在下面的函数中,读取了src,请问如何再读取里的title
function get_pic_list($content='')
{
$pattern="//";
preg_match_all($pattern,$content,$match);
$arr_pic = array();
$i = 0;
foreach($match[1] as $imgsrc)
{
$arr_pic[$i]['src'] = $imgsrc;
$i++;
}
return $arr_pic;
}
回复讨论(解决方案)
看看是否这样
function get_pic_list($content=''){ $pattern="/<img src="/static/imghwm/default1.png" data-src="/assets/ico_set.gif" class="lazy" .*?src=[\'|\"](.*?(?:[\.gif|\.jpg]))[\'|\"].*?title=[\'|\"](.*?)[\'|\"].*?[\/]? alt="如何读取<img>里的title" >/"; preg_match_all($pattern,$content,$match); $arr_pic = array(); $i = 0; for($i=0,$len=count($match[1]); $i<$len; $i++){ $arr_pic[$i]['src'] = $match[1][$i]; $arr_pic[$i]['title'] = $match[2][$i]; } return $arr_pic;}$content =<<<TXT<a href="#" class="drop_toggle btn_1 " rel='nofollow'><span> <img src="/static/imghwm/default1.png" data-src="/assets/ico_set.gif" class="lazy" alt="" title="title1" />管理菜单<img src="/static/imghwm/default1.png" data-src="/assets/arrow_down.gif" class="lazy" alt="" title="title2" /></span></a>TXT;$result = get_pic_list($content);print_r($result);
Array( [0] => Array ( [src] => /assets/ico_set.gif [title] => title1 ) [1] => Array ( [src] => /assets/arrow_down.gif [title] => title2 ))
调用后,显示不正确,我本来上传了很多图片,但是只显示出来两张,而且显示出来这两张我用查看源码时,title的值为空。
在下面的调用页面的JS是不是也要做修改??怎么改??
<script> <br /> $(document).ready(function () { <br /> $(".colorboxEx").each(function (i, el) { <br /> $(el).justifiedGallery({rel: 'gal' + i}).on('jg.complete', function () { <br /> $(this).find('a').colorbox({ <br /> maxWidth : '80%', <br /> maxHeight : '80%', <br /> opacity : 0.8, <br /> transition : 'elastic', <br /> current : '' <br /> }); <br /> }); <br /> }); <br /> }); <br /> </script>
你是否每张图片都有title标记?并且title是放在src后面。
可能不是JS的事,因为我把那段JS删掉,也是一样只显示两张没有title值的图片
没有每张都title,有些有,有些没有
加上title试试。没有的加上title=""
刚刚加上了,也只显示一部分,我试了一下,分别把title的值设为1,2,3,4,5,6,7,8,但是只显示了2,4,6,8
是隔一个显示一个
如果不确定是否每张图都有title标记,需要二次正则获取。
修改如下:
function get_pic_list($content=''){ $pattern="/<img src="/static/imghwm/default1.png" data-src="/assets/ico_set.gif" class="lazy" .*?src=[\'|\"](.*?(?:[\.gif|\.jpg]))[\'|\"].*? alt="如何读取<img>里的title" >/"; preg_match_all($pattern,$content,$match); $arr_pic = array(); $i = 0; for($i=0,$len=count($match[1]); $i<$len; $i++){ $arr_pic[$i]['src'] = $match[1][$i]; preg_match('/title=[\'|\"](.*?)[\'|\"]/', $match[0][$i], $match1); $arr_pic[$i]['title'] = isset($match1[1])? $match1[1] : ''; } return $arr_pic;}$content =<<<TXT<a href="#" class="drop_toggle btn_1 " rel='nofollow'><span> <img src="/static/imghwm/default1.png" data-src="/assets/ico_set.gif" class="lazy" alt="" title="title1" />管理菜单<img src="/static/imghwm/default1.png" data-src="/assets/arrow_down.gif" class="lazy" alt="" title="title2" /> <img src="/static/imghwm/default1.png" data-src="/assets/arrow_down123.gif" class="lazy" alt="" /></span></a>TXT;$result = get_pic_list($content);print_r($result);
Array( [0] => Array ( [src] => /assets/ico_set.gif [title] => title1 ) [1] => Array ( [src] => /assets/arrow_down.gif [title] => title2 ) [2] => Array ( [src] => /assets/arrow_down123.gif [title] => ))
如果还有问题,可以把$content发出来看看。
可以了,谢谢

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
