[PHP] fgets function for very large files
hi all, I have a csv file with more than 100,000 lines. I want to insert each line as a record in a database. but for the reason of very number of lines, I put a button with caption Next, when we click on it, 1000 line will insert into db and then again click next button and insert next 1000 line and is this good way? what do you recommend? and how can I do that? Thanks in advance, shahrzad
Re: [PHP] fgets function for very large files
one thing! I need four fields of 7 fields in each line, in my code from original csv file first four of fields choose(mappping these fields with columns of table in db) for example: a line in csv file: a,b,c,d,e,f,g in table of database 4 column : name,ext,tel,date that 4 field of csv file must map to these column then I can't directly import my csv file into db. some process must do to insert just my selected fields of csv file...

Re: [PHP] fgets function for very large files
i accept the fact that PMA is full of security holes, and it should not be used on production server. but it does not mean that we can never use it on a development server probably you may have a bit of trouble while moving from development server to production server. but u can always export your database to an .sql file and import it into production server... but if u dont have access to mysql command line(which is the case in nearly all of the projects i worked on), PMA will probably be the only option...(unless u want to rewrite the entire PMA code.) and certainly http://www.tech-recipes.com/rx/2345/import_csv_file_directly_into_mysql/ is best option for file with 5000 lines..(but you may hav to prefer PMA if mysql is not in your PATH env var) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For example if you have main.php, which is a form whose action is directed to function.php. Function.php process the information from main.php then displays the result. This can take roughly 6 seconds or more. Is it possible to create an intermediary page which alerts the user that the his/her request is being processed in few seconds, then ultimately redirects to function.php (display results). Any idea shall be appreciated. Thanks. Moses Moses: Two things: 1. Anytime the user has to wait, provide a notice of what's happening, such as wait gif to let them know something is happening. Here are some examples: http://webbytedd.com/bb/wait/ 2. Why two scripts? Why not just create a single script? I often have a single script that simply submits forms to itself and evaluates the contents. If the contents pass inspection, then the script moves on to the next step. If not, then the script shows the user where the problem is and ask for the user to fill the form out correctly. I often couple this with javascript to provide more immediate interaction with the user, such as checking proper email format, password and password-confirmation being equal, input required fields, and other client-side stuff. This helps with preparing the data before submission. But I ultimately check and validate all incoming data server-side before doing anything important with it. There's no rule that says everything must be done in separate pages/scripts. Consider this, use a $step variable and set the initial value to 0. Drop the user into the first form and use a input type='hidden' name='step' value='1' within that form. When the user clicks submit, then $step = $_POST['step'] will equal 1 and process the data submitted via a switch or if statement. If everything is Okay, then continue to the next part. If not, then set $step=0 and start over again. Some of my forms have up to ten steps and that's the way I do it.

Where di you hear that output buffers are expensive? I have found the
following:
?php
ob_start();
for( $i = 0; $i 1000; $i++ )
{
echo 'blaah';
}
$foo = ob_get_contents();
ob_end_clean();
?
To consistently be faster than the following:
?php
for( $i = 0; $i 1000; $i++ )
{
$foo .= 'blaah';
}
?
However, if I do the following:
?php
for( $i = 0; $i 1000; $i++ )
{
ob_start();
echo 'blaah';
$foo .= ob_get_contents();
ob_end_clean();
}
?
The run-time is approximately 3 times slower... not exactly expensive
considering it incorporates the concatenation as well as the output
buffering.

an output buffer to capture a value from a call to eval compared to
simply returning the value from the eval'd code.

You should have connected your phrasing to context then. Your wording

other information you provided in the same sentence... relatively
expensive to what? It was in the first sentence, before you introduced
information about returning directly from the eval statement.

The fix is simply to use a different name for the variable, such as: $my_var = $_SESSION['myvar']; I'm just guessing but I'd say this has to do with the way superglobals are created. Since 5.0.0 a configuration option called auto_globals_jit has existed and it defaults to being on. It causes the creation of superglobals to be delayed until they are actually used. I don't know how it interacts with register_globals (the manual says it'll be disabled if register_globals is on) but it makes sense to me that this issue is related to that. I'd say you've found a bug, but you'll need a repeatable example before you can report it. -Stuart -Stuart: I'm pretty sure it's a bug -- all of my scripts work and one doesn't within the same environment. I have a routine where an Administrator can bypass the logon procedures of a registered user to the site and see what the user sees. To do that I simply use a bypass session variable namely: $bypass = $_SESSION['bypass']; I use this exact same statement in 13 different scripts and it works. However, in one script, I have to change the statement to: $by_pass = $_SESSION['bypass']; to make it work. Otherwise it fails with some vague error code about using something that has been depreciated. Considering that the error is surrounded by so much code, I don't want to wade through it all and find the exact problem and report it. Instead, I'm just saying if someone runs into this problem like this, they might try changing the variable name. It's a simple fix, but it's hard to identify.

But, I guess they were lacking some insight there. Instead we got a CSS spec to support table layouts that depended on the asshats over at Microsoft adding support, required all browsers at the time be upgraded, and today is pretty much useless in a global perspective. I'm all for standards, we could have even overlapped this system with CSS support so that when the browser support ultimately came, the switch would be simple. But no, simplicity would have been far too easy for everyone to swallow. Rob: Ain't that the truth. On one side, people who had very little programming skills took advantage of the HTML language through WYSIWYG editors and created something that solved their needs. On the other side, the same people who didn't foresee the problem when they created the language ignores the obvious need for layout and then further complicates the issue by redefining tables and requiring a css solution. They could have easily sought a simple solution such as what you suggested. I often think there should be a grid of some sort to allow people to construct a layout without having to consider the more problematic css positioning and float rules. What better solves that layout problem than a table? Opportunities lost.

I guess you mean GET parameters instead of POST.
$string = preg_replace('/^(.*?)id=/', 'id=', $_SERVER['QUERY_STRING']);

Hi all.
We have done quite a few projects and we are looking to find better ways
to
implementing forms.
Forms seem to be quite time consuming and repetitive.
Generally are there any classes or libraries that will assist with:
1. Easy creation of forms (fields and layout)
2. Validation of specific fields within the forms (server side not JS)
3. Decrease in time required to setup the forms pages
any other comments are welcome.

Dynamic Web and Mobile Solutions
Personally I created a little Class that handles it.
First I create an array of associative arrays, every associative array
represents an input of an abstract type (similar to the webforms, meaning
i have stuff like type=telephone).
Stuff like
$inputs[]=array(
name = foobar,
required = true,
type = string, // text is reserved to textarea
label = Foo Bar,
error_required = you need to provide a Foo Bar value, dummy,
group = main
);
etc.
Then I create an array for groups.
$group[main] = array(
type = block, // types are either block which means div, set which
means fieldset, paragraph which means p or a raw html opening tag.
parent = NULL //optional of course, if set to the name of another group,
then the group becomes a child of the referenced group.
)
Then I create an associative array of options for the form.
Finally, I call the class constructor with the three arrays as params.
The class provides me with a few nifty functions:
* toHtml();
(do I need to explain?)
* toArray();
Returns the inputs, options, and groups inside a single array, with the
value altered when necessary
* wasSubmitted();
Does some guesswork to see if the form was submitted, there's a lot of
smart automagicness inside.
* runAutoChecks();
Runs the checks he can, like the validity of emails in 'type' = 'email'
inputs, pattern validation for input with a set pattern, required inputs,
fills the error array with error messages, sets class[]='error' to wrongly
filled inputs...
* wasValidInput();
Returns true if none of the autochecks or eventual manual checks returned
an error.
And it works like this:
[...]
if ($form-wasSubmitted()){
$form-runAutoChecks();
/* Additional non-automatable controls */
// None in this case
if ($form-wasValidInput()){
// success, do stuff
} else {
// show errors and form again
}
} else {
echo $form-toHtml();
}
There are other things I didn't list, like the fact that ever input has
options to specify a wrapper (class and id are associated to the wrapper
if it's defined), the form encoding automatically changes in case of a
file input, etc etc etc...
The types are abstracted enough that one could easily make a function that
automatically creates the code for a first draft of the forum out of the
db schema of an eventual table. Of course you'd have to provide error
messages, remove unnecessary inputs, adding new ones...
Your ideas are similar to mine, but I have a much more advanced
implementation which involves the use of a Data Dictionary. After building a
database table I import the structure into my data dictionary, then export
it to create a database table class and a table structure file. Still using
the data dictionary I can then build the family of transactions to maintain
that database table. This uses a standard set of page controllers and XSL
templates to build the HTML. So within 5 minutes I can run the transactions
to list, search, add, enquire, delete and update that database table without
having to write a single line of SQL or HTML. In most cases I don't even
have to write a single line of PHP. Is your method as fast as that?
All this functionality exists within the Radicore framework, so you can
download it and try it for yourself.

Re: [PHP] how to delete part of string
What are you trying to do that $_POST can't do? With those duplicate
'id' fields, change the input name to 'id[]' in the HTML form and PHP
will generate an array for you accessible by $_POST['id'][$index]. If
you still have a good reason for working with the raw POST data, just
apply the preg_replace code Marc gave to the content you retrieve from
php://input.
