Implementation steps: 1. Use the fopen() function to open the text file, and use the fgets() function to read a line of text data, the syntax is "fgets(fopen("file path", "r"),1024) " will return a row of data of string type; 2. Use the explode() function to convert the read row of data into an array type, with the syntax "explode(' ', read row of data)".
The operating environment of this tutorial: windows7 system, PHP8.1 version, DELL G3 computer
In php, you can use fgets () and explode() functions to read a line of text data and convert it into an array.
fgets() function is used to read one row of data at a time, and the return value is a string type
explode() function is used Convert a line of data of string type to array type
#Implementation steps:
1. Use the fopen() function to open the text file. And use the fgets() function to read a line of text data
<?php header("Content-type:text/html;charset=utf-8"); $handle = @fopen("./test.txt", "r"); $info = fgets($handle,1024); var_dump($info); ?>
The data read is a string type and contains a newline character.
2. The explode() function converts the read row of data into an array type
<?php header("Content-type:text/html;charset=utf-8"); $handle = @fopen("./test.txt", "r"); $info = fgets($handle,1024); var_dump($info); $arr=explode(' ',$info); var_dump($arr); ?>

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”。

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。

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。

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。

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。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。
