Difference between fwrite and file_put_contents in PHP

The difference between fwrite and file_put_contents in PHP is the same: the file_put_contents () function writes a string to a file, just like calling the fopen (), fwrite (), and fclose () functions in turn.

Difference: using FILE_APPEND in the file_put_contents () function can avoid deleting the existing content in the file, that is, implementing the append function when writing multiple times to the same file.

For example:

Echo file_put_contents ("test.txt", "Hello World. Testing! ", FILE_APPEND );

File_put_contentswrite the strings into test.txt in the form of catch-up,

Fwrtie clears the previous records and only keeps the content currently written.

$ File = fopen ("test.txt", "w"); echo fwrite ($ file, "Hello World. Testing! "); Fclose ($ file );
