I have a table "testtable" in MySQL
col1 = id //primary key
col2 = text
<?php //test.php .. $result = mysql_query("SELECT * FROM testtable"); if($result) { //What code shall I write to delete empty text associated with any id ?> -
Seanlim: you are best
I regularly have concerns...will look forward for your help in future!!
-
Again, what I'm asking for is the structure of `table` and `trendingtopics`.
table name = trendingtopics
col1 = topicid //I assigned the id 1 to 10 (hard coded)
col2 = topic //These 10 topics should be updated which are present in $ttopics[]
P.S: We are not getting topicid from that api.
-
You are correct ttopics[] = array () //it holds the strings $ttopics[] = "topic1"; $ttopics[] = "topic2"; .... $ttkey should hold the key in the array:0 to 9 How do we do it?
Ok, maybe I've assumed the structure of your $ttopics array wrongly.
Is it declared something like this?
$ttopics = array(); $ttopics[] = "topic1"; $ttopics[] = "topic2"; ...
If so, $ttkey should hold the key in the array:0 to 9 within the foreach loop. $topic will hold the topic itself.
"something wrong" isn't very helpful. What error do you get/what problem are you facing? Try "or die(mysql_error)" next to the mysql queries also

seanlim: Please help....I am stuck here
-
<?php
require_once("includes/connection.php");
$json = file_get_contents('http://some_api'); Some api I am retrieving the names
$data = json_decode($json);
$ttopics = array();
foreach ($data->trends as $trend)
{
$ttopics[] = $trend->name ; those names I am storing in array
}
foreach ($ttopics as $ttkey=>$topic){ for each array entry as $ttkey
$result = mysql_query("SELECT topicid, topic FROM table WHERE topicid='{$ttkey}'");
if($result)
{
$num = mysql_num_rows( $result );
if ($num == 0)
{
$querypost = mysql_query ("INSERT INTO trendingtopics VALUES ('$ttkey', '$topic')");
}
else{
$row = mysql_fetch_array($result);
if($row['topic']!=$topic)
$querypost = mysql_query ("UPDATE trendingtopics SET topic = '$topic' WHERE topic='$ttkey'");
}
}
}
?>
the topics(ttkey) are not inserting.
-
current table hard coded entry
topicid ------topic
---------------------
1-------------a
2 -------------b

10 -------------j
//I have to update this table with strings present in $ttkey
<?php
...
foreach ($ttopics as $ttkey=>$topic){ $ttkey has the topics (10 strings). These need to be updated instead of a,b ...j
$result = mysql_query("SELECT topicid, topic FROM table WHERE topicid='{$ttkey}'");
if($result)
{
$num = mysql_num_rows( $result );
if ($num == 0)

$row = mysql_fetch_array($result);
if($row['topic']!=$topic)
$querypost = mysql_query ("UPDATE trendingtopics SET topic = '$topic' WHERE topicid='$ttkey'");

<?
There is something wrong in my syntax. Please help

//I am still not able to update
<?php
...
foreach ($ttopics as $ttkey=>$topic){ ttkey has the topics (strings)
$result = mysql_query("SELECT topicid, topic FROM table WHERE topicid='{$ttkey}'"); Then why are checking for "topicid" nstead of topics
if($result)
{
$num = mysql_num_rows( $result );
if ($num == 0)
{
$querypost = mysql_query ("INSERT INTO trendingtopics VALUES ('$ttkey', '$topic')");
}
else{
$row = mysql_fetch_array($result);
if($row['topic']!=$topic)
$querypost = mysql_query ("UPDATE trendingtopics SET topic = '$topic' WHERE topicid='$ttkey'");
}
<?

Please help
-
My "topics" table contains 10 entires
*--------------*
topicid topic
------
*--------------*
01 Bye
02 Hi
03 Hello
.....
10 Morning
*--------------*
<?php //topics.php
require_once("includes/connection.php");
....
....
ttopics[]= //I have 10 strings here which have changed by now.
foreach ($ttopics as $ttkey)
{
//I am trying to update my "topics" table whenever these strings change, based on the topicid (primary key).
//Please correct my code.
$id = mysql_real_escape_string('topicid');
$topic = mysql_real_escape_string('topic');
$result = mysql_query("SELECT topicid, topic FROM table WHERE topicid='{$id}' and topic='{$topic}' ");
if($result)
{
$num = mysql_num_rows( $result );
if ($num == 0)
{
$querypost = mysql_query ("INSERT INTO trendingtopics (topic) VALUES ('$ttkey')");
}
}
I am getting an error. Lets say the position of Morning is first and Bye is last. It should update the database accordingly. If there is a new entry, say "phpfreaks" in first position. It should update according.

Thanks but how do I run it for the first time?
<?php //This is my code I want to run every hour.
$lastRun = time();
if ($lastRun + 3600 < time())
{
runIt();
$json = file_get_contents('http://some_api');
$data = json_decode($json);
$ttopics = array();
foreach ($data->trends as $trend)
{
$tt[] = $trend->name ;
}
foreach ($tt as $ttkey)
{
echo $ttkey.'<br \>';
}
}
?>
I know I am making some blunder.. please correct me.
-
How can I log the time it was run?
And run it again when an hour is over.
A little more detail, code would help me.
-
I need to run a php file every one hour. Is there any other solution apart from cron job?
-
Thanks Guys...it worked. I will try include() too...
My first php class is test1.php
<?php
class MyFirstClass{
private $string1="Hello",$string2="Testing",$string3="Hi";
function getString1(){
return $this->string1;
}
function getString2(){
return $this->string2;
}
function getString3(){
return $this->string3;
}
}
?>
My second php class is test2.php
<?php
require('test1.php');
class MySecondClass{
private $var1,$var2,$var3;
public function __construct(MyFirstClass $firstClass){
$this->getFirstClassVars($firstClass);
$this->printFirstClassVars();
}
function getFirstClassVars($firstClass){
$this->var1 = $firstClass->getString1();
$this->var2 = $firstClass->getString2();
$this->var3 = $firstClass->getString3();
}
function printFirstClassVars(){
print $this->var1."<br/>";
print $this->var2."<br/>";
print $this->var3."<br/>";
}
}
$firstClass = new MyFirstClass();
$secondClass = new MySecondClass($firstClass);
?>
And this is what I needed. It worked.
-
Thanks Salate and all, it worked.
Now I need to separate this classes as two php, MyFirstClass.php and MySecondClass.php. Save them in the same folder and try.
If there is any other slight change I need to make. Please help.
-
Are you guys helping or confusing...
thanks though.. let me try
-
This is my code. I have three strings in MyFirstClass. I am trying to call them in MySecondClass
<?php
class MyFirstClass{
private $string1="Hello",$string2="He",$string3="Hi";
function getString1(){
return $this->string1;
}
function getString2(){
return $this->string2;
}
function getString3(){
return $this->string3;
}
}
class MySecondClass{
private $var1,$var2,$var3;
__Construct(MyFirstClass $firstClass){
getFirstClassVars($firstClass);
printFirstClassVars();
}
function getFirstClassVars($firstClass){
$this->var1 = $firstClass->getString1();
$this->var2 = $firstClass->getString2();
$this->var3 = $firstClass->getString3();
}
function printFirstClassVars(){
print $this->var1."<br/>";
print $this->var2."<br/>";
print $this->var3."<br/>";
}
}
$firstClass = new MyFirstClass();
$secondClass = new MySecondClass($firstClass);
?>
I am getting this error "syntax error, unexpected T_STRING, expecting T_FUNCTION" at this line __Construct(MyFirstClass $firstClass){
-
Where exactly I have to write this function?
Can I write this is any class or separate.
And how do I call it where I need it?
-
I have test1.php{
$string1;
$string2;
....
... //10 strings in this class
$string10;
}
Another class test2.php
{
.....
....
I want to use those 10 strings here, how should I do it?
}
-
ltrim is not working.
I also tried
{
....
$sentences = split('[.!?]',$para);
$sentences = ltrim($sentences,'\"');
i also tried
$bad = array("\xc2","\x80","\x8c","\x9d","\x98","\x99");
$find[] = '“'; // left side double smart quote
$find[] = 'â€'; // right side double smart quote
$find[] = '‘'; // left side single smart quote
$find[] = '’'; // right side single smart quote
$find[] = '…'; // elipsis
$find[] = '—'; // em dash
$find[] = '–'; // en dash
$replace[] = '"';
$replace[] = '"';
$replace[] = "'";
$replace[] = "'";
$replace[] = "...";
$replace[] = "-";
$replace[] = "-";
foreach ($sentences as $final)
{
str_replace($find,$replace,$final);
str_replace($bad,"",$final);
I TRIED EVERYTHING, BUT THE QUOTES DOESN'T SEEM TO BE GOING FROM MY SENTENCES FORMED...

If we give a big article for say. It will obviously have many sentences. I am splitting my article (paragraph) into sentences based on delimiters (.!?) By using the regular expression of MadTechie I am seeing only three sentences are formed in any large amount of paragraph I submit. I should get rest of the sentences till the paragraph finish right??
But the output is only 3 sentences using MadTechie's expression. Any solution??
-
Any help ????
-
I have a variable $result I want to use it outside my loop, how can I??
...
foreach ($sent as $result)
{
...
... //$result undergoes some calculation.
}
...
foreach ($result as $result2) I want to use $result again later in the code...
{
echo $result2;
}
It gives me Invalid argument supplied for foreach()...
-
I fixed it...
I had given wrong local variable earlier.
-
I am taking sentences through a form on page. Then checking some condition and trying to insert them in database. I have issues while inserting...
foreach ($sentences as $final) {
......
else {
if(strlen($final) <= 120){
echo $final.'.<br />';}
else
echo substr($final,0,120). '.<br />';
//Inserting of final(sentences) in database starts
$sent = mysql_real_escape_string($_POST ['$final']);
$error= "Error while inserting, either User present or other. Please check database";
$inserted= "sentences inserted";
$result = mysql_query("SELECT sent FROM sentences WHERE sent='{$final}' ");
if($result)
{
$num = mysql_num_rows( $result );
if ($num == 0) {
$querypost = mysql_query ("INSERT INTO sentences (sent) VALUES ('$final')");
echo $inserted;
}
else echo $error;
}
}
}
Please correct my logic error.
