How do I return a character of a string at index $i?


Recommended Posts

Hi, I have a quick little baby question. I'm simply having difficulties searching for the answer.


I want to look at each character of a string.


This will work:

$var = "Joe";
echo strlen($var) ."<br />";
for($i = 0; $i < strlen($var); $i++)
echo $i. $var[$i] ."<br />";


It will print:




That is, believe it or not, exactly what I want to do. However, I don't think that is the proper way of doing it. Is there not a pre-built function designed to return a character of a string at index $i?


It has been my experience, that the way I am doing it above will either malfunction or will simply not work / won't compile.



Thanks for you help!
