The Strtok () function can control the rhythm relative to explode (). Cut strings on demand. The advantages are:
1. You can define multiple separators at once. When the function is executed, it is cut by a single delimiter rather than by the entire delimiter, while the explode is cut by the entire separator string. As a result, explode can be cut in Chinese, and strtok is not, will be garbled.
2. When using the while or for mate Strtok () traversal, you can change the delimiter at any time, or you can break out of the cut at any time.
Example 1: Demo in Chinese +explode to cut
$string = "This is the PHP Forum Forum Panel Forum Column Forum H Admin Forum member";
$arr = explode ("forum", $string);
foreach ($arr as $v)
{
echo $v. "
";
}
echo "-------------
";
Return:
This is PHP
Section
Column
H Administrator
Member
-------------
Example 2: Demonstrate replacement of the cut, note that the "H" delimiter is no longer in the later while. And just use a space.
$string = "This is the PHP Forum Forum Panel Forum Column Forum H Admin Forum member";
$tok = Strtok ($string, "H"); Space +h
$n = 1;
while ($tok!== false) {
echo "$tok
";
$tok = Strtok (""); Space
if ($n >2) break; Can jump out at any time.
$n + +;
}
echo "-------------
";
Return:
This is P
P Forum
Forum section
Forum columns
Forum h Admin
Forum members
-------------
Example 3: Demonstrates multi-delimiter characters.
$string = "This istan examplenstring";
$tok = Strtok ($string, "NT"); #空格, line break, TAB
while ($tok!== false) {
echo "$tok
";
$tok = Strtok ("NT");
}
echo "-------------
";
Return:
This

An
Example
String
-------------
$string = "ABCDE 123c4 99sadbc99b5232";
$tok = Strtok ($string, "BC");
while ($tok! = "") {
echo "$tok
";
$tok = strtok ("BC");
}
echo "-------------
";
Return:
A
De 123
4 99sad
99
5232
-------------
Example 4: The demo uses for to traverse:
$line = "leontatkinsontleon@clearink.com";
for ($token = Strtok ($line, "T"); $token! = ""; $token =strtok ("T"))
{
Print ("token: $token
n ");
}
Return:
Token:leon
Token:atkinson
Token:leon@clearink.com
