PHP learning considerations

: This article mainly introduces the accumulation of PHP learning precautions. if you are interested in the PHP Tutorial, please refer to it. 1. PHP tag

When learning php code, read files written by others, many of which are marked only by php. Without the end mark. It turns out that this is the recommended method in the php official manual.
If the file content is pure php code, it is best to delete the php end mark at the end of the file. This avoids accidental addition of spaces or line breaks after the php end mark, which may cause php to start outputting these spaces, but there is no intention to output them at this time. The following files:

'). AddClass ('pre-numbering '). hide (); $ (this ). addClass ('Has-numbering '). parent (). append ($ numbering); for (I = 1; I <= lines; I ++) {$ numbering. append ($ ('

'). Text (I) ;}; $ numbering. fadeIn (1700) ;}) ;}; script

The above describes the accumulation of PHP learning notes, including the content, and hope to be helpful to friends who are interested in PHP tutorials.
