PHP Oracle Chinese garbled problem
Usually when connecting to Oracle with the default configuration, you will encounter garbled characters when processing Chinese. In fact, most people know that before the client connects to the Oracle server, the character set information of the server must be correctly set on the client. Through PLSQL Run "select * from V$NLS_PARAMETERS;" to get the character set of oracle. The variable NLS_CHARACTERSET corresponds to the character set we need. For example, here is "WE8ISO8859P1"
The method of setting the character set is as follows:
Method 1: Set environment variables before connecting
putenv("NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1"); $conn=oci_new_connect($config['username'], $config['password'],$config['database']);
Related introduction:
Oracle General Oracle Company;
Oracle Corporation, the full name of Oracle Corporation (Oracle Software Systems Co., Ltd.), is the world's largest enterprise software company, headquartered in Redwood Beach, California, USA. Officially entered the Chinese market in 1989. In 2013, Oracle surpassed IBM and became the world's second largest software company after Microsoft.
Method 2: Set environment variables when connecting
$conn=oci_new_connect($config['username'], $config['password'],$config['database'],'we8iso8859p1');
But soon you will find that the Chinese data read through the above settings does not set the encoding It can be displayed normally, but once used in the page (if the character set of the page is UTF8), it will still be garbled.
And even if it is converted from we8iso8859p1 -> utf-8, it will still be garbled.
In fact, after careful study, I found that oci8 automatically converts the data to the default encoding format of the operating system after obtaining the data with the database encoding WE8ISO8859P1. If the default encoding of the operating system I use is GBK, it will actually be read through OCI8. , the character encoding is GBK, so when using the page, the encoding conversion should be from GBK -> utf-8:
echo iconv('GBK','utf-8',$vo["USERNAME"]);

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。
