This one only covers the first record in the array -- $form[items][0][description]. How could I iterate this to be able to echo succeeding ones i.e
$form[items][1][description];
$form[items][2][description];
$form[items][3][description];
and so on and so forth?
$array = $form[items][0][description];
function get_line($array, $line) {
preg_match('/' . preg_quote($line) . ': ([^\n]+)/', $array['#value'], $match);
return $match[1];
}
$anchortext = get_line($array, 'Anchor Text');
$url = get_line($array, 'URL');
echo '' . $anchortext . '';
?>
This should do the trick
foreach ($form['items'] as $item) {
echo $item['description'] . "<br>";
}
I could help you more if I saw the body of your get_line function, but here's the gist of it
foreach ($form['items'] as $item) {
$anchor_text = get_line($item['description'], 'Anchor Text');
$url = get_line($item['description'], 'URL');
echo "{$anchor_text}";
}
You can use a for loop to iterate over this array.
for($i=0; $i< count($form['items']); $i++)
{
$anchortext = get_line($form['items'][$i]['description'], 'Anchor Text');
$url = get_line($form['items'][$i]['description'], 'URL');
echo '' . $anchortext . '';
}

I'm trying to set the php variables linked to one of my page in the folder, index.html. However, I am getting an error of Name&lang=en"> Any help?
if (isset($result_array)) {

$url = '<a href="index.html">' . urlencode($result['Name']) . '&lang=en';
$out = str_replace('nameS', $name, $html);
$out = str_replace('urlS', $url, $out);

when i set some cron jobs for loading a php file cron doesn't work and it seams some php function have problem with cron job.
i know my cron command is true because i tested my cron job working true with simple php code that put date to a text file so my cron command is true i tested all ways of command like : wget, crul , cd, php , /user/local/bin/php and another but i don't know why my php code doesn't work and too i test that codes working very well when i loading php files with my browser.

I'm using var_export to dump output to logs when errors occur. However since the result is in pure text, I don't get a chance to push it through some sort of library like krumo so I can interactively explores the output.
What methods do people have to deal with making var_export text more readable?
Here is my function, it works well for multidimensional arrays:
function VE($varname, $varval, $short_syntax=true, $tag = ' ', $comma='', $end_line="\r\n") {
$res = '';
if($short_syntax){
$begin_array = '[';
$end_array = ']';
} else {
$begin_array = 'array(';
$end_array = ')';
}
$arr = explode('/',$varname);
$dim =count($arr)-1;
$lastKey = end($arr);
if (! is_array($varval)){
if( is_string($varval)) $varval = "'$varval'";
$res .= str_repeat($tag,$dim) . $lastKey . ' => ' . $varval . $comma . $end_line;
}else{
$res .= str_repeat($tag,$dim) . $lastKey . ' => ' . $begin_array . $end_line;
$count_varval = 0;
$dim_varval = count($varval);
foreach ($varval as $key => $val){
$count_varval++;
if($count_varval<$dim_varval) $commma=','; else $commma='';
if( is_string($key)) $key = "'$key'";
$res .= VE ($varname . "/" . $key , $val, $short_syntax, $tag, $commma);
}
$res .= str_repeat($tag,$dim) . $end_array . $comma . $end_line;
}
return $res;
}
$bigarray = array(); // your array
$bb = VE ('$bigarray', $bigarray);
echo "<pre>$bb</pre>";
I hope it helps ;)
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 to implode foreach() with comma?
foreach($names as $name) {
//do something
echo '' . $name .'';
}
Want to add comma after each link, except the last one.
Raveren's solution is efficient and beautiful, but here is another solution too (which can be useful in similar scenarios):
$elements = array();
foreach($names as $name) {
//do something
$elements[] = '' . $name .'';
}
echo implode(',', $elements);
You need to transform your array instead of iterating using foreach. You can do this with array_map.
PHP 5.3 syntax with closures
echo implode(", ", array_map(function($name) use($url, $title)
{
return '' . $name .'';
}, $names));
Compatible syntaxe before PHP 5.3
function createLinkFromName($name)
{
return '' . $name .'';
}
echo implode(", ", array_map('createLinkFromName', $names));
PHP 5.3 syntax with a better reability
function a_map($array, $function)
{
return array_map($function, $array);
}
echo implode(", ", a_map($names, function($name) use($url, $title)
{
return '' . $name .'';
}));
$first = TRUE;
foreach($names as $name) {
//do something
if(!$first) { echo ', '; }
$first = FALSE;
echo '', $name, '';
}
$s = '';
foreach ($names as $name) {
if ($s) $s .= ', ';
$s .= '' . $name . '';
}
foreach($names as $name) {
//do something
$str .= '' . $name .',';
}
echo substr($str,0,-1);
EDIT:
as the comments point out, this way of doing things is a little error prone if you change the separator (precisely its length) and forget the substr parameter. So use the foreach method unless performance is absolutely critical.
Here is an ugly solution using echo:
$total = (count($names) - 1 );
foreach($names as $i => $name)
{
if($i != $total)
echo '' . $name .', ';
else
echo '' . $name .'';
}
