The examples in this article summarize the common methods of removing hollow characters in strings in PHP. Share it with everyone for your reference. The specific analysis is as follows:
php contains four functions that can remove spaces from strings:
trim() – removes null characters from both ends of a string
ltrim() – removes null characters at the front of a string
rtrim() – removes 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); print("leftTrimmed = ($leftTrimmed)\n"); print("rightTrimmed = ($rightTrimmed)\n"); print("bothTrimmed = ($bothTrimmed)\n"); ?>
Output result:
leftTrimmed = (jb51.net! ) rightTrimmed = ( jb51.net!) bothTrimmed = (jb51.net!)
I hope this article will be helpful to everyone’s PHP programming design.
