PHP使用array_push

标签： php arrays foreach

我想要实现的目标：
在$currentSchoolPosition[0];消息中显示3rd值，例如(Position Here)。

当前问题：
当使用$currentSchoolPosition[0];上方的foreach字符串时，如果我将字符串移到array();下方，foreach显示3rd Position，则会显示<?php /* Current User ID */ $currentUserID = get_current_user_id(); /* Current User SchoolName */ $currentSchoolName = get_the_author_meta( 'School-Name', $user_ID); /* Current User SchoolRegion */ $currentSchoolRegion = get_the_author_meta( 'School-Region', $user_ID); /* Current User SchoolPosition Array - Empty */ $currentSchoolPosition = array(); /* Message */ echo '<p>'.$currentSchoolRegion.' Leaderboard</p>'; echo '<p>Your school <strong>'.$currentSchoolName.'</strong> is currently in (Position Here) position</p>';/* POSITION HERE */ /* Get 'Subscriber' Users */ $subscribers = get_users('role=subscriber'); /* Subscriber School Array - Empty */ $schoolArray = array(); /* Counter - Start at '1' */ $i = 1; /* Table */ echo '<table class="table table-striped">'; foreach ($subscribers as $subscriber) { $schoolName = $subscriber->get( 'School-Name' ); $schoolRegion = $subscriber->get( 'School-Region' ); /* If 'subscriber' region = current user region push school name(s) to 'schoolArray' */ if($schoolRegion === $currentSchoolRegion){ array_push($schoolArray, $schoolName); } } /* Count matching 'schoolArray' values */ $subscriberValues = array_count_values($schoolArray); /* Reverse 'schoolArray' order - High to Low */ arsort($subscriberValues); /* Reset Counter value - Start at '1' */ $i = 1; foreach ($subscriberValues as $key => $value) { $counter = $i++; echo '<tr>'; /* If 'counter' = '1' display 'Champion School' else display 'counter' value */ if ($counter === 1) { echo '<th scope="row">Champion School</th>'; echo '<td>'.$key.'</td>'; echo '<td>'.$value.' Sign Ups</td>'; } else { echo '<th scope="row">'.$counter.'</th>'; echo '<td>'.$key.'</td>'; echo '<td>'.$value.' Sign Ups</td>'; } echo '</tr>'; /* Get current school position */ if($key === $currentSchoolName){ array_push($currentSchoolPosition, $counter); } } echo '</table>'; echo $currentSchoolPosition[0].' Position'; /* POSITION VALUE HERE */ ?> 。

如何在foreach之前显示位置值？

提前谢谢！

PHP 

<?php
  /* Current User ID */
  $currentUserID = get_current_user_id();
  /* Current User School Name */
  $currentSchoolName = get_the_author_meta('School-Name', $user_ID);
  /* Current User School Region */
  $currentSchoolRegion = get_the_author_meta('School-Region', $user_ID);
  /* Current School Position */
  $currentSchoolPosition = array();
  /* Get Subscribers */
  $subscribers = get_users('role=subscriber');
  /* Subscriber School Array */
  $schoolArray = array();
  /* Foreach Subscribers as Subscriber */
  foreach ($subscribers as $subscriber) {
    /* Subscriber School Name */
    $schoolName = $subscriber->get('School-Name');
    /* Subscriber School Region */
    $schoolRegion = $subscriber->get('School-Region');
    /* If Subscriber School Region matches Current User School Region PUSH School Name to Array */
    if ($schoolRegion === $currentSchoolRegion) {
      array_push($schoolArray, $schoolName);
    }
  }
  /* Reverse School Array Order - High to Low */
  arsort($subscriberValues);
  /* Count Matching Schoole Array Values */
  $subscriberValues = array_count_values($schoolArray);
  /* Foreach Get Current School Position */
  $i = 1;
  foreach ($subscriberValues as $key => $value) {
    $counter = $i++;
    if ($key === $currentSchoolName) {
      array_push($currentSchoolPosition, $counter);
    }
  }
  /* Header Message */

您可以先构建表（通过foreach），然后在使用从循环创建的数据后最终回显它 - 如下所示：

<?php

  /* Current User ID */
  $currentUserID = get_current_user_id();
  /* Current User SchoolName */
  $currentSchoolName = get_the_author_meta( 'School-Name', $user_ID );
  /* Current User SchoolRegion */
  $currentSchoolRegion = get_the_author_meta( 'School-Region', $user_ID );
  /* Current User SchoolPosition Array - Empty */
  $currentSchoolPosition = array();
  /* Get 'Subscriber' Users */
  $subscribers = get_users( 'role=subscriber' );
  /* Subscriber School Array - Empty */
  $schoolArray = array();
  /* Counter - Start at '1' */
  $i = 1;

  /* Table */
  $table = '<table class="table table-striped">';

  foreach ( $subscribers as $subscriber ) {
    $schoolName = $subscriber->get( 'School-Name' );
    $schoolRegion = $subscriber->get( 'School-Region' );
    /* If 'subscriber' region = current user region push school name(s) to 'schoolArray' */
    if ( $schoolRegion === $currentSchoolRegion ) {
      array_push( $schoolArray, $schoolName );
    }
  }
  /* Count matching 'schoolArray' values */
  $subscriberValues = array_count_values( $schoolArray );
  /* Reverse 'schoolArray' order - High to Low */
  arsort( $subscriberValues );
  /* Reset Counter value - Start at '1' */
  $i = 1;
  foreach ( $subscriberValues as $key => $value ) {
    $counter = $i++;
    $table .= '<tr>';
    /* If 'counter' = '1' display 'Champion School' else display 'counter' value */
    if ( $counter === 1 ) {
      $table .= '<th scope="row">Champion School</th>';
      $table .= '<td>' . $key . '</td>';
      $table .= '<td>' . $value . ' Sign Ups</td>';
    }
    else {
      $table .= '<th scope="row">' . $counter . '</th>';
      $table .= '<td>' . $key . '</td>';
      $table .= '<td>' . $value . ' Sign Ups</td>';
    }
    $table .= '</tr>';
    /* Get current school position */
    if ( $key === $currentSchoolName ) {
      array_push( $currentSchoolPosition, $counter );
    }
  }
  $table .= '</table>';

  /* Message */
  echo '<p>' . $currentSchoolRegion . ' Leaderboard</p>';
  echo '<p>Your school <strong>' . $currentSchoolName . '</strong> is currently in (Position Here) position</p>';
   /* POSITION HERE */
  echo $currentSchoolPosition[0] . ' Position';
   /* POSITION VALUE HERE */

  // print out the table
  echo $table;

?>
