我正在处理以下代码。如何强制在每个td中使用tr直到循环结束？

<?php
$countries = ["Afghanistan","Albania","Algeria","Andorra","Angola","Anguilla","Antigua &amp; Barbuda","Argentina","Armenia","Aruba","Australia","Austria","Azerbaijan","Bahamas","Bahrain","Bangladesh","Barbados","Belarus","Belgium","Belize","Benin","Bermuda","Bhutan","Bolivia","Bosnia &amp; Herzegovina","Botswana","Brazil","British Virgin Islands","Brunei","Bulgaria","Burkina Faso","Burundi","Cambodia","Cameroon","Cape Verde","Cayman Islands","Chad","Chile","China","Colombia","Congo","Cook Islands","Costa Rica","Cote D Ivoire","Croatia","Cruise Ship","Cuba","Cyprus","Czech Republic","Denmark","Djibouti","Dominica","Dominican Republic","Ecuador","Egypt","El Salvador","Equatorial Guinea","Estonia","Ethiopia","Falkland Islands","Faroe Islands","Fiji","Finland","France","French Polynesia","French West Indies","Gabon","Gambia","Georgia","Germany","Ghana","Gibraltar","Greece","Greenland","Grenada","Guam","Guatemala","Guernsey","Guinea","Guinea Bissau","Guyana","Haiti","Honduras","Hong Kong","Hungary","Iceland","India","Indonesia","Iran","Iraq","Ireland","Isle of Man","Israel","Italy","Jamaica","Japan","Jersey","Jordan","Kazakhstan","Kenya","Kuwait","Kyrgyz Republic","Laos","Latvia","Lebanon","Lesotho","Liberia","Libya","Liechtenstein","Lithuania","Luxembourg","Macau","Macedonia","Madagascar","Malawi","Malaysia","Maldives","Mali","Malta","Mauritania","Mauritius","Mexico","Moldova","Monaco","Mongolia","Montenegro","Montserrat","Morocco","Mozambique","Namibia","Nepal","Netherlands","Netherlands Antilles","New Caledonia","New Zealand","Nicaragua","Niger","Nigeria","Norway","Oman","Pakistan","Palestine","Panama","Papua New Guinea","Paraguay","Peru","Philippines","Poland","Portugal","Puerto Rico","Qatar","Reunion","Romania","Russia","Rwanda","Saint Pierre &amp; Miquelon","Samoa","San Marino","Satellite","Saudi Arabia","Senegal","Serbia","Seychelles","Sierra Leone","Singapore","Slovakia","Slovenia","South Africa","South Korea","Spain","Sri Lanka","St Kitts &amp; Nevis","St Lucia","St Vincent","St. Lucia","Sudan","Suriname","Swaziland","Sweden","Switzerland","Syria","Taiwan","Tajikistan","Tanzania","Thailand","Timor L'Este","Togo","Tonga","Trinidad &amp; Tobago","Tunisia","Turkey","Turkmenistan","Turks &amp; Caicos","Uganda","Ukraine","United Arab Emirates","United Kingdom","Uruguay","Uzbekistan","Venezuela","Vietnam","Virgin Islands (US)","Yemen","Zambia","Zimbabwe"];


echo '<table>';
 foreach ($countries as $country){
   echo '<tr><td>'.$country.'</td></tr>';
 }
echo '</table>';

    ?>

正如你所看到的，我能够将每个项目添加到一行，但我需要每个项目有5个，最后一个不管有多少（肯定少于5个）。

Answer 1

当索引可被5整除时，您可以有条件地关闭并打开tr

echo '<table>';
echo '<tr>';
foreach ($countries as $k=>$country){
    if($k%5 ==0 && $k!=0){
       echo "</tr><tr>";
    }
    echo '<td>'.$country.'</td>';
 }
echo "</tr>";
echo '</table>';

但我建议你使用div或css技术列表来解决这个问题，这是更好的解决方案

如何在表中的每个TR元素上动态填充TD的确切数量？
