这里先判断存不存在str传参,存在的话先拿去is_valid函数过滤一下,这里is_valid函数的作用是检查一下str字符串里面有没有存在不可打印的字符。ord函数是打印第一个字符的ASCII码必须在32到125之间 然后进入反序列化,这里反序列化后生成一个序列化对象,但是不触发任何函数,然后进程结束,序列化对象销毁,触发__destruct...
$replace=''; // Processes \r\n's first so they aren't converted twice. $newstr=str_replace($order,$replace,$str); //6==> /* 这个是需要注意的,参数 search 和 replace 均为数组,第一次先替换 'a' ,结果为 'apple p',第二次接着替换 'p',因此会出现结果 'apearpearle pear' */ //...
正则替换的函数原型:resultafterreplace=pregreplace(resultafterreplace=pregreplace(pattern, $replacement,string[,[string[,[limit=-1] [, $replaceCount]]) 跟 str_replace有些类似. 同样的 也可以 处理 数组,pattern和pattern和replace 都可以是数组, 替换法则也是一样, 只是多了一个limit参数.而且在数组的正...
This brings finer differentiation in the error logs in contrary to the previous approach where all the errors are logged with the notice level only. 9.在不完整的对象上不再调用析构方法 析构方法在一个不完整的对象(例如在构造方法中抛出一个异常)上将不再会被调用 10.call_user_func()不再支持对传...
You can do so either using an inline custom message array or by adding an entry in the validation language file. This message should be placed in the first level of the array, not within the custom array, which is only for attribute-specific error messages:...

Previously, it would return false if the same byte (for example, the first byte) of the input string was invalid in all candidate encodings. More generally, it would eliminate candidate encodings from consideration when an invalid byte was seen, and if the same input byte eliminated all ...
First, we set the encoding type for the column back to latin1, thereby removing the double encoding: e.g.: altertabletemptable modify temptable.ArtistNamevarchar(128)charactersetlatin1; Note: Be sure to use the correct field type for your table. In the example above, for our table, the ...
