PHP - Echo Lines From Text File
I have a .txt file containing hundreds of lines of Names (e.g. Brad, Jennifer, etc.)
What coding can I use to only echo the first 20? Similar TutorialsHi
I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems.
1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?
for($x = 1;$x<=40;$x++) {
$lines = file("$filename.html");
echo $lines[rand(0, count($lines)-1)]."<br>";
}
I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text without the html code?P.S file_get_contents doesn't work either have tried that one.
2nd Problem:
As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?
My code:
if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}
If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.
Hi All, If someone types in my textarea without any hard returns, it echos the entire text on a single line, which expands my site very very far and screws up the layout. how can I echo the text but limit the number of characters per line before I insert my own line break? The code is just: Code: [Select] echo $message; I need to read all the rows from a text file between two specific lines into an array where I can process them. I then need to do the same thing again until the end of the file. The file is too large to read the entire file into an array. The number of rows that are between the key lines are variable. This is what I have so far to read the first set of rows into the array but it is only reading the first row when in fact in this case there are 15. Any pointers as to where I am going wrong please?
if ($_POST['srch']=="Import") {
//open file for reading
$family_rec=[];
$file_handle = fopen($fn, "r");
if(!$file_handle){echo "Could not open file";}
while(!feof($file_handle)) {
$line = fgets($file_handle);
if ((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false)) {
$famref = explode("@", $line);
$line = fgets($file_handle);
//echo $line."<br>";
do{
$family_rec[]=$line;
$line = fgets($file_handle);
//echo $line."<br>";
}
while((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false));
print_r($family_rec);
}//end of family
}//end of while not eof
}//end of import

Thanks! How would I open a text file from another server and echo it. http://mysite.com/news/feed.txt Hi, Have a text file that is being read. I want to print the contents however I want each line of the text file to appear on a new line in the browser. So far $str = file_get_contents('records.txt'); $lines = explode("\n", $str); echo $lines[0]; Help appreciated <td><label for='images'> <b>File to upload:</b> </label></td> <td><input type='file' name = 'drama_image' '<?php echo $row['drama_image']; ?>'/></ </tr> <?php $target_path = "images/"; $target_path = $target_path . basename( $_FILES['images']['name']); if(move_uploaded_file($_FILES['images']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['images']['name']). " has been uploaded"; } else{ echo $row['drama_image']; } ?> ['drama_image'] is the name of the file I wanna echo it out in the box of file upload so when I save , the default picture will still be there instead of being overwritten as the box does not have any value in it. Thanks ahead of time, I have been working this all week end but get lost.... a. I want to insert all the lines from file1.txt into file2.txt . b. I want the all lines in file1.txt to be inserted in file2.txt starting at "<image>" tag label in file2.txt. c. I would like to overwrite all lines that start with the "<image>" tag in file2.txt with the insert (text in file1.txt contains <image> tag also). file2.txt has lines above and below the insert point <image>. The insert text (file1.txt) could be as many as twenty lines (records) all/each beginning with the<image>tag. Here is what I have done so far. <? $key = '<image>'; //a text tag in $file1 and $file2 //copy file $file = "file1.txt"; $file2= 'file2.txt"; $newfile = "filetemp.txt"; copy($file, $newfile) or exit("could not copy $file"); //load file array $fc = fopen ($file, "r"); while (!feof ($fc)) { $buffer = fgets($fc, 4096); $lines[] = $buffer; } fclose ($fc); //open same file and use "w" to clear file ,not sure this is needed $f=fopen($newfile,"w") or die("$file did not open"); /* uncomment to debug print_r($lines); print "<br>\n"; */ //loop through array 'foreach foreach($lines as $line) { fwrite($f,$line); //rewrite $line in file if (strstr($line,$key)){ //find $key in each line fwrite($f,$newline."\n"); } //rewrite $line in file } fclose($f); copy($newfile, $file2) or exit("could not copy $newfile"); ?> Again thanks ahead of time, I just keep losing the flow, old I guess. Tom Hi! What i can't figure out, is how to delete between 2 given strings in another file. Explanation: I have a file, it contains following: Code: [Select] ### Start of content 0 ### Some Radom Lines with text 1 ### End of content 0 ### ### Start of content 1 ### Some Radom Lines with text 2 ### End of content 1 ### ### Start of content 2 ### Some Radom Lines with text 3 ### End of content 2 ### And so on, now i need code, which can find line i give and delete between. Something like this: If, i give string: Code: [Select] ### Start of content 0 ### Then it will delete this line to the Code: [Select] ### End of content 0 ### Hope you can help! All the best: Mart L. If I want to read in and process a CSV of a 1000 lines how easy is it to do without a database? By process, I mean read in the data and do simple manipulations + compare each line with a line from another file, that maybe have 50 lines I was just concerned that I might start hogging the CPU and memory of the server trying to process 1000 lines of data It's VERY important that I can do WITHOUT a database I'd only consider a database if it proves that not using will take too much CPU and memory I've only just began considering making the application - can't give full details - as I've got to figure them out myself! Any general advice would be great Thanks OM I have a form that is processed using PHP (post method) and there is a textarea people will enter text into. After processing, the text is displayed to the user. However, if the user did a Carriage Return (i.e. hit Enter) when they originally entered the text, that text does NOT show on a new line when displayed later. For example, if they type this into the text area... "Hello there (they hit Enter here) How are you (they hit Enter here) Good I hope" It will display like this, all on one line: "Hello there How are you Good I hope" In other words, it doesn't seem to remember that Enter was hit. Is there some way to "preserve" the fact that someone hit the "Enter" key, so that when text is displayed later, it will show the text on a new line if the user in fact hit "Enter" when originally typing it. I am probably not using the right terms in the right spots (i.e. newline, carriage return, enter, etc) but I think you get the picture Let me know if anyone knows how to do this. Thanks! is this possible? Hey all need some help with the subject title. Have a user text file with all information(Name, address, passwords, etc..) Need to be able to select the user based on Checkbox selection then hit delete button and all users checked will be removed from the txt file and thus removed from HTML page. Im using PHP to show contents of the txt file into my HTML page. So far i have: <?php $file = fopen("user.txt","r"); echo '<table border="0" width="100%"> <tr> <th>Select</th> <th>Username</th> <th>Password</th> <th>FirstName</th> <th>LastName</th> <th>Email</th> <th>Address</th> </tr> '; while(!feof($file)) { $user = explode(":", fgets($file)); echo '<tr> <td><input type="checkbox" name="chkDelete" id = "chkDelete" value="select" /></td> <td>' . $user[0] . '</td> <td>' . $user[1] . '</td> <td>' . $user[2] . '</td> <td>' . $user[3] . '</td> <td>' . $user[4] . '</td> <td>' . $user[5] . '</td> </tr>'; echo '</table>'; fclose($file); ?> Am unsure as to how i would go about doing this, help would be greatly appreciated! Thanks in advanced, Daniel. Hey guy, I really need your help with this. I have Input from a text area, in this format: a b c d e f g 12 34 435 124 What I need do to is to output only a certain line from every block of text, every block is divided by one or more empty lines. I have done this: $input = $_POST["input"]; $lines = explode("\r",$input); $num = count($lines); $line_to_extract = $_POST['line_to_extract']; for($i=0;$i<$num;$i++) { if($i == $line_to_extract) { echo 'Line '.$i.': '.$lines[$i].'<br />'; } } What I need to do is to detect the empty line so I can keep track of the line to extract. PLEASE HELP!!! for($i=0; $i!=count($account_data); $i++){ echo "\n::: ".strtoupper($account_data[$i][0])." :::\n"; if($account_data[$i][1] != "" && stristr($account_data[$i][0], "@") && stristr($account_data[$i][0], ".")){ list($place[0],$place[1],$place[2],$place[3]) = authorize($account_data[$i], $game_link); if($place[2] > 1 && strlen($place[3]) == 40){ $filename = 'auth-keys.txt'; $fp = file($filename,'a+'); $data = $place[2]." ".$place[3]."\r\n"; file_put_contents($filename, $data, FILE_APPEND); echo $data; } else echo "Account Skipped: wrong password/email combo, or a login error...\n"; $echo = file_put_contents($filename, FILE_APPEND); } else echo "Account Skipped: invalid email or blank password...\n"; } echo "\n::: PROGRAM FINISHED, YOU CAN CLOSE THIS AT ANY TIME :::"; sleep(10000); You see where I tried to put $echo file_put_contents etc... On success the acct writes a security id and a security auth key to a file, ever acct puts the tokens on a new line every acct... now when an acct echos account skipped, how can I make it print the echo on the file new line instead of nothing being writen and it just skipping the account I have an edit page but whenever I click edit the pathname of the original file is not in the file box so everytime I hit the save button , it will be considered as no file so my previous image or file will be overwritten by "nothing". Ok, here's my code: How do i make it so that it outputs a maximum of only 5 results from the query where the img file exists. When I add LIMIT to the sql query it doesnt work so I guess its something else, but I have no clue. Can anyone help? $query = mysql_query("SELECT * FROM table WHERE date >= '$now' ORDER BY max(date) desc"); while ($row = mysql_fetch_assoc($query)) { $cid = $row['cat_id']; $title = $row['name']; $seoname = $row['seourl']; $img = 'images/'.$seoname.'.jpg'; if (!file_exists($img)) { $img = ''; } else { $img = 'images/'.$seoname.'.jpg'; } if (!empty($img)) { echo '<a href="images/'.$seoname.'/"><img src="'.$img .'" style="width:528px;" alt="" /></a>' . "\n"; } } Thanks. Hi
I echo out images from a folder. The problem is that I have a html file in the same folder but I don't want to echo that out. How can I write my code to get rid of the html in the output?
Here my code:
<?php
$filetype = '*.html';
$dirname = substr('$filetype');
$i=0;
if (isset($_POST['submit2']))
{
//get the dir from POST
$selected_dir = $_POST['myDirs'];
//now get the files from within the selected dir and echo them to the screen
foreach(glob($selected_dir . DIRECTORY_SEPARATOR . '*') as $dirname)
{
echo substr($dirname, 0, -4);
echo '<img src="'.$dirname.'" />';
echo "<label><div class=\"radiobt\"><input type='radio' name='radio1' value='$i'/></div></label>";
}
}
?>
P.S. when I echo out : substr($dirname, 0, -4); I want to get ride of the html filename there too. How can I do so something like this?
