Obtaining method: 1. Use the basename() function, the syntax is "basename (file path, the suffix name that needs to be removed)"; 2. Use the pathinfo() function, the syntax is "pathinfo (file path, PATHINFO_FILENAME)" .

php is obtained without Methods for suffixed file names
1. Use the basename() function
The basename() function returns the file name part of the path. Syntax:
basename(path,suffix)
Parameter path: Indicates the path to be checked.
Parameter suffix: can be omitted, indicating the file extension. If the suffix parameter is not omitted, the file name without extension is output.
Example:
<?php $path = "/testweb/home.php"; //显示带有文件扩展名的文件名 echo basename($path); //显示不带有文件扩展名的文件名 echo basename($path,".php"); ?>
Output:
home.php home
2. Use the pathinfo() function
pathinfo () function returns information about the file path in the form of an array. Syntax:
pathinfo(path,options)
Parameter path: Indicates the path to be checked.
-
Parameter options: can be omitted, indicating the array elements to be returned, the default value is all. Can have the following values:
PATHINFO_DIRNAME: Only the directory name (dirname) is returned.
PATHINFO_BASENAME: Returns the complete file name (basename), that is, the file name with extension.
PATHINFO_EXTENSION: Returns only the extension (extension)
PATHINFO_FILENAME: Returns the file name (filename) without the extension.
Example:
<?php // 用文件名初始化变量 $file = 'demo.html'; // 仅提取文件名 $x = pathinfo($file, PATHINFO_FILENAME); // 输出 echo $x; ?>
Output:
demo

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。

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。

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。

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。

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。
