A single-line comment only comments to the end of the line or the current PHP code block, depending on which first appears. This means that in//...? > or # ...? The HTML code after > will be displayed:?> jump out of PHP mode and return to HTML mode,//or # does not affect this. If the asp_tags configuration option is enabled, the behavior is the same as//%> or #%>. However, the tag does not jump out of PHP mode in a single-line comment.
Problem:
1. What is the meaning of this sentence?
Reply to discussion (solution)
This was an
example
"#" only commented out "?>" before the PHP section, HTML "example" is not affected by the "#" comment.
Output
This was an example
"//" Same as "#"
With the asp_tags configuration option enabled,%> also applies to the above rules, i.e.
This is a ... # echo ' Simple ';%> example
Just comment out the part of PHP, the HTML behind "%>" is not affected by annotations.
