打开文本文件读取逗号分隔值

Question

I have the following code:

$pollids  = "pollids.txt";
$contents = file_get_contents($pollids);
list($pollid) = explode(',', $contents);
echo $pollid;

This opens a text file containing a comma separated list of text: value1,value2,value3 etc...

However it only echo's the first piece of text in the file. How can I get it to loop/fetch them all?

Secondly, once I have these values, perhaps stored in an array, can i feed them into this piece of script?

$summize = new summize;
$search = $summize->search('searchterm');
$text = $search->results[0]->text;

So that ('searchterm') is replaced by each value in the file? Again i suspect some kind of loop within a loop?

Answer 1

Try this:

$pollids  = "pollids.txt";
$contents = file_get_contents($pollids);
$pollfields = explode(',', $contents);

echo $pollfields[0]; // Prints the value in first "cell"
echo $pollfields[1]; // The second
echo $pollfields[2]; // And so on

Or, in a loop:

foreach($pollfields as $field) {
    echo $field;
}

explode creates an array of fields separated by ,, so $pollfields is an array of those fields, and you can feed them to your second snippet like this:

$summize = new summize;
foreach($pollfields as $field) {
    $search = $summize->search($field);
}
$text = $search->results[0]->text;

Without knowing more of how summize works, that should be what you need.
