Question

我正在尝试将段落拆分为100个字符的数组。但我的算法不起作用......

在我的输出中第一个我得到100个字符。但第二个我得到200，下一个我得到300我认为......

    $desc = $this->getDescription();

    $desc = preg_replace('/[^a-zA-Z0-9\s]/', ' ', strip_tags(html_entity_decode($desc)));
    $desc = preg_replace('/(\s\s+|\t|\n)/', ' ', $desc);

    $count = strlen($desc);
    $time = ($count/100);

    $x = 0;
    $y = 100;


    for($i = 0; $i<ceil($time);$i++){
        $array[$i] = substr($desc,$x,$y);
        $array[$i] = str_replace(" ", "+", $array[$i]);
        $link[$i] = 'http://translate.google.com/translate_tts?tl=en&q=' . $array[$i];
        $x+= 100;
        $y+= 100;
    }

有人知道这个问题吗？

我得到的输出：

我试图调试它......

Characters: 100 |  x: 0 | y: 100 |
|Characters: 200 |  x: 100 | y: 200 |
|Characters: 300 |  x: 200 | y: 300 |
|Characters: 400 |  x: 300 | y: 400 |
|Characters: 422 |  x: 400 | y: 500 |
|Characters: 322 |  x: 500 | y: 600 |
|Characters: 222 |  x: 600 | y: 700 |
|Characters: 122 |  x: 700 | y: 800 |
|Characters: 22 |  x: 800 | y: 900

Answer 1

$ y是长度，你在循环的每一步都将它增加100。

我建议评论或删除该行：

$y+= 100;

试试这个

$str= "If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length.

$arr = str_split($str, 100);
print"<pre>";
print_r($arr);
