substr_replace和substr得到最后一个char返回�

Question

I tried:

substr($string, 0, -1);
substr_replace($string ,"",-1);

but get always

�

and not the last char of my string????

I want to compare strings and the last Char of stringTwo always is missing, so i tried to find equal stings with substr_replace or substr function and deleting the last char.

$stringOne = "house";

$stringTwo = "hous";

it is strange again and again i get �� by using substring and substr_replace... with mb_substr i can delete the �, but how can i check before doing something if i use mb_substr or substr???

Answer 1

To get the last character of a string just use the substr method. The substr parameters are substr(string $string, int $start, [,int $length]).

This should get the last character:

echo substr($string, -1, 1);

To compare two strings, where the last character is removed from $stringTwo, you can use the following:

if($stringTwo == substr($stringOne, 0, -1)){}
