Here is an update of your code, this means that you have one url per line. 

Hope this helps, happy coding.

<pre><code>&lt;?php

function url_test( $url ) {
 $timeout = 10;
 $ch = curl_init();
 curl_setopt ( $ch, CURLOPT_URL, $url );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt ( $ch, CURLOPT_TIMEOUT, $timeout );
 $http_respond = curl_exec($ch);
 $http_respond = trim( strip_tags( $http_respond ) );
 $http_code = curl_getinfo( $ch, CURLINFO_HTTP_CODE );
 if ( ( $http_code == "200" ) || ( $http_code == "302" ) ) {
 return true;
 } else {
 // return $http_code;, possible too
 return false;
 }
 curl_close( $ch );
}


$file ="test.txt";
$handle = fopen($file, "r");
if ($handle) {
 while (($line = fgets($handle)) !== false) {
 // process the url
 if(url_test(trim($line))){
 print "Url $line Up\n";
 }else{
 print "Url $line Down\n";
 }
 }

 fclose($handle);
} else {
 // error opening the file.
}

entityMap|blocks|key|59j5p|text|文件(“test.txt”)；将文件的所有行读入一个数组。如果你知道你的文件总是只有一行，你必须像这样读取索引为0的array的元素：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|epp0g|$links+=+file("test.txt");
if(+!url_test(+$links[0])+)+{
++echo+$links[0]+."+is+down!";
}
else+{+
++echo+$links[0]+."+functions+correctly.";+
}++++|code-block|syntax|javascript|d3r7c|但是，如果您的文件可能包含多个URL(每行一个)的列表，那么您必须遍历数组并检查所有URL，如下所示：|35s9e|$links+=+file("test.txt");
foreach+($links+as+$line_num+=>+$link)+{
++if(+!url_test(+$link)+)+{
++++echo+$link+."+is+down!";
++}
++else+{+
++++echo+$link+."+functions+correctly.";+
++}
}|b64og^0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|M|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|N|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|O|9|@]|A|@]|B|$]]|$2|J|4|K|6|E|8|P|9|@]|A|@]|B|$F|G]]|$2|L|4|-4|6|7|8|Q|9|@]|A|@]|B|$]]]]

The file("test.txt"); reads all lines of the file into an array.
If you know your file will always have only one line, you have to read the element of array at index 0 like this:

<pre><code>$links = file("test.txt");
if( !url_test( $links[0]) ) {
 echo $links[0] ." is down!";
}
else { 
 echo $links[0] ." functions correctly."; 
} 
</code></pre>

But if your file may contain a list of multiple URLs (one per line) then you'd have to loop through the array and check all of them like this:

<pre><code>$links = file("test.txt");
foreach ($links as $line_num =&gt; $link) {
 if( !url_test( $link) ) {
 echo $link ." is down!";
 }
 else { 
 echo $link ." functions correctly."; 
 }
}
</code></pre>

entityMap|blocks|key|8usbc|text|问题是file()将返回一个行数组，所以如果文件中只有一个URL，那么可以使用[0]传递第一行，否则在列表中传递并使用foreach()。在设置网址时，使用trim()来确保网址没有杂乱的空格等也是值得的。我还更改了测试，以检查状态代码是否处于一组可能的可接受状态，而不是检查单个值。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|e64o1|多URL代码...|1geh8|function+url_test(+$url+)+{

The problem is that <code>file()</code> will return an array of lines, so if you have just one URL in the file you can use <code>[0]</code> to pass the first line, otherwise pass in the list and use <code>foreach()</code>. It's also worth using <code>trim()</code> to ensure that the URL is clear of any stray spaces etc when setting the URL. I've also changed the test to check if the status code is in a set of possible acceptable statuses rather than checking individual values.

Multi URL code...

<pre><code>function url_test( $url ) {
 $timeout = 10;
 $ch = curl_init();
 foreach ( $url as $link ) {
 curl_setopt ( $ch, CURLOPT_URL, trim($link) );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt ( $ch, CURLOPT_TIMEOUT, $timeout );
 $http_respond = curl_exec($ch);
 $http_code = curl_getinfo( $ch, CURLINFO_HTTP_CODE );
 if ( !in_array($http_code , ["200", "301", "302"] ) ) {
 return false;
 }
 }
 curl_close( $ch );
 return true;
}

$links = file("test.txt");
if( !url_test( $links) ) {
 echo " is down!";
}
else { echo " functions correctly."; }
</code></pre>

1 URL example...

<pre><code>function url_test( $url ) {
 $timeout = 10;
 $ch = curl_init();
 curl_setopt ( $ch, CURLOPT_URL, trim($url) );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt ( $ch, CURLOPT_TIMEOUT, $timeout );
 $http_respond = curl_exec($ch);
 $http_code = curl_getinfo( $ch, CURLINFO_HTTP_CODE );
 if ( !in_array($http_code , ["200", "301", "302"] ) ) {
 return false;
 }
 curl_close( $ch );
 return true;
}


$links = file("test.txt");
if( !url_test( $links[0]) ) {
 echo " is down!";
}
else { echo " functions correctly."; }
</code></pre>

I'm new with .php and I can't make my code work. I have a function that checks if a website is up or down (that works), after that I just try to get link from a .txt file and echo them with the result from check function but I don't seem to get it right. Here is my code:

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;?php

function url_test( $url ) {
 $timeout = 10;
 $ch = curl_init();
 curl_setopt ( $ch, CURLOPT_URL, $url );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt ( $ch, CURLOPT_TIMEOUT, $timeout );
 $http_respond = curl_exec($ch);
 $http_respond = trim( strip_tags( $http_respond ) );
 $http_code = curl_getinfo( $ch, CURLINFO_HTTP_CODE );
 if ( ( $http_code == "200" ) || ( $http_code == "302" ) ) {
 return true;
 } else {
 // return $http_code;, possible too
 return false;
 }
 curl_close( $ch );
}


$links = file("test.txt");
if( !url_test( $links) ) {
 echo $links ." is down!";
}
else { echo $links ." functions correctly."; }
}
