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.";
}
?>

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, $search) !== false) {
echo Success! ;
} else {
echo Fail ;
}
该法典将只找到一条有准确的$search/code>的线体(例如包括白色空间)。 如果你重新配置超文本,则检查PHP s。 班级。 或者,你可以利用reg子来吸引你们所需要的东西。
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.";
}
?>
