Remove text from a PHP string

1. usually, regular expression is not recommended for HTML parsing. But if you just want something quick, you can use:

   <?php
   
   $s = '[caption id="attachment_13" align="alignnone" width="235" caption="Event 1"]
      <img src="image.png" />
   [/caption] ';
   
   if (preg_match('/<img[^>]*>/', $s, $matches)) echo $matches[0];
   
   ?>
   

   output:

   <img src="image.png" />

2. preg_match('/<img src=[^>]+>/', $value, $imgTag);
   echo $imgTag[0];

3. Try

   $str = "[caption id="attachment_13" align="alignnone" width="235" caption="Event 1"]
      <img src="image.png" />
   [/caption] ";
   $arr = explode ( '<img' , $str);
   $arr2 = explode ( '>' , $arr[1]);
   
   echo '<img' . $arr2[0] . '>';

4. You could, however, change the [] with <> and then do the strip_tags

   $replaceThis = array('[', ']');
   $withThis = array('<', '>');
   echo strip_tags(str_replace($replaceThis, $withThis, $value), '<img>');

5. try some regexp :
   http://www.php.net/manual/en/function.preg-replace.php

   something like that something should work with minimum adaptation (i don’t work with PHP since a long long long time xD) :

   <?php
   $pattern = '/.*(<img[^>]+)>.*/';
   $remplacement = '$1';
   echo preg_replace($pattern, $replacement, $value);
   ?>
