序列化字符串中的偏移量錯誤沒有意義

Question

因此，當我嘗試在PHP中對其進行序列化時，此字符串顯示為false。

我使用2個在線序列化網站。

第一次測試返回正常。 就是這個網站： http : //blog.tanist.co.uk/files/unserialize/

另一個網站顯示了真正的問題。 還是呢？ 我糊塗了。 這是這個網站： https : //www.functions-online.com/unserialize.html

我得到的第一個錯誤是“ 7441個字節的偏移量1095 ”，恰好是s:6:"filter";中的“ t s:6:"filter"; （位於摘要中的第12行）

我認為這意味着出於某種原因它將字符計數讀取為4？ 我嘗試替換所有字符，包括引號以確保它們不是代表多個字節的字符的某些奇怪版本。 那沒用。 但是，如果我將“過濾器”更改為“過濾器”，它就可以工作。 然后移至下一個偏移誤差。

在序列化之前，我已經在字符串上嘗試了許多轉換，這些是我在網上找到的解決方案。

utf8_encode

base64_decode

他們都沒有幫助。

這是字符串。 （直接從帶有utf8_general_ci排序規則的mysql表中復制）

Answer 1

Error at offset 1095 of 7441 bytes實際上是正確的。 但這並不完全意味着您的意思。

從偏移量62開始。在這里觀察到s:1025:"始於以偏移量70開始的字符串，並且據稱長度為1025，這意味着該字符串的結尾引號應為偏移量1095（70 + 1025）...但事實並非如此。

錯誤是在“偏移量” 1095處，因為唯一可能的有效值是" ... " ，而不是在那里找到的值。它實際上早於偏移量1084處的11個字節。因此，該錯誤是正確的，盡管乍一看有點違反直覺。

這是-11個字節的錯誤，奇怪/方便/不太奇怪，您會發現字符串中有11個換行符，這恰好解釋了如果\\r\\n僅用\\r替換的差異或僅\\n可能仍會正確顯示但不正確。

這樣做是如何的，您需要回溯調查，但是錯誤是正確的。 您有一個已序列化的值，該值已被破壞/損壞/操作不當，無法再解碼。
