read and write to file....

minhas_amar

hello...

I am new to php .. and I wanted to make a holidays list...
I want to use a file (XML or TXT) and store the holidays in them and get the php code to display the holidays based on the month....

The only thing is, most likely if I use txt files... I might have to use 12 files ?? 1 for each month...

also .. I need to get 2 pieces of data from each line

example for the month of '12':

24:Christmas Eve
25:Christmas Day
26:Boxing Day

so I need to determine the month, then find the month file.... (any idea?)
and then I add need to the contents to the file... but I need to sort it according to the day... ??


<?php 


// Read the entire file into the variable $file_contents 

$filename = '/path/to/file.txt'; 
$fp = fopen( $filename, 'r' ); 
$file_contents = fread( $fp, filesize( $filename ) ); 
fclose( $fp ); 

// Place the individual lines from the file contents into an array. 

$lines = explode ( "\n", $file_contents ); 

// Split each of the lines into a day and a event pair 
// and attempt to match them to $PHP_DAY and $PHP_EVENT. 

foreach ( $lines as $line ) { 

    list( $day, $event ) = explode( ':', $line ); 

    // display $day and $event in table


    break; 

    } 
} 

?>

// amount of digits to use in the counter when displayed
$pad = 10;
// open the log file (if it exists) and read in the current count
if (file_exists($logpath))
{
$count = file_get_contents($logpath);
}
else
{ // else if it does not exist, the initial count will be 0
$count = 0;
}
// increment the count by 1
$count++;
// open the log file for writing, ensuring that it has been locked for
// writing before doing so.
// note that if the file does not already exist, an attempt will be made to create it!
$file = fopen($logpath, 'w'); // the 'w' indicates writing mode
if (flock($file, LOCK_EX))
{ // do an exclusive lock
fwrite($file, $count); // write out the updated count
flock($file, LOCK_UN); // release the lock
}
fclose($file);
// set the zero padding for the count to the value defined previously, then
// display the count onscreen.
$count = str_pad($count, 5, '0', STR_PAD_LEFT);
echo $count;
?>

Would it not be a great deal easier to use mysql?

well i did think of that and I do have access to the MySql database...

but I am not very good with running queries via php...

also... that example is nice for file fucnctions.... but I need to store 2 pieces of data on 1 single line with "append mode" while the counter will only store a single number and uses "write mode" which over-rides the old data..

well basicly I need to know is how do I use that 2 pieces of data on a single line and put them in html table format...

but thanks for the example...

       <table>


<?php
$current_month = date("m");

$filename = '/path/to/' . $current_month . '.txt'; 
$fp = fopen( $filename, 'r' ); 
$file_contents = fread( $fp, filesize( $filename ) ); 
fclose( $fp ); 

// Place the individual lines from the file contents into an array. 

$lines = explode ( "\n", $file_contents );


foreach ( $lines as $line ) { 

    list( $day, $event ) = explode( ':', $line ); 

echo "<tr>";
echo "<td width='26%'>";
echo "<b><font face='Verdana' size='1'>" . $day . "-" . $current_month . "</font></b>";
echo "</td>";
echo "<td width='74%'>";
echo "<b><font face='Verdana' size='1'>" . $event . "</font></b>";
