PHP - Break Gone Wild

I was wondering if you guys could help me 'break' a function I've been working on. It converts a CSV-formatted string to a 2d array following RFC4180. Here's the function.

/**
 * 
 * Covert a multi-line CSV string into a 2d array. Follows RFC 4180, allows
 * "cells with ""escaped delimiters""" and multi-line enclosed cells
 * It assumes the CSV file is properly formatted, and doesn't check for errors
 * in CSV format.
 * @param string $str The CSV string
 * @param string $d The delimiter between values
 * @param string $e The enclosing character
 * @param bool $crlf Set to true if your CSV file should return carriage return
 *  and line feed (CRLF should be returned according to RFC 4180
 * @return array 
 */
function csv_explode( $str, $d=',', $e='"', $crlf=TRUE ) {
// Convert CRLF to LF, easier to work with in regex
if( $crlf ) $str = str_replace("\r\n","\n",$str);
// Get rid of trailing linebreaks that RFC4180 allows
$str = trim($str);
// Do the dirty work
if ( preg_match_all(
'/(?:
'.$e.'((?:[^'.$e.']|'.$e.$e.')*+)'.$e.'(?:'.$d.'|\n|$)
# match enclose, then match either non-enclose or double-enclose
# zero to infinity times (possesive), then match another enclose,
# followed by a comma, linebreak, or string end
| ####### OR #######
([^'.$d.'\n]*+)(?:['.$d.'\n]|$)
# match anything thats not a comma or linebreak zero to infinity
# times (possesive), then match either a comma or a linebreak or
# string end
)/x', 
$str, $ms, PREG_SET_ORDER
) === FALSE ) return FALSE;
// Initialize vars, $r will hold our return data, $i will track which line we're on
$r = array(); $i = 0;
// Loop through results
foreach( $ms as $m ) {
// If the first group of matches is empty, the cell has no quotes
if( empty($m[1]) )
// Put the CRLF back in if needed
$r[$i][] = ($crlf == TRUE) ? str_replace("\n","\r\n",$m[2]) : $m[2];
else {
// The cell was quoted, so we want to convert any "" back to " and
// any LF back to CRLF, if needed
$r[$i][] = ($crlf == TRUE) ?
str_replace(
array("\n",$e.$e),
array("\r\n",$e),
$m[1]) :
str_replace($e.$e, $e, $m[1]);
}
// If the raw match doesn't have a delimiter, it must be the last in the
// row, so we increment our line count.
if( substr($m[0],-1) != $d )
$i++;
}
// An empty array will exist due to $ being a zero-length match, so remove it
array_pop( $r );
return $r;

}

And to use it:

$csv = 'this,will,"be ""separated""",by
"commas,",,"should work with
""multiline,"",
",entries
some,last,data,"test"';

print_r( csv_explode($csvn) );

or

$csv_eurwin = "this;will;'be ''separated''';by\r\n";
$csv_eurwin .= "'semicolons;';;'should work with\r\n";
$csv_eurwin .= "''multiline;'';';entries\r\n";
$csv_eurwin .= "some;'last';data;'test'";


print_r( csv_explode($csv_eurwin, ';', '\'', TRUE) );

Thanks! Here's the actual spec if anyone cares
Code: [Select]
   1.  Each record is located on a separate line, delimited by a line
       break (CRLF).  For example:

       aaa,bbb,ccc CRLF
       zzz,yyy,xxx CRLF

   2.  The last record in the file may or may not have an ending line
       break.  For example:

       aaa,bbb,ccc CRLF
       zzz,yyy,xxx

   3.  There maybe an optional header line appearing as the first line
       of the file with the same format as normal record lines.  This
       header will contain names corresponding to the fields in the file
       and should contain the same number of fields as the records in
       the rest of the file (the presence or absence of the header line
       should be indicated via the optional "header" parameter of this
       MIME type).  For example:

       field_name,field_name,field_name CRLF
       aaa,bbb,ccc CRLF
       zzz,yyy,xxx CRLF

   4.  Within the header and each record, there may be one or more
       fields, separated by commas.  Each line should contain the same
       number of fields throughout the file.  Spaces are considered part
       of a field and should not be ignored.  The last field in the
       record must not be followed by a comma.  For example:

       aaa,bbb,ccc

   5.  Each field may or may not be enclosed in double quotes (however
       some programs, such as Microsoft Excel, do not use double quotes
       at all).  If fields are not enclosed with double quotes, then
       double quotes may not appear inside the fields.  For example:

       "aaa","bbb","ccc" CRLF
       zzz,yyy,xxx

   6.  Fields containing line breaks (CRLF), double quotes, and commas
       should be enclosed in double-quotes.  For example:

       "aaa","b CRLF
       bb","ccc" CRLF
       zzz,yyy,xxx

   7.  If double-quotes are used to enclose fields, then a double-quote
       appearing inside a field must be escaped by preceding it with
       another double quote.  For example:

       "aaa","b""bb","ccc"

echo '<div class="gamename">'.$values[0].'</div>';
echo  '<div class="gameimage"><a href="'.$values[3].'"><img src="'.$values[1].'"></a></div>';

NOW i want 2nd echo under 1st echo. I tried every single <br> combination but no luck   

Also my 2nd question is: my image and link is a variable, it displays the image but there is something wrong with link.
Variable is just like this  www.mydomain.com\image\blabla.php
but it shows link as==> www.mydomain.com\     instead of what i wrote above.

I have a chain of methods, is there anyway to end the chain half way through if some particular event happens?

Here is an example (not the best but still an example):
Code: [Select]
<?php
$age = $class->post("age")->callback(funciton(){
        global $class;
        if($class->string() < 18){
                // end the execution of the chain, doesn't execute toInt()
        }
})->toInt();
?>

hi
i have some troubles to create a new line break for this code:

i already tried:

Code: [Select]
    echo "<input type='radio' name='gropu1' value='$id'>$data \n ";   
//

  Code: [Select]
   echo "<input type='radio' name='gropu1' value='$id'>$data.\n ";
//
Code: [Select]
    echo "<input type='radio' name='gropu1' value='$id' >$data.'\n'";

what is the correct syntax for that?

I want to have a line break between the lastname and the age. Please help.

echo $line["firstname"].' '.$line["lastname"].' Age is'.$line["age"].'!';

Code: [Select]
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field'].",";
$i++;
}
}
$csv_output .= "\n";

$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}

print $csv_output;
I'm using the above to get a csv output in my browser, but it appears as a string of text
eg
a1,a2,a3,a4,b1,b2,b3,b4,...

I'd like it to appear as
a1,a2,a3,a4
b1,b2,b3,b4
c1,c2,c3,c4

Any ideas how?

How do i get the first part of the string, all the way up until the string hits a line break?

Code: [Select]
<?php
$string = "The quick red fox\n jumped over the brown\n lazy dog.";

function first_of_string($str)
{
//php magic

return $first_of_string;

}

echo first_of_string($string); //would produce "The quick red fox"

?>

 This is my code to connect java socket:-

```

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

socket_connect($socket, '127.0.0.1', 12345);

while(true)

{

    // read a line from the socket

    $line = socket_read($socket, 1024, PHP_NORMAL_READ);

    var_dump($line);

    $someArray = json_decode($line, true);

    $otp = $someArray["otp"];

   if($someArray["msg"] == "otp_generation")

  {

      $myObj = new \stdClass();

      $myObj->msg = "OTP RECEIVED NEED TO CONNECT";

      $send = json_encode($myObj);

      socket_send($socket, $send, strlen($send), 0);

   }

 exit;

}

```

When connection is established successfully server send one OTP to client and received successfully in client. Then i send data to server OTP RECEIVED acknowledgement, it also received in server. After OTP RECEIVED acknowledgement server send welcome msg to client. I cant get the welcome message. if i remove the (exit) soket_write is not working i can't send data to server. if i put exit data send to server successfully and socket is closed. What can i do for this type of issue.

I don't know what mistake i done.?

Add tags

I have print page using window.print in the body tag at the beginning of php file and i am trying to make the rest of the code as second page, the last table will be on the second page. it is not working.

code:

<b>Absent Report:</b>
    <table style ="page-break-before: always;" border='1'>
		
        <tr><th>ID</th><th>Name</th><th>Absent</th></tr>
        <?=$tdata?>
    </table>
	
	<a href="singlereportbyid.php" width="100%">Click here to go back to Main Menu</a>

			</div>
		</div>
	</div>
</div>
</body>
</html>

why it is not working?

Working with authorize.net script that is included in my php.  Trying to figure out how to use a variable beyond the 'case' I can do just about anything... inside the case... But I need to use the variable outside of there.

Code: [Select]
//several cases above
case 5:
$this->approval_code = $pstr_trimmed;
break;

// case 7 is the authorize.net transaction ID - This is the one I want to work with
case 7:
echo "Transaction ID: ";
echo $pstr_trimmed;
$trans_id_test = $pstr_trimmed;

break;
// but this below won't work. I can't use the variable anywhere outside of the case.
echo "the new variable is now...".$trans_id_test;

So I have built a coupon component for Joomla which is working nicely.. However I am very green when it comes to Mysql and PHP more so the MySql part .. any way The user selects coupons adds them to a printing shopping cart so to speak and then prints the coupons.  However 4 coupons print fine to a page but the 5th coupon gets cut in half. I have tried spacing stuff out etc however since CSS is just a recommendation and there is not standard across so many browsers. It is just a mess. I did some googling and saw I can do a page break after so many rows however there is not alot of info on the structure so hoping some one can help.
Here is actually the complete code from the print page.

Code: [Select]
<?php
define('_JEXEC', '1');
include("../../configuration.php");
$config = new JConfig();
$conn = mysql_connect($config->host, $config->user, $config->password) or die("can not connect.");
mysql_select_db($config->db) or die("can not connect.");
$couponIds = implode(",", $_POST['selectCoupon']);
$coupon_footer_text = "";
$query = "select * from joc_other_settings limit 0,1 ";
$res = mysql_query($query );
$row = mysql_fetch_assoc($res);
$coupon_footer_text = $row['coupon_footer_text'];
$query = "select * from joc_logo where status='1' limit 0,1";
$res = mysql_query($query );
$logo = mysql_fetch_assoc($res);
$sql = "select * from joc_coupon c inner join joc_merchant m on c.mer_id=m.mer_id where c.cpn_id in (".$couponIds.")";
$res = mysql_query($sql);
if(mysql_num_rows($res) > 0)
{
while($row = mysql_fetch_assoc($res))
{
$address = $row['address']."<br>".$row['city'].", ".$row['state']."-".$row['zip'];
$logoToShow = ($row['logo']!="")?"images/".$row['logo']:"images/company_logo/".$logo['logo'];
//////////// Begin Coupon /////////////////
?>
<head>
<link rel = "stylesheet" type="text/css" href="/components/com_coupon/print.css" >
</head>
<body>
<div id="box">
<div class="cpntitle"><?=$row['cpn_title']?></div>
<div class="cpndesc"><?=$row['cpn_desc']?></div>
<div class="boxlogo"><img height="75" width="175" src="../../<?=$logoToShow?>"></div>
<br />
<div class="cpnres">Sku: <?=$row['cpn_restriction']?></div>
<div class="cpnexp">Expires On: <?=date("m/d/Y", $row['cpn_expire'])?></div>
<img src="/images/cpimg/coupon_bottom.png">
</div>
<br />
<?php 
/////// End Coupon //////////
}
}
?>

<script type="text/javascript">
window.print();
</script>

I am pretty sure the page break goes in after
Code: [Select]
while($row = mysql_fetch_assoc($res))But the actual structure is killing me. If some one can help me with this I would be great full could even shoot a few bucks over PayPal if you want.

Thanks

Hi,

I'd like to know what the best way of breaking out of a nested foreach loop is..but not breaking out of the first foreach

ears the code like,

Code: [Select]
foreach ($apts as $apt) {

foreach($rdb as $rem)
{
// Check to see if we've already sent a reminder for this appointment
if($apt->id == $rem->appid)
{
    // TODO get out of this foreach and go to the next iterartion of the first foreach
}

}

//rest of 1st foreach code here
}

is there some syntax i can put at the first foreach eg [here] and reference it within the second foreach continue[here]; or something?

thanks,

I'm pretty new to php (as in I suck at it) so please bear with me. I have an entire site within a frame so that the domain name always shows up, without anything after it. Within the site I have a page using the "winxp progress bar" javascript that pops up a java notification and then redirects to another page when the user clicks the "OK" button - when this happens, I'd like to break the frame so that the full URL of the new page is displayed. In HTML this would be target="_top" but I'm not sure how to do it here. Here is the code for the entire page:

Code: [Select]
<html>
 
<head>
<title>Searching</title>
<script language="javascript" src="xp_progress.js">
 
/***********************************************
* WinXP Progress Bar- By Brian Gosselin- http://www.scriptasylum.com/
* Script featured on Dynamic Drive- http://www.dynamicdrive.com
* Please keep this notice intact
***********************************************/
 
</script>
</head>
 
<body bgcolor="white" text="black" link="blue" vlink="purple" alink="red">
<table border="0" width="804" align="center">
    <tr>
        <td width="794" align="center">
<h2 align="center"><font face="Verdana">Searching for  <?php echo $_GET['id'];?>  ...</font></h2>
                   
<p align="center">
<script type="text/javascript">
 
function redirectpage(){
bar3.togglePause()
alert('<?php echo $_GET['id'];?> Found!');
window.location="lp.php"
}
 
var bar3= createBar(400,15,'white',1,'black','green',125,7,2,"redirectpage()");
 
 
 
</script>
</p>
</td>
    </tr>
</table>
</body>
 
</html>
"lp.php" is the final page and the one that should break the frame. I'm not sure whether this should be done inside the redirect on this page, or if it should be done inside lp.php. lp.php is just another redirect (there used to be some more things on it but I took them all out and had too many links pointing to it to bother changing them all). This is the entire contents of lp.php:

Code: [Select]
<?php
   header("Location: http://www.[urlremoved].com");
?>

I'm assuming it would be easier to put the frame break on this page, but I really have no idea. If someone can help me with it I'd really appreciate it.

I'm trying to use SESSIONS, the start of my page looks like this:


<?php session_start();



and the start of the source code looks like this:


<br /> 
<b>Warning</b>:  session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent by 


The <?php tag is on line 1, yet as you can see Notepad++ seems to add a <br /> before it, which results in the sessions not working.

How can I fix this?

so i have this string that i want to search on the database

My database has 3 parts city, state, country

and i have a string that is say "new york city, ny, united states"
