PHP 将文本(标题）放在每个数组类别之前 - PHP Place text (title) before each array category

PHP Place text (title) before each array category

本文关键字：数组文本标题 PHP | 更新日期: 2023-09-27

这个函数应该回显所有的单打和双打数字。（例如 01 - 01 02）。

我尝试使用以下代码在每个"类别"之前放置一个标题，但它无法正常工作。

应该是这样的

单打

01,02,03

双打

01 02， 03 04， 05 06

你能帮我解决这个问题吗？谢谢！

function check_stats($todas){
    $arrlength = count($todas);

    for($x = 0; $x < $arrlength; $x++) {

        $arrlength2 = count($todas[$x]);
        if($arrlength2==1){
            echo 'single'.'</br></br>';
            list($a) = explode(" ", implode(" ", $todas[$x]));  
            echo $a; echo '</br>';
        }   
        if($arrlength2==2){
            echo 'double'.'</br></br>';
            list($a,$b) = explode(" ", implode(" ", $todas[$x]));  
            echo $a.' '.$b; echo '</br>';
        }   
    } //for
} //function

您正在尝试将单打和双打分开。并且您要单独打印它们。在尚未检测到所有内容的情况下，无法单独打印它们。然后，您需要检测所有类别，然后可以单独打印它们。为此，您应该在检测时保存类别，并在检测后打印保存的类别。

function check_stats($todas){
    $singles = array(); // an array to save single numbers
    $doubles = array(); // an array so save doubles
    foreach ($todas as $toda) { // cleaner and beautifier than for
        if (count($toda) == 1) { // direct compare without extra $arrlength2
            $singles[] = $toda[0]; // will push $toda[0] to $singles array
        } else if (count($toda) == 2) { // when put else compares less
            $doubles[] = $toda[0] . ' ' . $toda[1];
        }
    }
    // then you can do whatever with $singles and $doubles
    echo 'SINGLES' . PHP_EOL;
    foreach ($singles as $single) {
        echo $single . PHP_EOL;
    }
    echo 'DOUBLES' . PHP_EOL;
    foreach ($doubles as $double) {
        echo $double . PHP_EOL;
    }
}

编辑#1：如果有超过 2 种变量，则可以将它们保存在数组中。

function check_stats($todas){
    $result_array = array();
    foreach ($todas as $toda) {
        $result_array[count($toda)] = implode(' ', $toda);
        // the above code will save each single or double or triple or etc
        // in an index in their size
    }
    return $result_array; // better return it and use out of function
}
$result = check_stats($todas);
// now print them
foreach ($todas as $key => $toda) {
    echo $key . PHP_EOL; // print count (that is index)
    foreach ($toda as $t) {
        echo $t . PHP_EOL;
    }
}
