Php Data File Array Element Length

Is there any limit to the length of an array element in a flat data file?

For instance, I have a flat file that I might end up having 200 rows, with each row containing 15 elements. Most of the elements will be about 20 characters or less, but a couple of the elements might be 300-400 characters.

I'm guessing there is no limit.

And since each row will be longer than one "line" in a .txt file, how best to mark the end of a row?

[I assume that using a database is probably the better way to do this, but on this particular website I'm working on that isn't an option.]

Howdy,

I have a page on my site that displays events I have uploaded. Below is the code that displays the event title.

I want to know if there is a simple way to limit the characters of the title that a view will see. For example, limiting the title to 10 characters. So, if I had an event titled "My awesome new event". You would see "My awesome..."

Hope this makes sense. I'm not sure if you will need to see more of the code to help me, thank you!

<a href ="event-description.php?eid=<?php echo $data->EventId?>"<span class="events-title"><?php echo $data->EventTitle ?>

Maximum String Variable Length In Contact Form?

Similar Tutorials

View Content

Hi,
I have a Flash contact form that sends its name, e-mail, and message variables to a PHP script. The script works fine if the message is under ~700 characters, but anything more and the script won't post the message at all. An e-mail with just the name and e-mail address will come through to my inbox (which is embarrassing as a potential client sent me a contact form e-mail about a development job ).

Is there some way to check the maximum character length for a string variable? Or to set its length to something higher?

This is my php. Thank you!!

$senderEmail     = $_POST['userEmail'];

Help With Sorting A 2d Array

Hello!

I have a 2D array that look as follows:

$test["name"][0] = "arnold";
$test["name"][1] = "nate";
$test["name"][2] = "steve";

$test["id"][0] = 2;
$test["id"][1] = 0;
$test["id"][2] = 1;

This means arnold has an ID of 2, nate has an ID of 0 and steve has an ID of 1.
Now I want to sort the array based on the ID value, so I want to achieve the following result:

$test["name"][0] = "nate";
$test["name"][1] = "steve";
$test["name"][2] = "arnold";

How would I achieve this? Help much appreciated.

Hi - I'm modifying some PHP code that someone else wrote. Below is a snippet of code that basically takes mp3 files files within all the folders in a directory, and creates an RSS feed. In the resulting feed, the files are intermingled in date order.

Instead, I'd like them sorted by the directory that they are in. So, if there are files in these directories:

01-First
02-Second
03-Third

I'd like all the files in the "01-First" directory to come before the "02-Second" directory and so on. Within each directory the files can be sorted as they currently are. The name of the directory in the code is signified by $dir_name.

I tried sort() and array_multisort() but I couldn't get either of them to work the way I wanted. Any thoughts?

if ($url_params['mode'] == 'rss2') {

print getRSSHeader('UTF-8', $device, $vm_config, $vm_name, $web_master, $logo_image,$context);
    $mailboxes = array();
if ($dev_dir = @opendir($VMHome . $device)) { //might fail if mailbox has not received first message yet
while ($f = readdir($dev_dir)) {
     if (!eregi("tmp","$f") && !eregi("\.+","$f") && !eregi("Exclude-From-CD", "$f")) { //skip tmp directory and Exclude-From-CD Directories
     array_push($mailboxes,"$f"); #collect all existing mailboxes
     }
}
     array_multisort($mailboxes, SORT_DESC);
foreach ($mailboxes as $mailbox) {
$files=array();
$dir_name = $VMHome . $device . '/'. $mailbox .'/';
$dir = opendir($dir_name);
while ($f = readdir($dir)) {
if (eregi("\.txt",$f)){ #if filename matches .txt in the name
     array_push($files,"$f"); #push into $files array
}
}
foreach($files as $file){
   $props = getProperties($dir_name, $file);
   $uid = getMP3File($dir_name, $file, $props, $device, $mailbox, $vm_config, $vm_name,$context);
   print getRSSItem ($props, $uid, $dir_name, $device, '/' . $mailbox . '/', $context);
}
}
}
print '
</channel>
</rss>';
}

while ($row = mysql_fetch_array($result))
{

"</td><td>",
$row['owner'],
"</td><td>",
$row['team_name'];

$result1 = mysql_query( "
SELECT bye, owner_pts
FROM schedule
WHERE team = $i");
$num_rows = mysql_num_rows($result1);

while ($row1 = mysql_fetch_array($result1))
