PHP functions (substr,rtrim) to remove last character from a string
Labels:
PHP
<?php
$string="apple,ball,cat,";
echo substr($string, 0, -1);
echo "<br/>";
echo rtrim($string, ",");
?>
Output:
apple,ball,cat
apple,ball,cat
rtrim is not the same as substr. Difference is shown below
<?php
$string="apple,ball,cat,,";
echo rtrim($string, ",");
?>
Output:
apple,ball,cat
As seen from the above example rtrim trims all specified character from the end part of the string.
