PHP - Appending Char To An Array Using Count()

Hi,

I have an html page with multiple image tags inside it.

I'm wanting to get the full URL of a specific image within that file.

The specific image I'm looking for must start with 'http://www.mysite.com/images/' in the src part of the tag to make sure I'm getting the correct image.

To find the occurence, I'm using strpos() to find the character position of the string match.

What I then need to do is complete the rest of the URL to get the image name and then output this.

So basically I need to get the string that comes after 'http://www.mysite.com/images/' and end when the speech mark occurs to close the src part of the image tag.

This will then give me the full URL of my image.

How do I do this? Or is there a better way to do this?

Thanks.

Hey all,

I have two objects that contain object instances. I want to compare the properties of the instances and if the old_parent's property doesn't exist as one of the $new_parent's property, then I place the old_parent's property in an array called unneeded_ids. Problem is when I use nested foreach to loop through the instances of the two objects, despite old_parent having only one instance with a property id of 1, because it loops twice, the array gets two "1" values rather than just one:

Code: [Select]
public function update(){
$vanity_url = new VanityUrl();
$vanity_url->where('user_id',$this->current_user()->id)->get();

$zones = $this->input->post('zones');
$zone = new Zone();
$zone->where_in('name', $zones)->get();

$subcategory = new Category();
$subcategory->where('id',$this->uri->segment(4))->get();

$old_parents = new Category();
$old_parents = $subcategory->related_category->get();

$unneeded_ids = array();

if(!$this->input->post('catupload')){
if($subcategory->save($zone->all)){
redirect("blogs/$vanity_url->url/categories");
}
else {
echo "Error occurred. Please try again.";
}
}
else {
$new_parents = new Category();
$controller = $this->input->post('catupload');
$new_parents->where_in('controller',$controller)->get();

foreach($new_parents as $new){
foreach($old_parents as $old){
if($new->id != $old->id){
  array_push($unneeded_ids, $old->id);
  }
}
}
var_dump($unneeded_ids);

}
}

The var_dump outputs:
Code: [Select]
array(4) { [0]=> int(126) [1]=> int(127) [2]=> int(126) [3]=> int(127) }
but it should only output:
Code: [Select]
array(2) {[0]=> int(126) [1]=> int(127)}
That's because there's only one object instance of old_parent that has a property id value of 126 and the same for 127. The nested for each loop is causing it to iterate twice against the same object and sticking it into the array. How do I get desired result?

Thanks for response.

Hi, can anyone help me with this.

I have a column in my table call "machine", I want to count the number of time each appears and return the results into an array

In the example below the number of times each printer appears in the column is returned to the array


____________
machine
____________
fb7500-1
fb7500-2
turbojet
turbojet
xl1500-1
xl1500-2
canon
roland

When I run the following I get the names as well as the values and I just want the values??

Result like this

Canon   1
FB7500-1   1
Roland   1
TurboJet   2
Vutek QS3200   1
XL1500-1   1

Code: [Select]
<?php
mysql_connect("localhost","XX","XX");
@mysql_select_db("schedule") or die( "Unable to select database");

date_default_timezone_set('Europe/London');

$query = "SELECT machine, COUNT(machine) FROM maindata GROUP BY machine"; 

 
$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){

$array = array( 'key1' => $row[0], 'key2' => $row[1],'key3' => $row[2],'key4' => $row[3], 'key5' => $row[4],'key6' => $row[5],'key7' => $row[6]);
extract($array);
echo "$key1<br>$key2<br>$key3<br>$key4<br>$key5<br>$key6<br>$key7";

}
?>

I have the following array:

Code: [Select]
Array ( [item0] => Array ( [0] => name1
                                         [1] => name2
                                         [2] => name3
                                         [3] => name4
                                         [4] => name5 )etc...

Is it possible to count the number of times a name exists in the compleet array?

Thanx in advance!

Code: [Select]
$LinksText = array();
    for ($i=0; ($i < $cnt && $i < $total); $i++ ) {
                $Text = explode ('#', $Links[$i]);
                $LinksText[]=$Text[1];
        }
$count = count($LinksText);
print_r(LinksText);
        print count($LinksText);

if($count > 0){
echo "I am not zero"
}
else {
echo "I am zero"
}

Code: [Select]
output:

Array ( [0] => [1] => ) 2


Please tell me why the array count is 2.
