finding last digit of a string?

[fix3r]

i need to find the last digit of a string.

 

for example

 

$pos = 1287120;

 

I need to check if the last digit is "0".

 

The number could be any length but I am positive it will be a number.

 

How would I do this?

Just cast the integer to a string and then get the last char the same way you would in any other string, there are various ways you can do this the easiest is probably using "[]" with strlen()

Sorry, maybe you misunderstood. I really have no clue how to actually get the last character of ANY string. That's what I am asking for. Thank you for responding though. Hopefully you understand my question more clearly now. That was my fault.

you can select individual characters using "[]"

 

$a = 'abc';

 

echo $a[0] //a

echo $a[1] //b

echo $a[2] //c

 

strlen($a)  // 3

 

echo $a[strlen($a) - 1] //c (the last character)

[chronister]

$pos = 1287120;

substr($pos, -1, 1);

will return a 0

substr('abcdef', -1, 1); //returns f

substr('1685484315', -1, 1); //returns 5

substr($str, -1) works, there is no need to specify the length
