1. Get all pictures on the web page:
Copy the codeThe code is as follows:
<?php
//Get the content of the specified address and store it in $text
$text=file_get_contents('https:///');
//Get all img tags and store them in the two-dimensional array $match
preg_match_all('/<img[^>]*>/i', $text, $match);
//Print out match
print_r($match);
?>
2. Get the first picture on the web page:
Copy the codeThe code is as follows:
<?php
//Get the content of the specified address and store it in $text
$text=file_get_contents('https:///');
//Get the first img tag and store it in the two-dimensional array $match
preg_match('/<img[^>]*>/Ui', $text, $match);
//Print out match
print_r($match);
?>
3. Get specific div block data in the specified web page:
Copy the codeThe code is as follows:

$text=file_get_contents('https:///');
//Remove line breaks and whitespace characters (serialized content requires use)
//$text=str_replace(array("/r","/n","/t","/s"), '', $text);
//Take out the content of the div tag and id is PostContent and store it in the two-dimensional array $match
preg_match('/<div[^>]*[^>]*>(.*?) <//div>/si',$text,$match);
//Print out match[0]
print($match[0]);
?>
4. Combination of 2 and 3 above:
Copy the codeThe code is as follows:
<?php
//Get the content of the specified address and store it in $text
$text=file_get_contents('https:///');
//Take out the content of the div tag and id is PostContent and store it in the two-dimensional array $match
preg_match('/<div[^>]*[^>]*>(.*?) <//div>/si',$text,$match);
//Get the first img tag and store it in the two-dimensional array $match2
preg_match('/<img[^>]*>/Ui', $text, $match2);
//Print out match2[0]
print_r($match2[0]);
?>
