    regular expression pattern

    in PHP Coding Help

    Posted · Edited by arunpatal

    Hello,

     

    I have a file to display

    $file_content = file_get_contents("test.php");

    This file is encoded....

    In this file there is a specific tag call change_me

    <change_me> 
"<code> <strong>Example Element</strong> </code>"
 </change_me>

    I want to use htmlspecialchars_decode function for <change_me> tag only...

    <change_me> tag is used two times in file.

     

     

    Thanks

    Because you are using single quotes for denoting the textarea id. Change your single quotes to double quotes instead

    $string = "";
$string  .= "<textarea id=\"convert\"> 'AA' </textarea>";
$string  .= "<textarea id=\"convert\"> 'BB' </textarea>";
$string  .= "<textarea id=\"not_convert\"> 'CC' </textarea>";
$string  .= "<textarea id=\"not_convert\"> 'DD' </textarea>";

    Thanks..  its working

    After you have defined the  $string variable.

    $string = "";
$string  .= "<textarea id='convert'> 'AA' </textarea>";
$string  .= "<textarea id='convert'> 'BB' </textarea>";
$string  .= "<textarea id='not_convert'> 'CC' </textarea>";
$string  .= "<textarea id='not_convert'> 'DD' </textarea>";


$string = preg_replace_callback('/(<textarea id="convert">)(.*?)(<\/textarea>)/is'

                                    ,function($m) {
                                        array_shift($m);
                                        $m[1] = str_replace('AA', 'ZZ', $m[1]);
                                        return implode($m);
                                    }

                                ,$string);

echo $string;

    I tried this way but its not working....

    Could try this if your using PHP 5.3.0 or newer

    $string = preg_replace_callback('/(<textarea id="convert">)(.*?)(<\/textarea>)/is'

                                    ,function($m) {
                                        array_shift($m);
                                        $m[1] = str_replace('AA', 'ZZ', $m[1]);
                                        return implode($m);
                                    }

                                ,$string);

echo $string;

    If the textareas always look the same, you could use str_replace():

    http://www.php.net//manual/en/function.str-replace.php

     

    str_replace() will not solve the problem...

     

    i can change textarea a bit if its requeired but lets say if string is like this and i want to change all AA to ZZ

    <?php

$string = "";
$string  .= '<textarea id="convert"> "AA"  KAA="AA"  $AA</textarea>';
$string  .= "<textarea id='convert'> 'BB' </textarea>";
$string  .= "<textarea id='not_convert'> 'AA' </textarea>";
$string  .= "<textarea id='not_convert'> 'DD' </textarea>";

?>

    Hello everyone,

     

    example string

    <?php

$string = "";
$string  .= "<textarea id='convert'> 'AA' </textarea>";
$string  .= "<textarea id='convert'> 'BB' </textarea>";
$string  .= "<textarea id='not_convert'> 'AA' </textarea>";
$string  .= "<textarea id='not_convert'> 'DD' </textarea>";

?>

    I want to change 'AA' to 'ZZ' which is inside textarea with the id convert only.

     

    How is it possible with the help of regular expression?

    Hi,

     

    I use mysql_escape_string to insert data into my database......

     

    example: $name  = mysql_escape_string($_POST["name"]); $lname  = mysql_escape_string($_POST["lname"]);

     

    mysql_query(INSERT INTO table (fname,lname) VALUES ('$fname','$lname'));

     

    But i am not sure if this is safe enough to protect from mysql injuction....

     

    My question is if it's safe to insert data like this?????

    Repeating month

    in PHP Coding Help

    Posted

    Hi,

     

    This is month (example november)

    $month = date('m');

    This is month + 1 (example december)

    $month = date('m') + 1;

    Now  adding + 2 shows 13

    $month = date('m') + 2;

    This is orignal code

    if($month == 13):

$month = sprintf("%02s", 1);
$year++;

endif;

    It make 13 into 1 but then it repeats again from 14

     

    13 becomes 1

    then 14 stays 14

     

    how can i make month start from 1 till 12 with the help of loop....

     

    ofcourse one bad solution is that i doi it with if statement like

    if ($month == 14){$month = 2}
if ($month == 15){$month = 3}

    Is there a way to do it via loop ???

	 $(".img_div").click(function(){
	 var element_value = $(this).val();
	$("#main_div").css({"background-color":element_value});
  });
});
</script>

    But when i want to change property itself (background-color), its not working

    <script>
$(document).ready(function(){	 
	 $(".img_div").click(function(){
	 var element_prop = $(this).val();
	$("#main_div").css({element_prop:"black"});
  });
