Introduction to String function PHP(part 2)

Assalamu'alaikum and selamat sejahtera

Here is the example of the string function in PHP.

str_replace()

$text = "The string function";
$THEwordTHATyouWANTtoCHANGEit = "string";
$REPLACEthatWORDwithTHIS = "strong";
print $text . "<BR>";
$text = str_replace($THEwordTHATyouWANTtoCHANGEit,
$REPLACEthatWORDwithTHIS , $text);

print $text;

str_word_count()

$number_words = str_word_count("how many word?");

print $number_words;

strlen()

$length_of_string = strlen("This is how to count the length of string");

-note:it count the character and the space in the string.

substr()

$username = "my name is dotcom";
$check = substr($username, strlen($username) - 6);

if ($check == "dotcom" ) {
print "ends in dotcom";
}
else {
print "doesn't end in dotcom";

-note:strlen($username)-6 :PHP will take six character because we put(-6), if -4 then it take 4 character that behind this string.So,our string is this :my name is dotcom,then PHP will start to count at red,bold 'm' as one until six.So sixth charatcer is:d . Then,$check is equal to 'dotcom'.
