This function is used to check for end-of-file on a file pointer and takes a filename as argument. It is basically used in loop to perform the same function on each line in a file. In PHP file writing process can be done with fwrite() function, which takes two parameters first file pointer and a string, with an optional length in bytes. The syntax of fwrite() function is: $fout=fwrite($fp,$fstring) įile close can be done using fclose(). The syntax of file close is:įclose() function does not require assignment in any variable. It is used to create and open a file only for writing purpose, if file exists this mode will return false and display an error. If file doesn’t exists it will simply create a file Read and append mode, if file exists the pointer will set at the end of file, otherwise a new file will be created. Write and read mode, if file exists contents will be overwritten otherwise a new file will be created.Īppend file, if file exists it will open and file pointer will set at the ending of file, if it doesn’t exists a new file will be created. Write mode only, if the file exists it will open otherwise a new file will be created. If the file already exists, earlier contents will be overwritten Read and write mode, file pointer will set at the starting of file. Read only mode, file pointer will set at the starting position of file. The function will return a file pointer if the file is successfully opened, otherwise it will return false (zero). In the above code, we have used two parameters while using fopen() function: In PHP before working with file, we must open the file first using fopen() functionįopen() function is used in the following manner to perform this task:, ) Using file handling we can open, create, upload and edit files. With PHP we can handle files easily. There are various in built functions available for file handling in PHP. In a file manipulation process following tasks can be included:
Web server can access only files located under root document, on the other side PHP can access a file from any location in the file system if the file permissions are set accurately or include_path is set correctly.
