In php, you can use the file_get_contents () function to convert a file to a string.

The file_get_contents () function reads the contents of a file into a string. The syntax format of the function is as follows:

File_get_contents (file,include_path,context,start,maxlen)

The parameters are described as follows:

File: file to read

Include_path: optional parameter, which is used to set whether you want to search the file in include_path. Default is FALSE.

Context: optional parameter to represent a valid context resource created using the stream_context_create () function. If you do not need a custom context, you can use NULL to ignore it.

Start: an optional parameter that sets the location in the file where to start reading. Note that this parameter cannot be used on remote files

Maxlen: optional parameter, which is used to set the number of bytes to be read. The default is to read the entire contents of the file.

Note: when the file_get_contents () function fails, it may return a FALSE of type Boolean or a non-Boolean value (such as a null character). So you usually use the = = operator to test the return value of this function.
