Question

我要在n个逗号后插入新行。例如，我得到了这个值：385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,402,403,404,405,406,407,408,409,410,411,412,413,414,415,416,417,418,419,420,421,422,423,424,425,426

我怎么能全部呼应它们，但是每5个逗号应该有一个换行符？

385,386,387,388,389, 390,391,392,393,394, 395,396,397,398,399, 400,401,402,403,404, 405,406,407,408,409, 410,411,412,413,414, 415,416,417,418,419, 420,421,422,423,424, 425,426

Answer 1

这是一种方法：

// Get all numbers
$numbers = explode(',', $str);
// Split into groups of 5 (n)
$lines = array_chunk($numbers, 5);
// Format each line as comma delimited
$formattedLines = array_map(function ($row) { return implode(',', $row); }, $lines);
// Format groups into new lines with commas at the end of each line (except the last)
$output = implode(",\n", $formattedLines);

Answer 2

尝试这样。

您可以使用逗号将字符串爆炸并检查每5个字符位置应该有换行符。
您可以使用5的分隔键进行检查。 0的余数

请注意，键从0开始，所以我添加了（key + 1），使其从1开始。

$string = "385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,402,403,404,405,406,407,408,409,410,411,412,413,414,415,416,417,418,419,420,421,422,423,424,425,426";    
$stringexplode = explode(",", $string);
$countstringexplode = count($stringexplode);
foreach($stringexplode as $key => $val)
{
    $keyIncrement = $key+1;
    echo $val.($countstringexplode == $keyIncrement ? "" : ",") ;
    if(($keyIncrement) % 5 == 0)
    echo "<br>";
}


     ?>

尝试一下

<?php
//Start //Add this code if your values in string like that
$string = "385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,402,403,404,405,406,407,408,409,410,411,412,413,414,415,416,417,418,419,420,421,422,423,424,425,426";
$string_array = explode(',', $string);
//End //Add this code if your values in string like that

//If you have values in array then direct use below code skip above code and replace $string_array variable with yours 

end($string_array);        
$last = key($string_array);

foreach ($string_array as $key => $value) {
    if($last==$key){
        echo $value;
    }else{
        echo $value.',';
    }
    if(($key+1)%5==0){
        echo "<br />";
    }
}

?>
