That might be a fool question, but I need to know how to solve this:
Notice: Array to string conversion in C:\xampp\htdocs\search_view.php on line 248
Why am I getting this message, what can I do to solve it?
echo'<div id="thumb">
'.$ids = array();
$ids[] = $results['idGames'];
for ($i = 0; $i < count($ids); $i++) {
$id = $ids[$i];
$v = $results['total_votes'];
$tv = $results['total_value'];
if ($v)
$rat = $tv / $v;
else
$rat = 0;
$j = $ids[$i];
$id = $ids[$i];
echo '<div class="topcontentstar">
<div id="' . $id . '" class="">';
for ($k = 1; $k < 6; $k++) {
if ($rat + 1 > $k)
$class = "" . $k . " ratings_stars_index ratings_vote";
else
$class = "" . $k . " ratings_stars_index ratings_blank";
echo '<div class="' . $class . '"></div>';
}
echo '
</div>
</div></div>;
Because in this part of code you tried to convert an array to string via concatenation
echo'<div id="thumb">
(line 248) '.$ids = array();
Separate them: $ids = array()
echo'<div id="thumb">
(line 248) ';
$ids = array();
echo'<div id="thumb">
(line 248) '.$ids = array();
You are concatenating a string and an array, just as the errors says. You are echoing the string, and appending the array $ids to that. Because assigning a value gets a higher precedence than concatenating things, $ids is already an array.
You're doing this:
echo'<div id="thumb">
(line 248) '.$ids = array();
Basically, you can't concatenate array with a string and that's why the error appears.
To fix the error, you can separate the array declaration into a separate line:
echo'<div id="thumb">';
$ids = array();
Hope this helps!
As a side note, I can see a problem in your last few lines:
echo '
</div>
</div></div>;
Should be:
echo '</div></div></div>';

My tags column is like this:
first row: sky - earth - sea
second row: iron - silver - gold
third row: apple - fruit - food
...and so on
Want to create a div from each item, like this:
<div class='tagdown'>sky</div>
<div class='tagdown'>earth</div>
$st = $db->query("select tags from posts");
$arr = array();
$items = "";
while ($row = $st->fetch()) {
array_push($arr, explode(' - ', $row['tags']));
}
foreach($arr as $item) {
$items .= "<div class='tagdown'>" . $item . "</div>\n";
}
echo $items;
Notice: Array to string conversion...
Another Try:
for ($i = 0; $i < count($arr); ++$i) {
$items .= "<div class='tagdown'>" . $arr[$i] . "</div>\n";
}
echo $items;
Notice: Array to string conversion...
Any help?
Dont push and again traverse your array. just print out data in while loop. Try following code:
$items = "";
while ($row = $st->fetch()) {
$arr = explode(' - ', $row['tags']);
$items .= "<div class='tagdown'>".implode("</div>\n<div class='tagdown'>",$arr)."</div>\n";
}
echo $items;
Try like shown below
Example :
<?php
$items = "";
$str = "sky-earth-sea";
$arr = explode("-", $str);
$count = count($arr);
for($i = 0; $i < $count; $i++) {
$items .= "<div class='tagdown'>".$arr[$i]."</div></br>";
}
echo $items;
?>
explode() returns an array and you are pushing an array into an other array
its making 1 2D array you can check thar using print_r($arr);
use this
while ($row = $st->fetch()) {
$tag=explode('-', $row['tags'];
foreach($tag as $t){
array_push($arr,$t ));
}
}
You can also use fetch associative if using mysqli_connect
while ($row = $result->fetch_assoc()) {
array_push($arr, explode(' - ', $row['tags']));
}
foreach($arr as $a) {
foreach($a as $v){
$items .= "<div class='tagdown'>" . $v . "</div>\n";
}
}
echo $items;
-------------- OR -------------
$arr = array();
$items = "";
while ($row = $result->fetch_assoc()) {
$tag = explode(' - ', $row['tags']);
foreach($tag as $v){
$items .= "<div class='tagdown'>" . $v . "</div>\n";
}
}
echo $items;
I need to add data in my database and one way or the other the format must be like,
0 - 0 or 1 - 5
i have tryed =>
mysqli_real_escape_string();
but did not work.
i have also tryed changing the sign to / , * , +, exp.
PHP
$dataBase->_insertDataBase('tableNaam', $input);
function _insertDataBase($tabel,$input){
$velden='';
$waarden='';
$i=0;
foreach($input AS $key=>$value){
$i=$i+1;
if($i !== count($input)){
$a=', ';
}else{
$a='';
}
$velden.=$key.$a;
$waarden.=$value.$a;
unset($a);
}
$sql = "INSERT INTO `$tabel`($velden) VALUES ($waarden)";
$this->_conn()->query($sql);
}
The problem is your SQL statement is giving the equation 5-1 as a value, so the server is doing the math and inserting 4 just like you told it to. You need tell it that it's a literal string by surrounding the values with apostrophe's (i.e. '5-1').
Replace:
foreach ($input AS $key => $value) {
$i = $i + 1;
if ($i !== count($input)) {
$a = ', ';
} else {
$a = '';
}
$velden .= $key . $a;
$waarden .= $value . $a;
unset($a);
}
With:
$velden = array();
$waarden = array();
foreach ($input AS $key => $value) {
$velden[] = $key;
$waarden[] = $value;
}
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
Or possibly even:
$velden = array_keys($input);
$waarden = array_values($input);
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
for ($k = 0; $k < $count; $k++) {
$master[$k] = $namearray[$k], $streetarray[$k], $localityarray[$k], $regionarray[$k], $postalcodearray[$k], $phonearray[$k];
}
I'd like to declare a new array and set values from other arrays already declared. I thought I could just loop through the keys and set the values but this doesn't work for me.
Full code below. I'm parsing yellow pages search results and trying to output search results into a csv file. In the code below I removed the loop and only added a few values to the array to make sure my bug wasn't something else.
<?php
// include required functions
include('simple_html_dom.php');
$url = "http://www.yellowpages.com/" . $_POST['city'] . '-' . $_POST['state'] . '-' . $_POST['postalcode'] . '/' . $_POST['category'] . '?g=' . $_POST['city'] . '%2C+' . $_POST['state'] . '+' . $_POST['postalcode'] . '&q=' . $_POST['category'];
// get DOM from URL
$html = file_get_html($url);
// find all business name
foreach($html->find('h3.business-name') as $name)
//echo $name->innertext . '<br />';
$namearray[] = $name->innertext;
// find all business street address
foreach($html->find('span.street-address') as $street)
//echo $street->innertext . '<br />';
$streetarray[] = $street->innertext;
// find all business city
foreach($html->find('span.locality') as $locality)
//echo $locality->innertext . '<br />';
$localityarray[] = $locality->innertext;
// find all business state
foreach($html->find('span.region') as $region)
//echo $region->innertext . '<br />';
$regionarray[] = $region->innertext;
// find all business postal code
foreach($html->find('span.postal-code') as $postalcode)
//echo $postalcode->innertext . '<br />';
$postalcodearray[] = $postalcode->innertext;
// find all business phone
foreach($html->find('span.business-phone') as $phone)
//echo $phone->innertext . '<br />';
$phonearray[] = $phone->innertext;
?>
<p>Search results for: <?php echo $_POST['category'] . ' ' . $_POST['city'] . ' ' . $_POST['state'] . ' ' . $_POST['postalcode']; ?></p>
<?php
// Output results
$count = count($namearray);
for ($i = 0; $i < $count; $i++) {
echo $namearray[$i] . '<br />';
echo $streetarray[$i] . '<br />';
echo $localityarray[$i] . ',' . $regionarray[$i] . ' ' . $postalcodearray[$i] . '<br />';
echo $phonearray[$i] . '<br />' . '<br />';
}
$list = array (
array($namearray[0], $streetarray[0], $localityarray[0], $regionarray[0], $postalcodearray[0], $phonearray[0]),
array($namearray[1], $streetarray[1], $localityarray[1], $regionarray[1], $postalcodearray[1], $phonearray[1]),
array($namearray[2], $streetarray[2], $localityarray[2], $regionarray[2], $postalcodearray[2], $phonearray[2]),
array($namearray[3], $streetarray[3], $localityarray[3], $regionarray[3], $postalcodearray[3], $phonearray[3])
);
$fp = fopen('hrpsearch.csv', 'w');
foreach ($list as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
?>
Try:
$master = array();
for ($k = 0; $k < $count; $k++) {
$master[$k] = array
( $namearray[$k]
, $streetarray[$k]
, $localityarray[$k]
, $regionarray[$k]
, $postalcodearray[$k]
, $phonearray[$k]
);
}
This will create a new two-dimensional array for you with associated keys for every child array.
Try
for($k = 0; $k < $count; $k++) {
$master[$k] = array(
$namearray[$k],
$streetarray[$k],
$localityarray[$k],
$regionarray[$k],
$postalcodearray[$k],
$phonearray[$k]
);
}
Maybe do you just want to achieve this?
$master[$k] = array($namearray[$k], $streetarray[$k], $localityarray[$k], $regionarray[$k], $postalcodearray[$k], $phonearray[$k]);
I would suggest using instead:
$master[$k]['name'] = $namearray[$k];
$master[$k]['street'] = $streetarray[$k];
...
The retrieval of the data will be more readable.
I think #DaveRandom's answer is what (I imply) you are looking for.
Since a PHP array can be of any type (scalar, array, object, etc.), you need to tell it you are assigning an array with the construct array().
The end result would be:
$master[$k] = array($namearray[$k], $streetarray[$k], $localityarray[$k], $regionarray[$k], $postalcodearray[$k], $phonearray[$k]);
Try this
for ($k = 0; $k < $count; $k++) {
$master[$k] = array($namearray[$k], $streetarray[$k], $localityarray[$k], $regionarray[$k], $postalcodearray[$k], $phonearray[$k]);
}
or is better to create associative array
for ($k = 0; $k < $count; $k++) {
$master[$k] = array('name'=>$namearray[$k],
'street'=>$streetarray[$k],
'city'=>$localityarray[$k],
'region'=>$regionarray[$k],
'postalCode'=>$postalcodearray[$k],
'phone'=>$phonearray[$k]);
}
You also need to check if your array elements are not empty or just put # befor array element like 'name'=>#$namearray[$k]. It will remove any warning if element doesn't exist.
How would I go and split number 12345 into something like this with PHP:
<span>1</span>
<span>2</span>
<span>3</span>
<span>4</span>
<span>5</span>
echo preg_replace('((.))', "<span>$1</span>\n", '12345');
Try with:
$input = 12345;
foreach ( str_split($input) as $char ) {
echo '<span>' . $char . '</span>';
}
With str_split()
<?php
$str="12345";
$str = str_split($str);
foreach ($str as $letter){
echo '<span>'.$letter.'</span>'.PHP_EOL;
}
?>
$str = '12345';
$arr = str_split($str);
foreach ($arr as $char) {
echo '<span>' . $char . '</span>';
}
var arr = explode('', "12345");
Then iterate throgh it with foreach and echo (or do whatever you want with) the tags.
If the input string will be large, something like this will be more memory-friendly and possibly faster because it streams instead of breaking it apart first.
$string = "12345";
for ($i = 0, $j = strlen($string); $i < $j; $i++) {
echo "<span>" . $string{$i} . "</span>\n";
}
I am trying to determine the end of a foreach loop that is seeded with a collection of DOMNodeList. Currently, I am using a for loop would like to avoid having a 'magic' number there. I do know there are only going to be 8 columns, but I would like the code me generic for other applications.
Is it possible to convert this to a Foreach loop? I have tried the end() and next() functions, but they are not returning any data and I suspect that they only work on arrays and not this DOMNodeList collection.
The code is building a CSV file without the trailing ','
Current output is:
"Value 1","Value 2","Value 3","Value 4","Value 5","Value 6","Value 7","Value 8"
Here is an example of code:
$cols = $row->getElementsByTagName("td");
$printData = true;
// Throw away the header row
if ($isFirst && $printData) {
$isFirst = false;
continue;
}
for ($i = 0; $i <= 8; $i++) {
$output = iconv("UTF-8", "ASCII//IGNORE", $cols->item($i)->nodeValue);
$output2 = trim($output);
if ($i == 8) {
// Last Column
echo "\"" . $output2 . "\"" . "\n";
} else {
echo "\"" . $output2 . "\"" . ",";
}
}
You can use:
$cols->length
To retrieve the number of items in a DOMNodeList.
See http://php.net/manual/en/class.domnodelist.php
Edit:
If you change you're code to this, you don't have to worry about the trailing comma, or the length:
$output = array();
foreach ($cols as $item) {
$output = iconv("UTF-8", "ASCII//IGNORE", $item->nodeValue);
$output2 = trim($output);
$output[] = '"' . $output2 . '"';
}
$outputstring = implode(',', $output);
$cols->length
Should give you the number of items in the list
for ($i = 0; $i < $cols->length; $i++) {
// ...
if ($i == $cols->length - 1) {
// last column
