hi,
The php functions i have learnt today are...
1.strlen(string or $variable) -- tells the length of the string.
$var = 'hello';
echo strlen($var);
o/p: 5
2. strrev(string or $variable) -- reverses the given string.
$var = 'hello';
echo strrev($var);
o/p: olleh
3. strtolower(string or $varible) -- makes the entire string into lower case.
$var = 'HEllO';
echo strtolower($var);
o/p: hello
4. strtolower(string or $varible) -- makes the entire string into upper case.
$var = 'hello';
echo strtoupper($var);
o/p: HELLO
5. ucfirst(string or $varible) -- makes the first character of the string into upper case.
$var = 'hello';
echo ucfirst($var);
o/p: Hello
6. ucwords(string or $varible) -- makes the first character of the string into upper case.
$var = 'hello there';
echo ucwords($var);
o/p: Hello There
7. explode(delimiter,str,limit(optional)) -- splits the given string on every delimiter.
$fullname = 'bullet paandi';
$name = explode(" ",$fullname);
echo "firstname = ".$name[0];
echo "lastname = ".$name[1];
o/p: firstname = vijay lastname = kumar
8. str_split(str,split_length(optional)) -- splits the given string accordind to split length.
$fullname = 'bullet paandi';
$name = str_split($fullname,3);
echo " ".$name[0];
echo " ",$name[1];
echo " ".$name[2];
echo " ".$name[3];
