nested while loop with if statment not working

[pagegen]

Hi guys,

 

I have a double nested loop..

 

The issue here is, if(str_replace(" ", "", $row_dataset['numbers']) == str_replace(" ", "", $tps_num)) {

 

$row_dataset['numbers'] is "01125336538" and  $tps_num is also "01125336538"

but the if statment wont echo what its spose too..

 

 

		while($row_dataset = mysql_fetch_array($result_get_dataset)){

		while($row_tps = mysql_fetch_array($result_get_tps)){
				$test++;
				$tps_num = $row_tps['numbers'];
				if(str_replace(" ", "", $row_dataset['numbers']) == str_replace(" ", "", $tps_num)) {
				$tps_numbers = $tps_numbers . $row_tps['numbers'];
				echo $current_number . " | " . $row_tps['numbers'] . "<br/>";
				}
		}


	}

All help will be usefull guys,

any suggestions at all?

str_replace does not return 1/0 or TRUE/FALSE, it returns the string it work on. So if it does not work as you expected its possible that your string are not ==. Depending on where tps_num comes from perhaps trimming it would help.

Hi

 

I have changed the code

 

	while($row_dataset = mysql_fetch_array($result_get_dataset)){
	$current_number = str_replace(" ", "", $row_dataset['numbers']);


		while($row_tps = mysql_fetch_array($result_get_tps)){
				$test++;
				$tps_num = str_replace(" ", "", $row_tps['numbers']);
				if($current_number == $tps_num) {
					$tps_numbers = $tps_numbers . $row_tps['numbers'];
					echo $current_number . " | " . $row_tps['numbers'] . "<br/>";
					echo "match found";
				}

				echo $current_number . " | " . $row_tps['numbers'] . "<br/>"; 
		}


	}

 

without the if it does echo the both numbers

01125336538 | 01125336538

 

bit with the if, nothing happens..

 

[priti]

you are printing

echo $current_number . " | " . $row_tps['numbers'] . "<br/>";

 

try

echo $current_number . " | " . $tps_num . "<br/>";

Hi, just tried that, no luck

[pagegen]

i have also tried

 

$current_number = "01125336538";

 

if($row_tps['numbers'] == $current_number)

 

no luck with that either..

 

but if I echo $row_tps['numbers']

its the same number...

Change the if comparison to != and see what happens.

01125336538 | 01125336538

 

Can you remove those leading zero and try... It may be possible that these number are internally taken as octal... so either you can cast your these two number in int and then compare.. or just give a try removing those leading zeros.

[pagegen]

	while($row_dataset = mysql_fetch_array($result_get_dataset)){
	$current_number = str_replace(" ", "", $row_dataset['numbers']);
	if ( $current_number{0} == "0" ) $current_number = substr($current_number, 1);

		while($row_tps = mysql_fetch_array($result_get_tps)){
				$test++;
				$tps_num = str_replace(" ", "", $row_tps['numbers']);
				if ( $tps_num{0} == "0" ) $tps_num = substr($tps_num, 1);
				if($current_number == $tps_num) {
					$tps_numbers = $tps_numbers . $row_tps['numbers'];
					echo $current_number . " | " . $tps_num . "<br/>";
					echo "match found";
				}

				echo $current_number . " | " . $tps_num . "<br/>"; 
		}


	}

 

Just removed the 1st character of both

 

when echoed without if()

1125336538 | 1125336538

 

when if used, nothing

Change the if comparison to != and see what happens.

Tried this

if($current_number != $tps_num) {

 

the following is the echo..

1125336538 | 1125336538

match found

Then trim the vars before you use them
