Reading from a file

Reading from a file

PHP has several functions to read from a file. One common way is to use the fopen() function to open a file and then use the fgets() function to read lines from the file one by one. Another way is to use the file() function, which reads the entire file into an array where each element of the array represents a line of the file. Additionally, PHP provides functions like file_get_contents() to read the entire contents of a file into a string variable. You can also use fread() to read a specific number of bytes from a file or fgetc() to read a single character at a time. It’s important to note that you need to have appropriate file permissions to be able to read from a file.
