slice() method to remove the last 3 characters from a string, e.g. const withoutLast3 = str. slice(0, -3); . The slice method will return a new string that doesn't contain the last 3 characters of the original string.
The substr() and strpos() function is used to remove portion of string after certain character. strpos() function: This function is used to find the first occurrence position of a string inside another string. Function returns an integer value of position of first occurrence of string.
function clean($string) { $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens. return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars. }
Just do:
echo substr($string, 0, -3);
You don't need to use a strlen call, since, as noted in the substr documentation:
If length is given and is negative, then that many characters will be omitted from the end of string
<?php echo substr("abcabcabc", 0, -3); ?>
<?php echo substr($string, 0, strlen($string) - 3); ?>
