不能反序列化字符串

Question

当我尝试对以下字符串进行反序列化时：

a:3:{i:0;s:19:\"Sales+%2F+Customers\";i:1;s:78:\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\";i:2;s:13:\"Manufacturing\";}

它返回false并且收到以下警告：

WARNING: Error at offset 9 of 158 bytes

它是通过在数组上调用serialize生成的，尽管对我来说看起来很有效，但我不明白问题是什么？

Answer 1

在这种情况下，斜杠无效，请使用stripslashes() 。 下面的演示代码：

<pre>
<?php
$x = "a:3{i:0;s:19:\"Sales+%2F+Customers\";i:1;s:78:\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\";i:2;s:13:\"Manufacturing\";}";

echo "unserializing $x: " . PHP_EOL;

try {
    print_r(unserialize($x));
    echo PHP_EOL;
} catch (\Exception $e) {
    echo $e->getMessage() . PHP_EOL;
}

$y = "a:3{i:0;s:19:\\\"Sales+%2F+Customers\\\";i:1;s:78:\\\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\\\";i:2;s:13:\\\"Manufacturing\\\";}";

echo "unserializing $y: " . PHP_EOL;

try{
    print_r(unserialize($y));
    echo PHP_EOL;
} catch (\Exception $e) {
    echo $e->getMessage() . PHP_EOL;
}

echo "unserializing stripslashes($y): " . PHP_EOL;

try{
    print_r(unserialize(stripslashes($y)));
} catch (\Exception $e) {
    echo $e->getMessage() . PHP_EOL;
}
?>
</pre>
