strpos/stripos函数（严格的比较）未能

Question

我公司目前有以下strpos/stripos函数（都尝试，不改变结果），从论坛帖子用于标记某些针。

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

的东西大多是工作正常，然而，在少数情况下，当草垛（$按行>消息）包含针（$提交）（使用造型，因为$承诺可以是int）strpos/stripos函数的返回false 。

例如：

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

非工作情况下的一个例子是：

// (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) 

工作情况的一个例子是：

// (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] 

我不知道我是否错过了一些非常明显的东西，我检查了几次，方法似乎正确。

注：我知道有几十种方法可以做到这一点，但在这种特定情况下，我需要这些字符串比较。

在此先感谢。

在你的榜样......

// (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。干草堆包含非常接近的字符串（818f50），但这不完全匹配。

所以......它做了正确的操作。
