Here you can see how to remove unnecessary whitespace and specific characters from the beginning and end of strings using PHP’s trim(), ltrim(), and rtrim() functions.
Code:
<?php
$stringTrim = " , Hello World \t , ";
$anothrerWord ="Great";
echo $stringTrim;
echo $anothrerWord;
echo '<br>After using Trimming function trim($stringTrim) :<br>';
echo trim($stringTrim);
echo $anothrerWord;
echo '<br>After using Trimming function trim($stringTrim, \' ,\') :<br>';
echo trim($stringTrim, ' ,');
echo $anothrerWord;
echo '<br>After using Trimming function ltrim($stringTrim, \' ,\') :<br>';
echo ltrim($stringTrim, ' ,');
echo $anothrerWord;
echo '<br>After using Trimming function rtrim($stringTrim, \' ,\') :<br>';
echo rtrim($stringTrim, ' ,');
echo $anothrerWord;
?>
Output
, Hello World , Great
After using Trimming function trim($stringTrim) :
, Hello World ,Great
After using Trimming function trim($stringTrim, ' ,') :
Hello World Great
After using Trimming function ltrim($stringTrim, ' ,') :
Hello World , Great
After using Trimming function rtrim($stringTrim, ' ,') :
, Hello World Great
