[英]HTML make link clickable in <p> element filled with text from PHP
我遇到以下問題:我正在顯示一個文本,該文本存儲在 mySql 數據庫中的<p>
元素中。 當此文本包含網址(例如: https://google.com/ )時,此網址不可點擊並突出顯示。 是否有任何解決方案可以突出顯示此<p>
元素中的 url?
$projectDescription = "Some text..Link1: https://google.com/";
<p class="project-overview-text"><?php echo($projectDescription); ?></p>
您可以嘗試以下具有正則表達式並按標簽包裝 URL 的代碼。 這適用於任何類型的 URL
<?php
//Regular Expression to filter urls
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
//your text
$projectDescription = "Some text..Link1: https://google.com/";
// Checking if any url is present in the text
if(preg_match($reg_exUrl, $projectDescription, $url)) {
// Wrap urls by <a>
$projectDescription = preg_replace($reg_exUrl, '<a href="'.$url[0].'">'.$url[0].'</a> ', $projectDescription);
}
echo $projectDescription;
?>
嘗試這個:
$projectDescription = "Some text..Link1: https://google.com/";
<p class="project-overview-text"><a href="your_link_here"><?php echo($projectDescription); ?></a></p>
嘗試這個?
<?php
$projectDescription = "Some text..Link1: https://google.com/";
$position_http = strpos($projectDescription,"http") ;
$position_com = strpos($projectDescription,"com") ;
$url = substr($projectDescription, $position_http, $position_com+2);
?>
<p class="project-overview-text"><?php echo substr($projectDescription, 0, $position_http);?>
<a href="<?php echo $url?>" class="project-overview-text"><?php echo($url); ?></a> </p>
要支持多個 URL,以下代碼是正確的!
$regex = '/\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|$!:,.;]*[A-Z0-9+&@#\/%=~_|$]/i';
preg_match_all($regex, $projectDescription, $matches);
$urls = $matches[0];
// go over all links
foreach($urls as $url) {
$projectDescription = str_replace($url, '<a href="'.$url.'">'.$url.'</a> ', $projectDescription);
}
