PHPで文字列を分割する関数とは何ですか

array explode( string separator, string string [, int limit] )<br/>

<?php<br/>$str = &#39;one|two|three|four&#39;;<br/>print_r(explode(&#39;|&#39;, $str));<br/>print_r(explode(&#39;|&#39;, $str, 2));<br/>// 负数的 limit（自 PHP 5.1 起）<br/>print_r(explode(&#39;|&#39;, $str, -1));<br/>?><br/>

Array<br/>(<br/>    [0] => one<br/>    [1] => two<br/>    [2] => three<br/>    [3] => four<br/>)<br/>Array<br/>(<br/>    [0] => one<br/>    [1] => two|three|four<br/>)<br/>Array<br/>(<br/>    [0] => one<br/>    [1] => two<br/>    [2] => three<br/>)<br/>

<?php<br/>$str = &#39;one two three&#39;;<br/>$arr1 = str_split($str);<br/>$arr2 = str_split($str, 3);<br/>print_r($arr1);<br/>print_r($arr2);<br/>?><br/>
