[PHP] Problem with the passthru function
Hello All, I have a small php file (test.php) whose code is shown below: ?php $retval=1; $command='/bin/ls'; passthru($command, $retval); print(Exit status: . $retval); ? This test.php works fine when I execute from command prompt as php test.php, but when I access it through web browser, it seems not to be working fine, I get an exit status of 127 (which means command not found). I checked for permissions of ls, gave full path, but still it is failing. Can anybody help me in indentifying what is the potential problem? Thank you, Venkatesh ps: Sorry if this is the wrong mailing list. I have subscribed to this list, so posting here. __ Do You Yahoo!? Tired of spam? Yahoo!

[PHP] mysql table row updation based on user input.
Hi,
i have a form for the user input with checkboxes and table rows for the user.
The user can select the checkboxes which correspond to table rows in database.
Depending on the selection of checkboxes i want to update the fields. For
example:
checkboxessubstrate_typesubstrate_numpixelprocess_classprocess_logoperatorcdatectimelocationdurationtemperaturepressureultrasonicsolventpedotsolutionsolution_tempsubstrate_tempmaskcomment
[input] S4350absorber annealingMM2017-09-0514:18:15LF02124000fdsg [input]
M2340pedot annealingMM-00-0014:22:03LF01223000saddDate*: [input]
(DD.MM.YY)
Time*: [input] (HH:MM:SS)
[input]
if the user selects some checkboxes and submits, then i want to take the
cdate,ctime in table and calculate the difference from the current date and
time,and enter the difference in duration.
The code for the above form is
echo 'link rel=stylesheet type=text/css href=sql-query.css';
$link = mysql_connect('localhost', 'root', '');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db('fmfgui', $link);
if (!$db_selected) {
die ('Can\'t use fmfgui : ' . mysql_error());
}
$res = mysql_query(select * from running_processes);
if (!$res) {
print p style=\color:red;\mysql error: .mysql_error()./p\n;}
$ncols = mysql_num_fields($res);
print TABLE style='border: 1pt solid blue; border-collapse: collapse;
cell-spacing: 0px';
print TR;
print TD style='border-bottom-style: double; border-left: 1pt solid
black; font-weight:bold; text-align:center'checkboxes/TD;
for ( $i = 0; $i $ncols; $i++ ) {
$column_name = mysql_field_name($res,$i);
print TD style='border-bottom-style: double; border-left: 1pt
solid black; font-weight:bold; text-align:center'$column_name/TD;
}
print /TR;
print TR;
while ($row = mysql_fetch_array($res)) {
$ncols = mysql_num_fields($res);
print TD style='border: 1pt solid black cell-padding: 3px'input
type='checkbox' name=\id[]\ value=\.$row[id].\ /TD;
for ( $i = 0; $i $ncols; $i++ ) {
print TD style='border: 1pt solid black cell-padding:
3px'$row[$i]/TD;
}
print /TR;
}
print /TABLE\n;
$tdate=date(d.m.y);
echo h4Date*:input type='text' name='edate' value='$tdate';echo
(DD.MM.YY);
echo br /;
$ttime=$ttime = date(H:i:s);
echo h4Time*:input type='text' name='etime' value='$ttime'; echo
(HH:MM:SS);
echo br /;
echo br /;
echo input type='submit' name='submit' value='submit';
echo /form;
The problem is if the user selects more than one checkbox then how can i write
the update command.
thanks
babu.

Re: [PHP] whats wrong in this program.
Hi,
I tried to use the final array values in a insert statement, but the values are
not inserted.
the code is
foreach ($final as $subnum){
$res = $db-query(INSERT INTO
substrate_protocoll(substrate_type,substrate_num,operator,location,solvent,ultrasonic,duration,cdate,ctime,comment)
VALUES('$substrate_type1',$subnum,'$operator','$location','$solvent',$uv,$duration,'$cdate','$sctime','$comment'));
if(!$res){
echo insert failed;
}
}
the values of array ($subnum)are not inserted , can you tell me where the
problem is.

I think I finally understand what you are trying to do. I don't see
any reason why you need to use the token functions, and I would
recommend using array functions instead (also, it is exceedingly easy
to sort the elements of an array... see the end).
I believe this will do what you are trying to do:
//Tokenizer for Babu
$str = '10,12,14-18';
$commas = explode(',', $str); // $commas will be an array of three
items in this case
// Final Values will go into the $final array
$final = array();
foreach ($commas as $value) {
// If one of the $commas elements contains a dash, we need to
get the range between them!
if (strstr($value, '-')) {
// Explode based on the dash. This code assumes there will
only be a single dash
$rangeValues = explode('-', $value);
foreach (range($rangeValues[0], $rangeValues[1]) as $number) {
$final[] = $number;
}
} else {
// If $value does not contain a dash, add it directly to the
$final array
$final[] = $value;
}
}
echo All your values in the range $str are .implode(' ', $final);
// Prints All your values in the range 10,12,14-18 are 10 12 14 15
16 17 18
In your last email, you had some of the values given out of order:
1. 20,21-24
2. 21-24,20
3. 10,20,21-24,25,26,30
To make sure the $final values are always ascending, just do this at
the end:
sort($final);
Done!!

So your block would read:

INTENSITAET=1000.00
DATUM=03.01.2005

correct???
I would do the following:
$filename=myfile.txt;
$target=myfile2.txt;
$handle = fopen ($filename, r);
while (!feof ($handle)) {
$buffer = fgets($handle, 8192);
if (substr($buffer,0,1)!=='[' substr($buffer,0,3)!=='TYP'){
$hf = fopen($target, 'a');
fwrite($hf, $buffer);
fclose($hf);
}
}
fclose ($handle);
That should do the trick.

Re: [PHP] searching for files in a directory with a specific structure.
thanks the format works,
i have written some code for deleting some lines from the above obtained
files,i have used like keyword match for deleting lines from the above
files.the keywords are in the array.
can u pls look at the code and check where goes wrong.
?
$del_lines=array([,TYP,P_MPP,I_MPP,V_MPP,T=,FIT,INTENSITAET);
$dir=getcwd();
$handle = opendir($dir);
while (false !== ($file = readdir($handle))) {
if ((preg_match('/^2005\d{4}_\d{4}\.txt$/',
$file))||(preg_match('/^2005\d{4}_\d{4}\_01_01\.txt$/',$file))){
$fc=file($file); // for reading
$f=fopen($file,w); // for writing.
foreach($fc as $line){
for($i=0;$isizeof($del_lines);$i++){

Check out http://php.net/glob. This might not be the best way to do it
if you have *lots* of files since it returns all matches in an array.
A regex to match might look something like \d\d\d\d\d\d\-\d\d\d\d\.txt
but I'm no regex expert.

[PHP] database querying form in php
HI, I ilke to create user interface for a group of people for entering the queries and to see the results in a browser. The users have the knowledge of database. for example: the users will have a login check, and if successful they will see a window where they can enter the sql queries and can see the results.I also want to implement a history of queries where the user can use it when ever needed. i have done the user authentication part. But i do not get an idea how the User interface can be?

If I understand your question, you are wanting to change the text
colour of an option item...
Do this with css classes...
Cheers
}//foreach

Re: [PHP] change the font color of a string variable in PHP
Hi chris,
i am using mssql and php, so i trying to get the query result when the user
enters the query and submits the execute button.
i want to differentiate the syntactically correct query and the incorrect query
with differ colors.
here i am posting my code
if (-1 == $connection)
$result = mssql_query($query);// or die(Fehler beim Schreiben
in die Datenbank);
else
$result = mssql_query($query, $connection);// or die(Fehler
beim Schreiben in die Datenbank);
if (!$result) {
print p style=\color:red;\MS-SQL-Fehler:
.mssql_get_last_message()./p\n;
$error=1; //my changes}
what i am trying to do is intialising a global variable $error=0 and changing
it to 1 if error occurs.
when displaying i am writing like this
foreach($_SESSION['history'] as $item) {
$item = str_replace(;,,$item);
if(error==0)
echo option $item/option;
else
echo option style=\color: red;\$item/option;
but it doe not work can you pls tell me.
