I am trying to divide CSV into Two String LHS_String and RHS_String. For Example, I have the below CSV -
customer^id,record^id
customer^fname,record^first_name
cusomer^gender,record^gender
The Output should be like -
LHS_String : customer^id
RHS_String : record^id
Short answer, read over http://php.net/manual/en/function.explode.php
Example:
<?php
$data = "customer^id,record^id\r\n";
$data .= "customer^fname,record^first_name\r\n";
$data .= "cusomer^gender,record^gender\r\n";
$p1 = explode("\r\n", $data);
$p2 = array();
foreach($p1 as $key => $line){
$p2[$key] = explode(",", $line);
}
echo "LHS_String : " . $p2[0][0] . "\r\n";
echo "RHS_String : " . $p2[0][1] . "\r\n";
?>

$concate = "<ul>";
foreach ($arr as $key => $val)

Im trying to display 2 or more unique random results from a text file, How do I do that please?
But I need unique results and not 2 or more of the same.
Currently using this code, but it only returns 1 random result:
<?php
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$randArrayIndexNum = array_rand($textArray);
$randPhrase = $textArray[$randArrayIndexNum];
?>
<?php echo $randPhrase ?>
I would use something like that
shuffle($textArray);
echo $textArray[0];
echo $textArray[1];
http://php.net/manual/tr/function.shuffle.php
You can give a shot to this also. Code is not tested. I am collecting the used into an array, and check, is that used before.
$text = file_get_contents('flatFileDB.txt');
$textArray = explode("\n", $text);
$used = array();
$countOfRandoms = 2;
$randoms = array();
$i = 1;
do {
if ($countOfRandoms == $i) {
break;
}
$randArrayIndexNum = array_rand($textArray);
if (in_array($randArrayIndexNum, $used)) {
continue;
}
$used[] = $randArrayIndexNum;
$random = $textArray[$randArrayIndexNum];
$i++;
} while (true);

I have using this code between echo "";
<?php
for ($i=0; $i<$tot; $i++)
{
$rt = date ( "d-m-Y", $y[$i] ) ;
}
?>
Please specify how to implement this code between echo "";
<?php
$output = 'for ($i=0; $i<$tot; $i++){ ';
$output .= '$rt = date ( \'d-m-Y\', $y[$i] );';
$output .= '}';
echo $output;
?>
For readability I separated it into 4 lines, but you can see how it could easily be refactored into one echo statement.
The key idea here is that by declaring strings with ' instead of ", php will not interpret the $ signs as variables. Additionally, in order to include single quotes within the string itself, a backslash escape character is required as in \'d-m-Y\'
