In PHP, you can use the iconv() function to convert the data encoding from utf-8 to gbk. This function can convert the string according to the required character encoding. The syntax "iconv("UTF-8 ","gbk//TRANSLIT",$str)".
The operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer
In php, you can use iconv () function converts the encoding of data from utf-8 to gbk.
<?php header("Content-type:text/html;charset=UTF-8"); $str= '你好,这里是utf8转gbk!'; echo $str; echo '<br />'; echo iconv("UTF-8","gbk//TRANSLIT",$str); //将字符串的编码从UTF-8转到GB2312 ?>
iconv() function can also convert encoding gbk to utf8
<?php header("Content-type:text/html;charset=GB2312"); $str= '你好,这里是gbk转utf8!'; echo $str; echo '<br />'; echo iconv("GB2312","UTF-8",$str); //将字符串的编码从UTF-8转到GB2312 ?>
Description: iconv() function
iconv() function can convert a string according to the required character encoding.
Syntax:
iconv(string $in_charset, string $out_charset, string $str): string
Convert the string str from in_charset to out_charset.
Parameter description:
$in_charset: Input character set.
-
$out_charset: Output character set.
If you add the string //TRANSLIT after out_charset, the transliteration function will be enabled. This means that when a character cannot be represented by the target character set, it can be approximated by one or more similar characters. If you add the string //IGNORE, characters that cannot be expressed in the target character set will be silently discarded. Otherwise, an E_NOTICE is raised and false is returned.
WARNING
//TRANSLIT operation details are highly dependent on the system's iconv() implementation (see ICONV_IMPL). It is reported that the implementation on some systems will directly ignore //TRANSLIT, so the conversion may fail and out_charset will be unqualified.
#$str: The string to be converted.
Return value: Returns the converted string, or returns false on failure.
Starting from version 5.4.0, false will be returned when the character is illegal, unless //IGNORE is specified in the output character. In previous versions, it would return a partial string.

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。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
