how to split the data into array? - php

Question

I have stored the data in a mysql database, I want to know how I can split the data in each different array before output them in php?
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'myusername');
define('DB_PASSWORD', 'mypassword');
define('DB_DATABASE', 'mydbname');
$errmsg_arr = array();
$errflag = false;
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link)
{
die('Failed to connect to server: ' . mysql_error());
}
$db = mysql_select_db(DB_DATABASE);
if(!$db)
{
die("Unable to select database");
}
if($errflag)
{
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
echo implode('<br />',$errmsg_arr);
}
else
{
$qrytable1="SELECT id, mydata FROM mydb ";
$result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());
while ($row = mysql_fetch_array($result1))
{
echo "<tr><td>".$row['mydata']."</td></tr>";
}
}
?>
On my PHP page it show something like this:
<tr><td>my data 1</td></tr><tr><td>my data 2</td></tr><tr><td>my data 3</td></tr><tr><td>my data 4</td></tr>
I want to split them up by turn into array and output them with each different array to something like this:
mydata1
mydata2
mydata3
mydata4
How I can split the data into array before I could output them in my php?

Answer 1

Are you looking for something like this?
(consider it as an example, but, as #BenM, consider using PDO)
$sql = 'SELECT * FROM country';
$query = mysql_query($sql);
$countries = array();
while ($country = mysql_fetch_assoc($query)){ $countries[] = $country; }
This will allow you to use
foreach ($countries as $country) {
echo $country['name'];
}

Answer 2

Your data is already in an array. That's what this line does:
while ($row = mysql_fetch_array($result1))
{
echo "<tr><td>".$row['mydata']."</td></tr>";
}
If you need to access the array outside of the while loop you could do this..
$myArray = array();
while ($row = mysql_fetch_array($result1)){
echo "<tr><td>".$row['mydata']."</td></tr>";
foreach($row as $key=>$val){
$myArray[$key] = $val;
}
}
actually.. assuming your query returns multiple rows it would be a multidimensional array..
$myArray = array();
$i = 0;
while ($row = mysql_fetch_array($result1)){
echo "<tr><td>".$row['mydata']."</td></tr>";
foreach($row as $key=>$val){
$myArray[$i][$key] = $val;
$i++;
}
}

If I am right than along with getting data in array you want to remove the space in between the data
try this
while ($row = mysql_fetch_array($result1))
{
echo "<tr><td>".$row['mydata']."</td></tr>";
$myArr[] = $row['mydata'];
}
foreach($myarr as $key=>$value)
{
$myArr[$key] = str_replace(" ","",$value);
}
str_replace will remove the spaces.

You can used this,
$db->setQuery($query);
$rows = $db->loadObjectList();
$i=0;
foreach($rows as $row){
//$row;
$image = json_decode($row->images);
// split code
$str = utf8_encode($row->introtext);
$order = array("<p>", "</p>", "\n", "\r");
$replace = '';
$introtext = str_replace($order, $replace, $str);
$introtext_split = explode("|", $introtext);
$data[0]->designation = preg_replace('#<br />?#', "\n", $introtext_split[0]);
$data[0]->description = preg_replace('#<br />?#', "\n\n", $introtext_split[1]);
$data[0]->small_description = preg_replace('#<br />?#', "\n\n", $introtext_split[2]);
}
In data used any tag, Or this tag replace using following section :
$str = utf8_encode($row->introtext);
$order = array("<p>", "</p>", "\n", "\r");
I think its useful to you.
