Its true that the spec at <a href="http://us3.php.net/manual/en/function.str-getcsv.php" rel="noreferrer">http://us3.php.net/manual/en/function.str-getcsv.php</a> doesn't include a standard example, but the user-submitted notes do a decent job of covering it. If this is a form input:

<pre><code>$val = $_POST['value'];
$data = str_getcsv($val);
</code></pre>

<code>$data</code> is now an array with the values. Try it and see if you have any other issues.

blocks|key|2803123|text|我认为你也许应该看看explode来完成这个任务。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2803124|+$values++=+"php,+js,+jquery";

I think you should maybe look at <a href="http://www.php.net/manual/en/function.explode.php" rel="nofollow noreferrer">explode</a> for this task. 

<pre><code> $values = "php, js, jquery";
 $items = explode(",", $values);

 // Would give you an array:
 echo $items[0]; // would be php
 echo $items[1]; // would be js
 echo $items[2]; // would be jquery
</code></pre>

This would probably more efficient than str_getcsv();

Note that you would need to use trim() to remove possible whitespace befores and after item values.

UPDATE:

I hadn't seen str_getcsv before, but read this quote on the manpage that would make it seem a worthwhile candidate:

<blockquote>
 Why not use explode() instead of str_getcsv() to parse rows? 
 Because explode() would not treat possible enclosured parts of 
 string or escaped characters correctly.
</blockquote>

blocks|key|2803177|text|为了简单和可读性，我通常只使用explode()，只有在满足以下两个条件的情况下才添加str_getcsv()：1)主分隔符也用在数据本身中；2)我试图用作主分隔符的标记被另一个不同的字符括起来。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2803178|例如，CSV文件的基本解析器：|2803179|$filename+=+$argv[1];

$AccountsArray+=+explode("\n",+file_get_contents($filename));|code-block|syntax|javascript|2803180|只要$AccountsArray的每个元素没有在数据本身中嵌入"，“，这就可以完美地工作，并且简单易懂：|2803181|foreach+($AccountsArray+as+$entry)+{
++++$acctArr+=+explode(",",+$entry);
}|2803182|然而，数据通常会包含分隔符，此时必须有一个封闭的标记(在本例中为a“)。如果是这样，那么我将切换到str_getcsv()，如下所示：|2803183|foreach+($AccountsArray+as+$entry)+{
++++$acctArr+=+str_getcsv($entry,+",",+"\"");+
}|2803184|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|V|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|W|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|P|5|F|7|Y|8|@]|9|@]|A|$G|H]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

For simplicity and readability, I typically find myself using just explode(), only adding in str_getcsv() if the following two conditions are met: 1) the primary delimiter is also used within the data itself; 2) the token that I'm trying to use as the main delimiter is enclosed by another distinct character.

For example, a basic parser for a CSV file:

<pre><code>$filename = $argv[1];
if (empty($filename)) { echo "Input file required\n"; exit; }
$AccountsArray = explode("\n", file_get_contents($filename));
</code></pre>

As long as each of the elements of $AccountsArray doesn't embed a "," within the data itself, this will work perfectly and is straightforward and easy to follow:

<pre><code>foreach ($AccountsArray as $entry) {
 $acctArr = explode(",", $entry);
}
</code></pre>

However, often the data will contain the delimiter, at which point an enclosing token (a " in this example) has to be present. If so, then I switch to str_getcsv() like so:

<pre><code>foreach ($AccountsArray as $entry) {
 $acctArr = str_getcsv($entry, ",", "\""); 
}
</code></pre>

The code is quite simple, using the <code>Str_getcsv</code> function, we will go 
through each line of the CSV file "images.csv" that is located in the 
same directory as our script.

NOTE: Functions used are compatible with versions of PHP >= 5.3.0

<pre><code>//First, reading the CSV file

$csvFile = file('file.csv');

foreach ($csvFile as $line) {
 $url = str_getcsv($line);

 $ch = curl_init($url[0]);

 $name = basename($url[0]);

 if (!file_exists('directory/' . $name)) {
 $fp = fopen('directory/' . $name, 'wb');
 }

 curl_setopt($ch, CURLOPT_FILE, $fp);
 curl_setopt($ch, CURLOPT_HEADER, 0);
 curl_exec($ch);
 curl_close($ch);
 fclose($fp); 
}
</code></pre>

I want to parse a comma separated value string into an array. I want to try the <code>str_getcsv()</code> php function but I can't find any good examples on how to use it. 

For example I have an input where users submit tags for programming languages (php, js, jquery, etc), like the "tags" input in stackoverflow when you submit a question.

How would I turn an input with example <code>value="php, js, jquery"</code> into an array using str_getcsv?
