Question

我试图与未与超文本链接的XML文本相匹配,并将列出超文本链接。但是,它只是阿雷拉。什么是错了? 增编

<?php
$content = file_get_contents( http://phobos.apple.com/version );
$download = preg_match_all( ~(.*)/iPhone/(.*)Restore.ipsw~ , $content, $matches);
echo $matches[0];
?>

Example Text to convert into Link http://appldnld.apple.com/iPhone4/061-7939.20100908.Lcyg3/iPhone3,1_4.1_8B117_Restore.ipsw

如果对等,应列于下文。

Answer 1

rel=“nofollow”>document。

matches
Array of all matches in multi-dimensional array ordered according to flags.

The default flags argument is PREG_PATTERN_ORDER:

Orders results so that $matches[0] is an array of full pattern matches, $matches[1] is an array of strings matched by the first parenthesized subpattern, and so on.

因此,对于您来说,$matches [0] 是与您的格格格文相匹配的座标的array,$matches > > 是array<> > > > >与>/code>对应的子座标的>>> > > /em> 对应的座标的代号:<2><<><>>><>>>>>>>>>>>>> >。例如:



php >print_r($matches[2]);
Array
(
    [0] => 061-4313.20080226.Sw39i/iPhone1,1_1.1.4_4A102_
    [1] => 061-4313.20080226.Sw39i/iPhone1,1_1.1.4_4A102_
    [2] => 061-4313.20080226.Sw39i/iPhone1,1_1.1.4_4A102_
    [3] => 061-4313.20080226.Sw39i/iPhone1,1_1.1.4_4A102_
     ... etc etc
)


因此,$matches[j][i]系指jth lect group of the ith对等。 (带) 是整个配对座标。

Answer 2

感谢。因此,

<?php
$content = file_get_contents( http://phobos.apple.com/version );

$download = preg_match_all( ~(.*)/iP(.*)Restore.ipsw~ , $content, $matches, PREG_PATTERN_ORDER);

 echo "Key: <br>"; 
 print_r($matches[0]); 
 echo "<p>URL: <br>"; 
 print_r($matches[1]);
?>

一方面需要将案文转换为链接,另一方面将案文与一些辅导结合起来。

<?php


    $content = file_get_contents( http://phobos.apple.com/version );

    $matches = "~(.*)/iP(.*)Restore.ipsw~";

    if(preg_match($matches, $content, $url)) {

    echo preg_replace($matches,  <a href=" .$url[0]. " rel="nofollow"> .$url[0]. </a> , $matches);

    }


?>

问题在于将案文转换成仅显示1个超级链接,其余部分将不显示。 http://codepad.org/v4YFfS7i” rel=“nofollow”http://codepad.org/v4YFfS7i
