    [SOLVED] Problem using while() to get unique number

    in PHP Coding Help

    Posted

    maybe its just sleepless nights trying to get this thing working...

    i made the change "$result[$i] to $arr[$i]"

    and only 1 number came out instead of 6 numbers...

    <?
error_reporting(E_ALL);
ini_set('display_errors', 1);

$arr = array();
$i=0;
$result = array();

while ( count($arr) < 6 ) {
    $x = mt_rand(1,10);
    if ( !in_array($x,$arr) ) {
	$arr[$i] = $x;
	$i+=1;
}
}
print_r($x);
?>

    :confused:::)

    [SOLVED] Problem using while() to get unique number

    Posted

    hi all,

     

    I've been trying to source for script to produce unique for digit number as in getting php to randomise 4 digits with no digit having same value.

     

    So i tried this code i got from

    http://forums.digitalpoint.com/showthread.php?t=9048

    and modified it a bit into:

    <?
error_reporting(E_ALL);
ini_set('display_errors', 1);

$arr = array();
$i=0;
$result = array();

while ( count($arr) < 6 ) {
    $x = mt_rand(1,10);
    if ( !in_array($x,$arr) ) {
	$result[$i] = $x;
	$i+=1;
}
}
print_r($x);
?>

    This is the output that i got:

    Fatal error: Maximum execution time of 30 seconds exceeded in D:\Apache Group\Apache2\htdocs\..... on line 11

    Any suggestions?

    Hi there,

     

    I'm trying to do a function to get the values of $hour_1,$min_1,$hour_name and $min_name.

    Can anyone help me see what went wrong?

    <? php
function min2hrmin($hour_1,$min_1,$hour_name,$min_name){

$min = rand(60,999);
//echo $min.'<br>';
$hour = $min / 60;

$hour_1 = floor($min / 60);
	  //Sorting Singular and plural form
	  if($hour_1 < 1){
		  $hour_name = 'hour';
	  }
	  else{
		  $hour_name = 'hours';
	  }

$min_1 = $min % 60;
	  //Sorting Singular and plural form
	  if($min_1 < 1){
		  $min_name = 'minute';
	  }
	  else{
		  $min_name = 'minutes';
	  }
return ($hour_1,$min_1,$hour_name,$min_name);	  
} 
echo $hour.'<br>';
echo $min.'<br>';
echo $hour_1.'<br>';
echo $min_1.'<br>';
echo $hour_name.'<br>';
echo $min_name.'<br>';
?>

    [SOLVED] Alternatives to do() function

    in PHP Coding Help

    Posted

    Hi there,

    I try to control the output of this code:

    $multiplier = rand(2,7);

//Get value of second volume via $multiplier
//Making sure value of second volume is not greater than 10,000 to control array only up to 4

do {
$lml_2 = $lml_1 * $multiplier;
} while ($lml_2 > 10000);

    and i get this error:

    Fatal error: Maximum execution time of 30 seconds exceeded in volume02.php on line 26

    Is there any alternative to the do() while() function?

    preg_replace confusion

    in PHP Coding Help

    Posted

    Your regex does not match against an expression, only a simple pattern, you can use either of these:

    function br2nl($text) {   
      return preg_replace('/<br\\s*?\/??>/i', '', $text);
}
br2nl($sub); //Using a function

echo  preg_replace('/<br\\s*?\/??>/i', '', $sub); //Directly

    What do u mean my regex doesn't match the expression i thought it clearly state the exact match i want to find and change them specifically. Please do explain. I'm still pretty new to PHP and any explanation that could assist my transition into a better understanding will definitely be of great help. For instance what is regex? I google it but could not understand heads or tails. Apparently there's a lot of problem with regex.

    preg_replace confusion

    in PHP Coding Help

    Posted

    Hi all,

    I'm trying to replace certain characters i pulled from database using preg_replace.

    <?
$patterns[0] = '<br />';
$replacements[0] = "\n";
echo preg_replace($patterns, $replacements, $sub);?>
?>

    Resulting output:

    Theme 1: Science and Technology<
>
Chapter 1	Introducing Science <
>
Theme 2: Measurement<
>
Chapter 2	Measurement and Units<
>
etc.

    What i don't understand is why there's "<" and ">" still reflected on the output?

    Jargons in array... Pls help explain

    in Regex Help

    i saw this weird looking example when trying to learn preg_replace() function:

    <?php
$patterns = array ('/(19|20)(\d{2})-(\d{1,2})-(\d{1,2})/',
                   '/^\s*{(\w+)}\s*=/');
$replace = array ('\3/\4/\1\2', '$\1 =');
echo preg_replace($patterns, $replace, '{startDate} = 1999-5-27');

?>

    Output:

    5/27/1999

    Can anyone pls explain what the jargons in $pattern and $replace means?

     

    [SOLVED] Apostrophes and <br>

    in PHP Coding Help

    Posted

    I have a mix of both <br> and apostrophes in my multiline form entry that i need to send to MySQL BLOB. When i searched online i found that i can use str_replace(). When i tried coding it i realise i can only use it only for either <br> or apostrophe not both.

     

    I tried using mysql_real_escape_string() but nothing was sent to database.

    Below is my current stable script only replacing <br> with "/n". How do i add apostrophe string replace?

    //$challenge=$_POST['challenge'];
$challenge = str_replace("\n","<br>",$_POST['challenge']);
//$solutions=$_POST['solutions'];
$solutions = str_replace("\n","<br>",$_POST['solutions']);
//$remarks=$_POST['remarks'];
$remarks = str_replace("\n","<br>",$_POST['remarks']);

     

    Thanx in advance...

    [SOLVED] Parsing HTML from PHP...

    Hi guys,

    I'm trying to parse HTML form from PHP. Can anyone please tell me what could've gone wrong?

     

    output .= "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">";
output .= "<html xmlns=\"http://www.w3.org/1999/xhtml\">";

output .= "<link href=\"jjrq.css\" rel=\"stylesheet\" type=\"text/css\" />";
output .= "</head>";
output .= "<body>";
output .= "<form action=\"\" method=\"post\" name=\"table\" id=\"table\">";
output .= "<select name=\"select\" id=\"select\">";
output .= "<option value=\"one\">1</option>";
output .= "<option value=\"two\">2</option>";

    [SOLVED] Count within Array

    in PHP Coding Help

    Posted

    I believe this will do what you're looking for:

     

    $output_counts = array();

for($x1 = 0; $x1 < $lebar; $x1++){
$x1 = $x1 + 30;
$a = array( '#FFFFFF', '#666666');
$a1 = $a[array_rand($a)];

$output_counts[$a1]++;	
}

print_r($output_counts);

     

    That's exactly what i am looking for but how do i store these results into different variable?

    eg; i want to store

     

    $color1 = count '#FFFFFF';

    $color2 = count '#666666';

     

    Thanx again patrick
