PHP implements directory operations

This time I will bring you PHP to implement directory operations. What are the precautions for PHP to implement directory operations? The following is a practical case, let's take a look.

Recursively obtain directory content

Recursion point: when the file read is a directory.

1. First read the contents of a directory (excluding subdirectories):

2. Determine whether each read file is a directory , if it is a directory, call it recursively, passing the current subdirectory as a parameter.

#3. Indentation mode output result

The recursive call depth is the indentation level of the file determined by this function! Whenever a recursive call is made, the indentation level increases by 1 level.

//str_repeat: Repeat a string and return the result of input repeated multiplier times. string str_repeat (string $input, int $multiplier)

Returns the result of input repeated multiplier times.

4. Record the results in array mode
Format:

Array(    
Array(‘deep’=>0, ‘filename’=>’application’),    
Array(‘deep’=>1, ‘filename’=>’back‘),    
Array(‘deep’=>1, ‘filename’=>’controllers‘[, ‘type’=’dir’]))

Recursively delete directory contents
