Is there a simplified way to check each index of an string array?

Question

For Example I have this string

$string = "HelloWorld";

And I want to check if the first four letters is equal to "Hell"

if($string[0]=="H"&&$string[1]=="e"&&$string[2]=="l"&&$string[3]=="l");

Is there a better or simplified way of checking this? maybe $string[0-4] or something like that

Will it always be the first four letters or will there be a time where you would want to check if the word "hell" exists in the string? — hungrykoala

just use substring from start index from 0 and length is 4. then make an if comparison, or are you restricted from using functions? — Kevin

If you just want to get the first N characters of your string you can use substr

 i.e:
 $string = "HelloWorld";
 $rest   = substr($string , 0, 4);  // returns "Hell"

Or if you want to check if a word exists in the string you can also just use strpos

i.e
$string = "HelloWorld";
$pos = strpos($string , 'Hell'); //will return false if word is not found in string
