我有一個(gè)來(lái)自 Wordpress 頁(yè)面的數(shù)據(jù)庫(kù)數(shù)組：dev-user-20190424.php<?php$wb_users = array( array( "Username" => "Azmina", "Level" => "form-5", "School" => "KOLEJ D PATINGGI ABANG HJ ABDILLAH, SARAWAK", "SchoolID" => 4522, ), array( "Username" => "Gudako", "Level" => "form-5", "School" => "KOLEJ D PATINGGI ABANG HJ ABDILLAH, SARAWAK", "SchoolID" => 4522, ), array( "Username" => "Takatosaijo29", "Level" => "form-5", "School" => "SEKOLAH MENENGAH KEBANGSAAN BAHANG, SABAH", "SchoolID" => 4210, ), array( "Username" => "Obon", "Level" => "form-5", "School" => "SEKOLAH MENENGAH KEBANGSAAN BAHANG, SABAH", "SchoolID" => 4210, ), array( "Username" => "Rayana12", "Level" => "form-5", "School" => "SEKOLAH MENENGAH KEBANGSAAN BAHANG, SABAH", "SchoolID" => 4210, ), array( "Username" => "kaiyuanbeh", "Level" => "form-5", "School" => "SEKOLAH MENENGAH KEBANGSAAN PERMATANG RAWA, PULAU PINANG", "SchoolID" => 4250, ), array( "Username" => "Divyabharthi", "Level" => "form-5", "School" => "SEKOLAH MENENGAH KEBANGSAAN PETALING, WP KL", "SchoolID" => 4244, ), array( "Username" => "blackchocolatecake", "Level" => "form-4", "School" => "SEKOLAH MENENGAH KEBANGSAAN POI LAM, PERAK", "SchoolID" => 4375, ), );所以我想要實(shí)現(xiàn)的是通過(guò)循環(huán)數(shù)組 $wb-users 來(lái)顯示另一個(gè) WordPress 頁(yè)面上的用戶總數(shù)，如果 SchoolID 與當(dāng)前用戶學(xué)校 id 變量匹配，則對(duì)其進(jìn)行計(jì)數(shù)。然后頁(yè)面上會(huì)顯示用戶總數(shù)。

我相信這基本上就是你要找的。
$schoolID = 4522;
$studentTotal = 0;
for ($i = 0; $i < count($wb_users); $i++) {
if ($wb_users[$i]['SchoolID'] === $schoolID) {
$studentTotal++;
}
}
您需要 1. 循環(huán)遍歷主數(shù)組中的數(shù)組。2. 將“SchoolID”鍵與您的學(xué)校 ID 變量進(jìn)行比較。3. 匹配時(shí)增加計(jì)數(shù)器。
