1) path issues in HTML (TPL) template files

When an external file is introduced into a template file, the relative path used is relative

B. php file.

The template is only responsible for interpreting the variables in the placeholder {}<{}>

Testing by introducing images, CSS files, and JS files

2) location of the HTML (TPL) template file

All are relative

$ TPL-> template_dir = './TPL ';

3) Transfer the PHP file to different directories

Unique absolute path

Echo _ file __;

Echo $ _ server ['script _ filename'];

Difference between quotation marks in Regular Expressions

The PHP interpretation engine and the regular expression interpretation engine are separated.

\ S --- match any blank space;

$ Pattern = "// I ";

Echo "\ s"; --- explained by PHP --- \ s -- interpreted by the Regular Expression Engine \ s

Echo '\ s'; --- explained by PHP --- \ s -- interpreted by the Regular Expression Engine \ s

Note: Single and Double quotation marks

1) 'abc' "ABC" -------- same effect

2) '$ A \ B' "$ A \ B" ------- the effect of adding a variable is different.
