Question

我正在尝试将字符串中的文本转换为表情符号。我已经尝试过并且成功了一半。

问题：当我将字符串中的字符替换为表情符号时，链接http://mywebsite.com中的字符“：/”也会被替换。

到目前为止我做了什么：

chat.php

<?php 
require('common.php');
if($_POST && !empty($_POST['title'])){
    $result = $db->add_news($_POST['title']);
}
$text="";
function parseSmiley($text){
    //Smiley to image
    $smileys=array('o:)'=>'angel.gif', ':3'=>'colonthree.gif', 'o.O'=>'confused.gif', ":'("=>'cry.gif', '3:)'=>'devil.gif', ':('=>'frown.gif', ':O'=>'gasp.gif', '8)'=>'glasses.gif', ':D'=>'grin.gif', ">:-("=>'grumpy.gif', '<3'=>'heart.gif', '^_^'=>'kiki.gif', ':*'=>'kiss.gif', ':v'=>'pacman.gif', ':)'=>'smile.gif', '-_-'=>'squint.gif', '8|'=>'sunglasses.gif', ':p'=>'tongue.gif', ':/'=>'unsure.gif', '>:-O'=>'upset.gif', ';)'=>'wink.gif');

    //Now you need to find and replace
    foreach($smileys as $smiley=>$img){
        $text=str_replace(htmlspecialchars($smiley), "<img src='emotions-fb/{$img}'/>", $text);
    }
    //Now only return it
    return $text;
}
?>

db.php中

function get_news(){
    if($result = $this->db->query('SELECT * FROM news WHERE id<>1 ORDER BY add_date DESC LIMIT 50')){
        $return = '';
        while($r = $result->fetch_object()){
            $timing=explode(" ", $r->add_date);

            $return .= '<p>'.wordwrap(htmlspecialchars($r->title), 25, "\n", true).'</p>';
            //$return .='<p>'.$timing[1].' on '.$timing[0].'</p>';
            $return .= '<hr/>';
        }
        return $return;
    }
}

之后我搜索了stackoverflow并得到了类似的东西，但这并没有取代任何文字到图像

    foreach($smileys as $smiley=>$img){
        $smiley=preg_quote($smiley);
        $text=preg_replace("~\b$smiley\b~", "<img src='emotions-fb/{$img}'/>", $text);

    }

我不知道我哪里出错了。提前谢谢。

尝试：

$smileys=array('o:)'=>'angel.gif', ':3'=>'colonthree.gif', 'o.O'=>'confused.gif', ":'("=>'cry.gif', '3:)'=>'devil.gif', ':('=>'frown.gif', ':O'=>'gasp.gif', '8)'=>'glasses.gif', ':D'=>'grin.gif', ">:-("=>'grumpy.gif', '<3'=>'heart.gif', '^_^'=>'kiki.gif', ':*'=>'kiss.gif', ':v'=>'pacman.gif', ':)'=>'smile.gif', '-_-'=>'squint.gif', '8|'=>'sunglasses.gif', ':p'=>'tongue.gif', ':/'=>'unsure.gif', '>:-O'=>'upset.gif', ';)'=>'wink.gif');
$text='Some example text with smile :/ ^_^ and :\'( and link <a href="http://google.com"> my site :/</a>';
foreach ($smileys as $smiley => $img)
{
    $smiley = preg_quote( $smiley );
    $text = preg_replace( "#(?<=\s|^)(?:$smiley)(?=\s|$)?#i", '<img src="emotions-fb/'. $img .'">', $text);
}
echo $text;

无法将文本更改为使用preg_replace的图像
