Summary of PHP string splitting function_PHP tutorial

There are many, many string splitting functions in PHP. Now I will introduce to you various examples of string splitting in PHP. Friends in need can refer to them for reference. ​

The basic syntax of PHP function split() is

array split ( string $pattern, string $string [, int $limit] ).

Example

The code is as follows

Copy code

代码如下	复制代码
list($user, $pass, $uid, $gid, $extra) =  split (":", $passwd_line, 5);  ?>

list($user, $pass, $uid, $gid, $extra) = split (":", $passwd_line, 5);
?>

Parse dates that may be separated by slashes, dots, or dashes:

代码如下	复制代码
// 分隔符可以是斜线，点，或横线    $date = "04/30/1973";     list($month, $day, $year) = split ('[/.-]', $date);    echo "Month: $month; Day: $day; Year: $year n"; ?>

Example 2

The code is as follows	Copy code
// The delimiter can be a slash, dot, or horizontal line $date = "04/30/1973"; list($month, $day, $year) = split ('[/.-]', $date); echo "Month: $month; Day: $day; Year: $year n"; ?>

str_split() function

代码如下	复制代码
$str = "Hello Friend"; $arr1 = str_split($str); $arr2 = str_split($str, 3); print_r($arr1); print_r($arr2); ?>

If the optional split_length parameter is specified, each element in the returned array is a character block of length split_length, otherwise each character block is a single character.

If split_length is less than 1, return FALSE. If the split_length argument exceeds the length of string , the entire string will be returned as only one element of the array.

代码如下	复制代码
Array (     [0] => H     [1] => e     [2] => l     [3] => l     [4] => o     [5] =>     [6] => F     [7] => r     [8] => i     [9] => e     [10] => n     [11] => d ) Array (     [0] => Hel     [1] => lo     [2] => Fri     [3] => end )

The code is as follows	Copy code
$str = "Hello Friend"; $arr1 = str_split($str); $arr2 = str_split($str, 3); print_r($arr1); print_r($arr2); ?>

The above routine will output:

The code is as follows	Copy code
Array ( [0] => H [1] => e [2] => l [3] => l [4] => o [5] => [6] => F [7] => r [8] => i [9] => e [10] => n [11] => d ) Array ( [0] => Hel [1] => lo [2] => Fri [3] => end )

chunk_split() function

string chunk_split ( string $body [, int $chunklen [, string $end ]] )
This function is useful for splitting a string into small pieces. For example, convert the output of base64_encode() into a string that conforms to RFC 2045 semantics. It inserts end (default is " ") after every chunklen (default is 76) characters. This function returns a new string without modifying the original string.
Example #1 chunk_split() Example

The code is as follows

Copy code

代码如下	复制代码
// 使用 RFC 2045 语义格式化 $data $new_string = chunk_split(base64_encode($data)); ?>

// Format $data

using RFC 2045 semantics $new_string = chunk_split(base64_encode($data));

?>

explode — Split one string into another

代码如下	复制代码
// 示例 1 $pizza  = "piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = explode(" ", $pizza); echo $pieces[0]; // piece1 echo $pieces[1]; // piece2 // 示例 2 $data = "foo:*:1023:1000::/home/foo:/bin/sh"; list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data); echo $user; // foo echo $pass; // * ?>

Example #1 explode() Example

The code is as follows	Copy code
// Example 1 $pizza = "piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = explode(" ", $pizza); echo $pieces[0]; // piece1 echo $pieces[1]; // piece2 // Example 2 $data = "foo:*:1023:1000::/home/foo:/bin/sh"; list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data); echo $user; // foo echo $pass; // * ?>
