The following php function will return an array(0-10) of image URLs.

<?php
/* Returns 10 image URLs array */
function images_search($se, $kw){
 $icount=0;
 $image =array();
 if($se=="Bing"){
 $imgs = 'http://www.bing.com/images/search?q='.urlencode(trim($kw));
 $imgs = file_get_contents($imgs);
 preg_match_all("/<span class=\"md_mu\">(.*?)<\/span>/is", $imgs, $imgu, PREG_PATTERN_ORDER);

 shuffle($imgu[1]);
 $iv = array_values($imgu[1]);

 for($j=0; $j < count($iv);$j++)
 if(strpos($iv[$j],'"')>-1 || strpos($iv[$j],'""')>-1) continue;
 elseif(@fclose(@fopen($iv[$j], "r"))){  
 $image[$icount]=$iv[$j];
 $icount++;
 if($icount==10)
 break;
 }
 }else{
 $start=rand(0,9)*20+1;
 $imgs= 'http://images.google.com/images?gbv=2&hl=en&q='.urlencode(trim($kw)).'&sa=N&start='.$start.'&ndsp=30';
 $imgs = file_get_contents($imgs);
 preg_match_all("/x3dhttp:(.*?).jpg/is", $imgs, $imgu, PREG_PATTERN_ORDER);

 shuffle($imgu[1]);
 $iv = array_values($imgu[1]);

 for($j=0;$j<count($iv);$j++)
 if(strpos($iv[$j],'"')>-1 || strpos($iv[$j],'""')>-1) continue;
 elseif(@fclose(@fopen('http:'.$iv[$j].'.jpg', "r"))){  
 $image[$icount]='http:'.$iv[$j].'.jpg';
 $icount++;
 if($icount==10)
 break;     
 }
 }
 return $image;
}
?>

Use this function like this:

<?php

// Call function like

$google_images = images_search('Bing', 'doctors');

// or

$bing_images = images_search('Google', 'forex');

?>

There are cases when a php developers need to insert mysql data with strings which containing single or double quotes. Mysql  gives error or will not save data if we do not properly escape the string formation characters. To escape these characters php have a function {mysql_real_escape_string()}. This function can be used to format the mysql strings with escaping. e.g.

<?php

$escaped_mystring = mysql_real_escape_string($mystring);

?>

Now if you run the query after escaping it will save the string wit out any error.

php mysql single double quote problem (1)

In doing a project for backlinks in php, I came across a problem. When a link is saved in database then if user reload the page, the script re-save the data. So I want a solution that on reloading browser the post data should not save. I searched for it but could not find some proper solution. Here is what i did:

<?php
if(!isset($_REQUEST['ok']))
{
  // database query to save post data...
  Header("Location: same_page.php?ok=true");
}
?>

So when you send header on same page but with a request variable which set now this time, it will not allow the query to save same information again. So on hitting reload the form will not submit and you can also stay on the same page.

Note: If you use this method and do not send a request variable, then it will become infinite loop.

Here are some other to try:

Use a meta refresh,

You can also just add a session variable when the form has been submitted successfully. Then on the same time check if the session variable is set before you resubmit the form.

Then it would not matter if the same post data is resubmit, since the session variable would be set.
