如何通过配对阵列进行阵列和搜索?
原标题:How to put URL in array and search through array for matching string?

我正试图通过URL寻找一种配对体,但以下的代码似乎行不通。

<?php

$url = "http://www.drudgereport.com";

$search = "a";
$file = file($url);

if (in_array($search,$file)) {
    echo "Success!";
} else {
    echo "Can t find word.";
}

?>
最佳回答

如果你只是找寻在网页上发生的扼杀事件,你可以使用。

$str = file_get_contents($url);
if (strpos($str, $search) !== false) {
    echo  Success! ;
} else {
    echo  Fail ;
}
问题回答

in_array():如果阵列成员与你的针头相等的话。

很多网站的行文不通,只有a

另外,allow_url_f open。 是的?

As @alex says, check is allow_url_fopen is enabled.
Also you can use
strpos to search the string:

<?php

$url = "http://www.drudgereport.com";

$search = "a";
$file_content = file_get_contents($url);

if (strpos($file_content, $search) !== false) {
    echo "Success!";
} else {
    echo "Can t find word.";
}

?>
