使PHP数组结果显示在页面的不同区域

标签： php arrays hyperlink

我创建了以下代码，如果链接已经存在，则将ezproxy代码添加到链接中。我的页面上有6个链接，4个已经预先添加，2个没有。将前置添加到2个链接没有它工作正常，但我如何调用结果来替换不包含前缀的链接？

这是我的页面：http://lis7440.slis.wayne.edu/eh3343/final/electronic.php

我需要用阵列结果替换ACP Pier和BioMed链接。我用来预装的代码是：

<?php



 $array = array("http://proxy.lib.wayne.edu/login?url=http://accessanesthesiology.mhmedical.com", "http://proxy.lib.wayne.edu/login?url=http://accessmedicine.mhmedical.com",
 "http://proxy.lib.wayne.edu/login?url=http://accesspharmacy.mhmedical.com", "http://proxy.lib.wayne.edu/login?url=http://accesssurgery.mhmedical.com", 
 "http://online.statref.com/Default.aspx?grpalias=MLC", "http://www.biomedcentral.com");



foreach($array as $value) {
    $pattern = '/^http?:\/\/proxy\.lib\.wayne\.edu\/login\?url=/';
    if (preg_match($pattern, $value)) {

    echo "<a href=$value>Database</a>";
    }
    else{
    $value = "http://proxy.lib.wayne.edu/login?url=".$value;

    }
    echo "<a href=$value>Database</a>";
    }
    ?>

如何使用新的前置阵列结果链接替换这2个链接（段落部分中的ACP Pier和BioMed）？

感谢您的任何建议。

整个代码是：

您只需在IF

中添加第二个回音 
$array = array("http://proxy.lib.wayne.edu/login?url=http://accessanesthesiology.mhmedical.com", "http://proxy.lib.wayne.edu/login?url=http://accessmedicine.mhmedical.com","http://proxy.lib.wayne.edu/login?url=http://accesspharmacy.mhmedical.com", "http://proxy.lib.wayne.edu/login?url=http://accesssurgery.mhmedical.com", "http://online.statref.com/Default.aspx?grpalias=MLC", "http://www.biomedcentral.com");

foreach($array as $value) {
$pattern = '/^http?:\/\/proxy\.lib\.wayne\.edu\/login\?url=/';
    if (preg_match($pattern, $value)) {
        echo "<a href=$value>Database</a>";
    }
    else{
        $value = "http://proxy.lib.wayne.edu/login?url=".$value;
        echo "<a href=$value>Database</a>";
    }
}

使用虚拟数据库编辑添加的PHP解决方案 

<?php

$resources = array();
// Add Resources to Array (fake DB)
array_push($resources, array(
    'link' => 'http://proxy.lib.wayne.edu/login?url=http://accessanesthesiology.mhmedical.com',
    'title' => 'AccessAnesthesiology (McGraw Hill)',
    'text' => 'In AccessAnesthesiology, physicians and residents can access a compendium of medical resources, including exclusive procedural videos,

    managements, critical care, and perioperative medicine.'
));

array_push($resources, array(
    'link' => 'http://proxy.lib.wayne.edu/login?url=http://accessmedicine.mhmedical.com',
    'title' => 'AccessMedicine',
    'text' => 'A repository of medical knowledge from internal medicine, cardiology, genetics, pharmacy, diagnosis and management, basic sciences,

array_push($resources, array(
