PHP uses built-in functions file_put_contents to write files and append content

This article mainly introduces PHP using built-in function file_put_contents write files and append content method, combined with instance form analysis File_put_contents function through the parameter set to write files and append content of the relevant skills, very simple and practical, A friend you need can refer to the following

This article explains how PHP uses built-in functions file_put_contents write files and append content. Share to everyone for your reference, as follows:

Write content in append form

When the flags parameter value is set to File_append, the new data is written in such a way that the content is appended to the contents of the existing file:

Copy the Code code as follows:

<?phpfile_put_contents ("Test.txt", "This is another something.", file_append);? >

The behavior of file_put_contents () is actually equal to calling fopen (), fwrite (), and fclose () functions in turn.

File_append: Writes data appended to the end of the file

Parameter description:

Parameters

Description

FileName to write the data to
Data to be written to. The type can be String,array (but not a multidimensional array), or a stream resource
Flags are optional, which specifies how to open/write files. Possible values: 1.file_use_include_path: Check the built-in path of the filename copy
2.file_append: Writes data appended to the end of the file
3.LOCK_EX: Lock the file
Context is optional, and context is a set of options through which you can modify text properties

PHP built-in function file_put_contents for writing files:

The simplest way to write a file_put_contents function is to use only two parameters, one for the file path and one for the content to be written, with the following syntax:

Copy the Code code as follows:

File_put_contents (Filepath,data)

If the file does not exist, the File_put_contents function automatically creates the file, and if the file already exists, the original file is rewritten .

You can use the File_put_contents function to create and write a new file, or to rewrite an existing file .
Here is an example of a PHP code that uses the File_put_contents function:

The PHP code example creates a file with a path of C:\blabla\filesys\one.txt, and the content of the file is one for all.

PHP built-in function file_put_contents for appending content:

If you want to append content to an existing file, you can also use the File_put_contents function, just add a parameter .

Copy the Code code as follows:

File_put_contents (Filepath,data,flags)
when the value of flags is file_append, it means that the content is appended to the existing file. That is: the third parameter, the flags implementation, appends the content to the file, and if no such parameter overwrites the previous data directly .

For example, we want to append content to the C:\blabla\filesys\one.txt file on the example above, we can write:


After executing the PHP file, we looked at the C:\blabla\filesys\one.txt file and found that the contents of the file increased and became:

One for all and for one

The file_put_contents function returns the bytes written to the file (number of bytes), and returns FALSE if an error occurs.
