Since I am still new to PHP, I am looking for a way to find out how to get a specific character from a string.
Example:
$word = "master";
$length = strlen($word);
$random = rand(1,$length);
So let's say the $random value is 3, then I would like to find out what character the third one is, so in this case the character "s". If $random was 2 I would like to know that it's a "a".
I am sure this is really easy, but I tried some substr ideas for nearly an hour now and it always fails.
Your help would be greatly appreciated.
charAt(int position) method of String Class can be used to get the character at specific position in a String. Return type of charAt(int position) is char. Index or position is counted from 0 to length-1 characters.
You can search for a particular letter in a string using the indexOf() method of the String class. This method which returns a position index of a word within the string if found. Otherwise it returns -1.
You can use substr()
to grab a portion of a string starting from a point and going length. so example would be:
substr('abcde', 1, 1); //returns b
In your case:
$word = "master";
$length = strlen($word) - 1;
$random = rand(0,$length);
echo substr($word, $random, 1);//echos single char at random pos
