Syntax: String strtok (String arg1, String arg2)

Description:

Strtok () is used to cut the string, and that is if you have a string like "This was an example string", you can use a blank character as a token to cut the string apart and become an individual word.

Example:

<?php

$string = "This is a example string";

$tok = Strtok ($string, "");

while ($tok) {

echo "word= $tok <br>";

$tok = Strtok ("");

}

?>

Note: The string argument is used only the first time the Strtok () is called, and the call only needs to use the tag, just as it will record the current string. To cut another new string, you only need to call Strtok () and string parameters again. You can place a variety of tags in the tag parameters, and when you find the characters in any argument, the string is cut open.

Your mark may be equal to "0", which is equivalent to false in the conditional expression.
