php中字符串怎麼當數組

implode 使用一個字符串将數組變成字符串

<?php $array = array('lastname', 'email', 'phone'); $comma_separated = implode(",", $array); echo $comma_separated; // lastname,email,phone var_dump(implode('hello', array())); // string(0) "" ?>

explode — 使用一個字符串分割另一個字符串，返回一個數組

<?php // 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; // * ?>

這裡如果字符串沒有任何符号可以進行分割的話，就需要考慮别的方法了

str_split — 将字符串轉換為數組

<?php $str = "Hello Friend"; $arr1 = str_split($str); $arr2 = str_split($str, 3); print_r($arr1); print_r($arr2); ?> 輸出結果 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 )
