc"

Answer 2

将preg_match用于字符串

arr = Array.new(3)# { Array.new(3) }
sum = 0
for i in 0..2
  for j in 0..2
    print "[#{i},#{j}] = "
    arr[i]=Integer(gets)
    sum+=arr[i,j]#Error here: in `+': Array can't be coerced into Fixnum (TypeError)
  end
end
puts "sum = #{sum}"
