如何在php中搜索精确的数字

如何搜索准确的号码

这段代码是这样工作的

如果我搜索 24626838（这是完全否），它什么也没有显示

之后如果我搜索这个 no 2462683（这不完整）

所以它显示的结果是这样的

像这样

24626838
24626838
24626836
24626832
24626837

我想要这样的结果

如果我搜索这个号码24626838（这是完整的号码）

所以它的显示完全像这样

24626838
24626838

我该怎么做请帮我解决这个问题

这是代码

<?php

    //connect to database

     mysql_connect('localhost','root','');
     mysql_select_db('member');

$alphabet = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'); 
foreach ($alphabet as $letter) { 
echo "<a href=\"viewuser.php?letter=" . $letter . "\" class=\"style2\">" . $letter . "</a>&nbsp;|&nbsp;"; 

} 


echo "<br>";
echo "<a href=\"index.php?\" class=\"style2\">Show All</a></p><br /> <form method=\"post\" action=\"?\">

如果您想搜索确切的数字，请使用column='$number'代替column LIKE $number。在里面WHERE子句，我建议将偶数括在单引号中，因为我最近遇到了使用的问题WHERE column = 1234这也匹配12345, but WHERE column = '1234'仅匹配非常精确的数字。
