[[SOLVED] My code won't echo my variables!]

I have just realised where the problem likely lies. The entry which contains the variables is showing up in the HTML source, php tags and all. It's saved as a .php file, so this shouldn't happen, should it?

That is because you are reading it like a text file.

you may be better off using "include()" rather than "fread()"

[exec()]

hi all

i have a exe program.when i click and run it ,it works perfectly.

But when i call it using exec() it

got stucked at a point.

 

can anybody help in this matter.

Are you specifying the full path in your call?

Are permissions set on the file to allow php/apache to run it?

Is the file waiting for an input?

[[SOLVED] My code won't echo my variables!]

I have a code that saves some variables to a php file.

Just what are you saving?  (the value of the variable or the name and value of the variable.)

and how are you calling it?

if the variable is not being reset there will be nothing to echo.

max_execution_time = 60    ; Maximum execution time of each script, in seconds

max_input_time = 60 ; Maximum amount of time each script may spend parsing request data

memory_limit = 32M      ; Maximum amount of memory a script may consume (16MB)

That is from my test server, the "memory_limit" is what you need to increase.

 

 

[Sorting A Multi dimensional array]

The way I have handled this in the past is to convert them to a simple array with an "/" as a separator

$x=0;

# start loop1

$new_array1[]="$time..../$ip.../$data.../$etc....";

$x++;

# end loop1

sort($new_array1);

$x=0;

# start loop2

$new_array2=explode("/",$new_array1[$x]);

# use the new array or put it back sorted

$x++;

# end loop2

Unless you have root access to the server you will have to break the file into several smaller files.

[Storing Files]

No, anything above your /www/ directory (on apache) can't be accessed directly.

That will work, as long as the directory is readable by php and you have a directory that is readable and writable by php that can be accessed by apache.

 

I have written such a script for private viewing of screen shots of confidential info.

 

php:

validates the user

creates a randomly named 25 character directory

copy's the file(s) to it.

produces the appropriate web page

flushes the output

waits a preset time then erases the file and directory

[Memory used by your php script]

I could not find the answer in any of the books that I had but

 

http://ca3.php.net/manual-lookup.php?pattern=memory gave me the answers

 

memory_get_usage()

 

memory_get_peak_usage()

[Memory used by your php script]

I am a fairly experienced with php/mysql and have some mission critical scripts I wish to expand but  I don't want to risk breaking them by running out of allocated memory .

 

Is there a command in php that will return the amount memory used by a script or one that returns the amount that is still available ??? 

[deals with simple arrays]

You can use some advanced array functions

$new_array= array_unique($old_array); # get rid of dups
$new_array2= array_diff_assoc($old_array,$new_array); # get only the dups
$keys_old_array= array_keys($new_array2); # keys of dups in old_array other than the first appeance.

Do you mean like this
[code]$never_in_pswd=array(" ","\"","!","@","$","%","^","(",")",":",";",",","|","<",">","=","'");[/code]
Validate like this
[code]$i=0;
while ( $i < strlen($p_word))
{if (in_array($p_word[$i],$never_in_pswd))
    { $e_message="\"$p_word[$i]\" is not allowed in a password";}[/code]
Works for me [img src=\"style_emoticons/[#EMO_DIR#]/smile.gif\" style=\"vertical-align:middle\" emoid=\":smile:\" border=\"0\" alt=\"smile.gif\" /]

mind you there is a more code needed, but that just the part you a looking for
