I'm new to php and after researching I haven't found an answer I understand. I am using php with html. I am reading in from text files (file_get_contents). I am doing a restaurant menu where the first item is "burgers" (burgers.txt). Second is "chicken", etc. I am separating these text files using with explode function. Here is my code
<?php
$dir = 'C:\xampp\htdocs\posplus\txtfiles';
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;//array of files
}
$dot = array_shift($files);
$dotdot = array_shift($files);
$numfiles = count($files);//counts number of text files
for($f=0;$f<$numfiles;$f++)
{
$filearray = array();
$filearray[$f] = file("txtfiles/".$files[$f]); //txtfile."burgers.txt"
$linessarray = array();
$linesarray[$f] = count($filearray[$f]); //number of lines in each file (to be displayed on different lines)
$namesarray = array();
$namesarray[$f] = pathinfo($files[$f]); //get name of file without extension(.txt)
${'array'.$f} = explode("
", file_get_contents("txtfiles/".$files[$f]));
?>
</head>
<body>
<?php
echo'<table align="center">
<tr>
<th colspan = "3">'.$namesarray[$f]['filename'].'</th>
</tr>';
//filename without ".txt"
for ($i=0; $i<$linesarray[$f]; $i++) { //loop through each text file
$part = explode(',', ${'array'.$f}[$i]);//split each line in text file by comma example (cheeseburger, large, €3.00, made from finest beef)
echo'<tr>
<td id="name">'.$part[0].'</td>
<td id="size">'.$part[1].'</td>
<td id="price">'.$part[2].'</td>
</tr>
<tr>
<td id="desc" colspan="3">'.$part[3].'</td>
</tr>';
}}
?>
The above code is working fine printing the tables one after the other. My problem is I need to make it dynamic. The job requires using only one screenful as it is a display menu. It needs to be dynamic in the way that if a font is a certain size I only want for example 10 items on a page. Items 1-10 on first page, 11-20 on second, etc. The sizing calculations are no problem but as can be seen from my code I am looping through the text files. I need to do a page break or similar after a certain number of items. If for example I have 6 items on first txt file and 8 on the second, I would need a page break 4 items into my second file.
The only way I can think of to do it would be a foreach merge_recursive loop such as this
$newArray = array_merge_recursive($array0, $array1, $array2); //merge burgers.txt with chicken.txt, etc
foreach ($newArray as $key => $value) {
echo "$key - $value <br />";
}
This will merge arrays and assign a key to all of them allowing me to do page breaks after say 10 items in my $newArray. Problem is I don't know how many text files I will be reading from so I cannot hard code it as it's done above. Is there a way of merging all my arrays through some kind of loop where one array gets added to the one before?
As I said I'm a beginner and I have next to no help so any help would be appreciated. I am aware that the above code is also very poor so suggestions of better ways of doing it may also be helpful. Apologies for the long winded question. Go easy on me.
