PHP get images and div content instances in Web pages

The simple way to share the content of images and div in PHP is through regular expressions.

1. Get all the pictures in the webpage:

<?  //$text=file_get_contents(' http://www.jbxue.com/'//    preg_match_all $text $match/ /   Print_r($match?>

2. Get the first picture in the Web page:

<? PHP //  $text=file_get_contents(' http://www.jbxue.com/'//   Preg_match$text$match); // Print out Match Print_r ($match);? >

3. Gets the specific div chunk data for the specified page:

 <? php  //   $text  =file_get_contents  ('/HTTP/ www.jbxue.com/' );  //  remove line breaks and whitespace characters (required for serialization)//$text =str_ Replace (Array ("/R", "/n", "/t", "/S"), ", $text); Take out the DIV tag with id postcontent and store it in a two-dimensional array $match  preg_match  ('/<div[^& gt;] *id= "Postcontent" [^>]*> (. *) <//div>/si ',  $text ,  $match   //  print out match[0]  print  ( $match  [0? 

4. The above 2 and 3 are combined:

<?PHP//Obtain the content of the location and save it to the $text$text=file_get_contents(' http://www.jbxue.com/'); //Take out the div tag with id postcontent and store it in a two-dimensional array $matchPreg_match('/<div[^>]*id= ' Postcontent "[^>]*> (. *?) <//div>/si ',$text,$match); //gets the first IMG tag and stores it in a two-dimensional array $match 2Preg_match('/]*>/ui ',$text,$match 2); //print out match2[0]Print_r($match 2[0]); ?>
