Open Files In PHP
PHP fopen() function is used to open files or URLs and returns a resource. The fopen() function accepts two arguments: $filename and $mode. The $filename represents the file to be opened and $mode represents the file mode, for example, read-only, read-write, write-only, etc.
Syntax
fopen(filename,mode,include_path,context)
PHP Open File Mode
| Mode | Description |
|---|---|
| r | Opens file in read-only mode. It places the file pointer at the beginning of the file. |
| r+ | Opens file in read-write mode. It places the file pointer at the beginning of the file. |
| w | Opens file in write-only mode. It places the file pointer to the beginning of the file and truncates the file to zero length. If the file is not found, it creates a new file. |
| w+ | Opens file in read-write mode. It places the file pointer to the beginning of the file and truncates the file to zero length. If the file is not found, it creates a new file. |
| a | Opens file in write-only mode. It places the file pointer to the end of the file. If the file is not found, it creates a new file. |
| a+ | Opens file in read-write mode. It places the file pointer to the end of the file. If the file is not found, it creates a new file. |
| x | Creates and opens the file in write-only mode. It places the file pointer at the beginning of the file. If file is found, fopen() function returns FALSE. |
| x+ | It is same as x but it creates and opens file in read-write mode. |
| c | Opens file in write-only mode. If the file does not exist, it is created. If it exists, it is neither truncated (as opposed to 'w'), nor the call to this function fails (as is the case with 'x'). The file pointer is positioned on the beginning of the file |
| c+ | It is the same as c but it opens the file in read-write mode. |
