Php STRPO/stripos（具有严格比较）失败

我目前有以下strpos/stripos（两者都尝试过，不会改变结果），用于标记论坛帖子中的某些指针

if (stripos($row->message, (string)$commit) !== false) {
  // Do stuff
}

不过，在一些情况下，当haystack（$row->message）包含needle（$commit）时（使用cast是因为$commit可以是int），strpos/stripos返回false

例如：

$test = stripos($row->message, (string)$commit);

非工作场景的一个示例是：

// (string)$commit 
string(7) "818df50"
// $row->message
string(321) "Intro. Crashes as soon as the main menu is shown. Graphics are horribly broken, no fixes have been found as of yet. [attachment=194] Build Used: Pull Request #3333 (0.0.3-5929) -> RPCS3-v0.0.3-2017-08-27-818f50b Side note: States it can display at 1080p, yet it is boxed in 1080p. However, it is fine in 720p."
// $test (strpos/stripos) 
bool(false)

// (string)$commit
string(7) "2570911" 
// $row->message
string(219) "RPCS3 v0.0.3-3-2570911 Alpha The game doesn't even show its graphics window. [quote] ·F 0:00:34.138812 {PPU[0x1000000] Thread (main_thread) [0x0087c094]} MEM: Access violation writing location 0xcffff2d0 [/quote]" int(15) [2570911]
// $test (strpos/stripos)
int(15) [2570911]

工作场景的一个示例是：

// (string)$commit 
string(7) "818df50"
// $row->message
string(321) "Intro. Crashes as soon as the main menu is shown. Graphics are horribly broken, no fixes have been found as of yet. [attachment=194] Build Used: Pull Request #3333 (0.0.3-5929) -> RPCS3-v0.0.3-2017-08-27-818f50b Side note: States it can display at 1080p, yet it is boxed in 1080p. However, it is fine in 720p."
// $test (strpos/stripos) 
bool(false)

// (string)$commit
string(7) "2570911" 
// $row->message
string(219) "RPCS3 v0.0.3-3-2570911 Alpha The game doesn't even show its graphics window. [quote] ·F 0:00:34.138812 {PPU[0x1000000] Thread (main_thread) [0x0087c094]} MEM: Access violation writing location 0xcffff2d0 [/quote]" int(15) [2570911]
// $test (strpos/stripos)
int(15) [2570911]

我不知道我是否遗漏了一些非常明显的东西，我检查了几次，方法似乎是正确的

注意：我知道有几十种方法可以做到这一点，但在这个特定场景中，我需要这些字符串比较

提前感谢。

在您的示例中

// (string)$commit 
string(7) "818df50"
// $row->message
string(321) "Intro. Crashes as soon as the main menu is shown. Graphics are horribly broken, no fixes have been found as of yet. [attachment=194] Build Used: Pull Request #3333 (0.0.3-5929) -> RPCS3-v0.0.3-2017-08-27-818f50b Side note: States it can display at 1080p, yet it is boxed in 1080p. However, it is fine in 720p."
// $test (strpos/stripos) 
bool(false)

针

818df50

不包含在草堆中。干草堆包含一个非常接近的字符串（

818f50

），但这不是一个完全匹配的字符串

所以。。。它正在做正确的操作。

哦，哈哈，我需要多睡一会儿。检查了好几次，没有注意到这样一个愚蠢的错误。谢谢
