PHP to remove the string hollow characters of common methods Summary, PHP string Hollow Summary

This paper summarizes the common methods of PHP to remove the characters of the string. Share to everyone for your reference. The specific analysis is as follows:

PHP contains four functions that can be used to remove a string space:

Trim () – Remove null characters at both ends of the string
LTrim () – Remove null characters from the front of the string
RTrim () – Remove null characters at the end of a string
Chop () – Same as RTrim ().

The code is as follows:

<?php$text = "\ t \ t jb51.net!\t \ t"; $leftTrimmed = LTrim ($text); $rightTrimmed = RTrim ($text); $bothTrimmed = Trim ($text );p rint ("lefttrimmed = ($leftTrimmed) \ n");p rint ("righttrimmed = ($rightTrimmed) \ n");p rint ("bothtrimmed = ($ bothtrimmed) \ n ");? >

Output Result:

lefttrimmed = (jb51.net!) righttrimmed = (jb51.net!) bothtrimmed = (jb51.net!)

I hope this article is helpful to everyone's PHP programming.
