我试图在关联数组上使用foreach循环创建一个html表。这是关于数组的更多细节。

$assoc_array = array(

"0" => array(

"project_id" => "1",

"emp_id" => "123",

"emp_name" => "Max",

"project" => "Java"

),

"1" => array(

"project_id" => "2",

"emp_id" => "123",

"emp_name" => "Max",

"project" => "Java"

),

"2" => array(

"project_id" => "3",

"emp_id" => "124",

"emp_name" => "Max",

"project" => "Java"

),

"3" => array(

"project_id" => "4",

"emp_id" => "124",

"emp_name" => "Max",

"project" => "Java"

),

"4" => array(

"project_id" => "5",

"emp_id" => "125",

"emp_name" => "Max",

"project" => "Java"

),

"5" => array(

"project_id" => "6",

"emp_id" => "125",

"emp_name" => "Max",

"project" => "Java"

)

)

?>

所以我试图用他们的emp_id对它们进行分组。为此，我试图使用下面的逻辑

$assoc_array = array(

"0" => array(

"project_id" => "1",

"emp_id" => "123",

"emp_name" => "Max",

"project" => "Java"

),

"1" => array(

"project_id" => "2",

"emp_id" => "123",

"emp_name" => "Max",

"project" => "Java"

),

"2" => array(

"project_id" => "3",

"emp_id" => "124",

"emp_name" => "Anna",

"project" => "Angular"

),

"3" => array(

"project_id" => "4",

"emp_id" => "124",

"emp_name" => "Anna",

"project" => "PHP"

),

"4" => array(

"project_id" => "5",

"emp_id" => "125",

"emp_name" => "John",

"project" => "Java"

),

"5" => array(

"project_id" => "6",

"emp_id" => "125",

"emp_name" => "John",

"project" => "Java"

)

);

$prevEmpid = '';

$tableData = '';

$tableStartTag = "

$tableEndTag = "

";

$wholeData = "";

$trFixed = "

project id emp id emp nameproject";

foreach($assoc_array as $val) {

if($val['emp_id'] !== $prevEmpid ) {

if($tableData) {

$wholeData = $tableStartTag . $trFixed . $tableData . $tableEndTag;

echo $tableData;

}

$wholeData = '';

$tableData = '';

$prevEmpid = $val['emp_id'];

}

$tableData .= "

" . $val['project_id'] . ""

. "

" . $val['emp_id'] . ""

. "

" . $val['emp_name'] . ""

. "

" . $val['project'] . "";

}

但问题是，我没有得到最后一个表数据，因为foreach循环中的元素会通过其他条件。

任何小帮助都非常感谢。
