+# evil-php
+什么？PHP环境运行太过稳定，无事可做？千篇一律的日常开发毫无挑战？想体验不知何时发生未知BUG的恐惧？
+
+把本项目引入你们的项目吧，你们的项目会有但不仅限于如下的神奇效果：
+
+* `var_dump` 在周末时，会有10%的概率返回`NULL`。
+* `in_array` 当数组长度可以被7整除时，永远返回`false`。
+* `array_map` 在周日时，方法的结果总是会丢失最后一个元素。
+* `array_filter` 返回值有50%的概率丢失最后一个元素。
+* `sleep` 总是会比预期时间慢1秒才触发。
+* `strtotime` 的结果总是会慢7分钟。
+* `json_encode` 会把I(大写字母I)变成l(小写字母L)。
+* `substr` 有50%几率返回空字符串。
+* `mb_strlen` 有50%几率返回0。
+* ...
+
+## Install
+### Make Install evil-php
+```sh
+$ /path/to/phpize
+$ ./configure --with-php-config=/path/to/php-config
+$ make && make install
+```
+### evil.ini
+```conf
+[evil]
+extension=evil.so
+```
+### example
+```php
+<?php
+
+var_dump(mb_strlen("123"));
+
+var_dump(substr("abc", 0, 1));
+
+var_dump(json_encode(["a" => "III", "I" => 2]));
+
+var_dump(strtotime("2023-1-1"));
+
+var_dump(in_array(1, [1, 2, 3, 4, 5, 6, 7, 10, 11, 12, "qwe" => "123"]));
+
+var_dump(in_array(1, [1, 2, 3, 4, 5, 6, 7]));
+
+var_dump(array_map(function ($v1, $v2) {
+    return $v1 + $v2;
+}, [1, 2, 3, 4], [1, 2, 3, 4]));
+
+var_dump(array_filter([1, 2, 3, 4, 5, 6, 7, 10, 11, 12, "qwe" => "123"], function ($v) {
+    return $v > 10 || is_string($v);
+}));
+
+function user_sleep()
+{
+    for ($i = 0; $i < 2; $i++) {
+        sleep(1);
+        echo strtotime(date("Y:m:d H:i:s")) . PHP_EOL;
+    }
