Question

我是php的初学者，我有这样的字符串：

$test = http://localhost/biochem/wp-content/uploads//godzilla-article2.jpghttp://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg

我想将字符串拆分为数组：

Array(
[0] => http://localhost/biochem/wp-content/uploads//godzilla-article2.jpg
[1] => http://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg
)

我该怎么办？

Answer 1

$test = 'http://localhost/biochem/wp-content/uploads//godzilla-article2.jpghttp://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg';
$testurls = explode('http://',$test);
foreach ($testurls as $testurl) {
    if (strlen($testurl)) // because the first item in the array is an empty string
    $urls[] = 'http://'. $testurl;
}
print_r($urls);

Answer 2

您要求使用正则表达式解决方案，所以在这里...

$test = "http://localhost/biochem/wp-content/uploads//godzilla-article2.jpghttp://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg";
preg_match_all('/(http:\/\/.+?\.jpg)/',$test,$matches);
print_r($matches[0]);

该表达式查找以http://开头并以.jpg结尾的字符串部分，其间包含任何内容。这会完全按照要求拆分您的字符串。

输出：

Array
(
    [0] => http://localhost/biochem/wp-content/uploads//godzilla-article2.jpg
    [1] => http://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg
)

如果它们总是像这个vith substr（）函数引用那样你可以拆分它们：http://php.net/manual/en/function.substr.php但是如果它们在长度上是动态的。您需要在第二个“http：//”之前获得;或其他任何不太可能使用的符号，然后使用explode函数参考：http://php.net/manual/en/function.explode.php $string = "http://something.com/;http://something2.com"; $a = explode(";",$string);

尝试以下方法：

<?php
$temp = explode('http://', $test);
foreach($temp as $url) {
    $urls[] = 'http://' . $url;
}
print_r($urls);
?>

Answer 5

$test = 'http://localhost/biochem/wp-content/uploads//godzilla-article2.jpghttp://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jp';

array_slice(
    array_map(
        function($item) { return "http://" . $item;}, 
        explode("http://",  $test)), 
    1);

Answer 6

为了通过正则表达式回答这个问题，我想你想要这样的事情：

$test = "http://localhost/biochem/wp-content/uploads//godzilla-article2.jpghttp://localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg";
    $keywords = preg_split("/.http:\/\//",$test);
    print_r($keywords);

它会返回您需要的内容：

Array
(
 [0] => http://localhost/biochem/wp-content/uploads//godzilla-article2.jp
 [1] => localhost/biochem/wp-content/uploads/life-goes-on-wpcf_300x111.jpg
)
