PHP - Code To Find String Within A Field

I have the following variable:

$text = "javascript:openimage('http://images.icecat.biz/img/norm/high/5966342-254.jpg',850,850)"

Now I want to put the string "http://images.icecat.biz/img/norm/high/5966342-254.jpg" into a variable called $url
( $url = "http://images.icecat.biz/img/norm/high/5966342-254.jpg" )

How do I do this?

I am making a online Bible with search function. I was able to do the boolean search for text keywords without much trouble. Now I want a user to be able to type in an exact verse into search form and have that verse display in results.

IE: User types in John 3:16 and search result displays that verse. The following works if the user types John:3:16. I cannot figure out how to do this without requiring the user to type a : after book name.
Code: [Select]
if($search_type=='verse'){

$query2 = explode(":", $query);
$bookquery = $query2[0];
$chapterquery = $query2[1];
$versequery = $query2[2];

$result4 = $db->sql_query("select * FROM Bible$version WHERE book = '$bookquery' AND chapter= '$chapterquery' AND verse ='$versequery'");
while ($row = $db->sql_fetchrow($result4)) {
$book = $row['book'];
$chapter = $row['chapter'];
$verse = $row['verse'];
$scripture = $row['scripture'];

echo "<b><a href=\"modules.php?name=Bible&amp;call=chapter&amp;viewbook=$book&amp;viewchapter=$chapter&amp;version=$version\">$book</a>&nbsp;$chapter:$verse</b>";
echo "<br>";
echo "$scripture";
echo "<hr>";
}

if(!$query){
echo "<b>You did NOT enter any keywords.</b><br>";
}
if(!$scripture){
echo "<b>No results found.</b>";
}

}

}

Is there a function to find first integer in the string and insert a : before it?

Is there an easy way to find a numeric value in a string if I don't know what the string will contain?
For example I want '52' out of: mystring52

Hopefully there is already a simple function to do this? I'm thinking there may not be as the string having more than one group of numbers may confuse matters. I'm just dealing with abcdef123 or similar in this case though.

How can I check this string to see if it has a ~ character using php?

Code: [Select]
$string = 'userlocation~credentials~specialties';

Is it pasible to find all occurrences of strings "North" and "North-East" in some txt file and save number of occurrences in some variables??

Hello everyone,

I am trying to select and return any rows that have a specific string in it.
Let's say I have a column name "item_id" and in every row of that column I have values like so:

row A: (11,22,44,34)
row B: (12,56,78,98)

If the user picks the number '22', I use the following SQL line to get the row in which the number '22' is contained.

SELECT * FROM Persons WHERE City LIKE '%22%'
and row A gets returned, just like it is suppose to.

The problem is, if the user selects a single digit number like '2', both row A and row B gets returned because they both have values that contain the number '2' in it.
Instance, row A has the number '22' and row B has the number '12' so both rows get returned when the number '2' is requested. I don't want that, I only want the row that has the exact number '2' or '34' or whatever number I request, to be returned.

So to get around this problem, I am wrapping my numbers in letters like so:

row A: (a11a,a22a,a44a,a34a)
row B: (a12a,a56a,a78a,a98a,a2a)

and requesting it like so:

SELECT * FROM Persons WHERE City LIKE '%a22a%'
My question is: Is there a better way to work out this logic?

Hi All,

I'm new at php and I need your help.

I'm trying to find a string in a website. I want my website to get a string on another website(I have full access) without really opening it on a browser. For example the string is "MyID=123456", i want to find "MyID=123456"(the MyID number is random and always changing but always 6 random numbers) on another website and output only "123456" on my website. Is this possible?

Please help. Thanks

Hello,

I have a few strings that contain dates along with some other text.
The string looks like this:

Code: [Select]
Hi, could you please add these dates to the database?<br />
 <br />
<br />
2-September-2011<br />
6-September-2011<br />
7-September-2011<br />
8-September-2011<br />
9-September-2011<br />
 <br />
Thank you.

Dates are always the same format. Sometimes there's a single date, most times there are multiple.
Does anyone know how can I get the dates from this string to add them to my sql database?

Thank you!

I wanted to replace a strings in a large text file .. what would be the fastest way ?!

e.g the text file contains ..

INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here');

I wanted to replace the string " VALUES (1, " with  "VALUES (" in each line ..
I'm new in PHP so any response would be much appreciated .. thanks

Hi there!
I am wondering if anyone knows how to handle strings that contain form fields, so when the form is submitted the fields inside the string are updated.

For example say i have the following $string:
Code: [Select]
please enter your username: <input type=text size=50 name=username value=" ">
When I display it on the browser, inside of a form, it displays the blank text field.
Say the user enters a value in the text field, "John", and hits submit.

I need the $string to be updated to the following:
Code: [Select]
please enter your user name: <input type=text size=50 value="John">
I know it sounds wierd but I need the form to be inside of the string!

Thanks in advance for any help!

Hey all,
Basically I have this code which technically should work, but I have put an error in the logic somewhere and am really struggling to find it, I've been going over it for about an hour now :/

The error is that in the second part (// Enter them into the activities database if they're not already there), it won't enter them, and it won't show the word 'Randomevent1' either, so clearly somehow I have put in something to prevent it performing that step.

Can anybody help me out? I'd be amazingly grateful, I have no clue how I've screwed it up.

if(isset($_POST['submit'])){

$ownerid = $_SESSION['id'];

// If completed = Y give an error
$completeyn = "SELECT completed FROM activities WHERE playerno='$ownerid' AND activityno = '1'";
$completecheck=mysql_query($completeyn) or die(mysql_error());
while($row = mysql_fetch_array( $completecheck )) {
if($row['completed'] == 'Y'){ echo 'Oops, you\'ve already done this twice today!';} else {

// Enter them into the activities database if they're not already there
$stepno2 = "SELECT playerno, timesdone FROM activities WHERE playerno='$ownerid' AND activityno = '1'";
$stepnoanswer2=mysql_query($stepno2) or die(mysql_error());
$num_rows2 = mysql_num_rows($stepnoanswer2);
echo $num_rows2;
if($num_rows2 == '0'){ $putintodb2 = mysql_query("INSERT INTO activities (playerno, activityno, timesdone) VALUES ('$ownerid', '1', '1')") or die("Error: ".mysql_error());
echo 'Randomevent1';
 }else{

// If they are already there update their stepcount
$updatestepcount2=("UPDATE activities SET timesdone=timesdone+'1' WHERE playerno='$ownerid' AND activityno = '1'");
$newstepcount2=mysql_query($updatestepcount2);
echo 'Randomevent2';}

// If this new stepcount is equal to 2, set completed to Y
$checkstep = "SELECT timesdone FROM activities WHERE playerno='$ownerid' AND activityno = '1'";
$checkstepresult=mysql_query($checkstep) or die(mysql_error());
while($row = mysql_fetch_array( $checkstepresult )) {
if($row['timesdone'] == '2'){
echo $row['timesdone'];
$updatestepcount22=("UPDATE activities SET completed = 'Y' WHERE playerno='$ownerid' AND activityno = '1'");
$newstepcount22=mysql_query($updatestepcount22);
 }


}}}}

Here's a neat little script that you simply use by calling yourscript.php?microsoft (where microsoft is any keyword you want) and it returns 100 related keywords.  It's pretty raw in it's form.  I didn't write it. 
Purely for learning, I'm trying to figure out how to
1) issue a line break between each item in the elements of the arry? 
2) return only the keywords and not the associated array info. 

Currently, it returns results like:
Array ( => microsoft [1] => microsoft security essentials [2] => microsoft office [3] => microsoft templates [4] => microsoft updates [5] => microsoft silverlight [6] => microsoft word [7] => microsoft money [8] => microsoft office 2010 [9] => microsoft clip art [10] => microsoft [11] => microsoft security essentials [12] => microsoft office [13] => microsoft templates [14] => microsoft updates [15] => microsoft silverlight [16] => microsoft word [17] => microsoft money [18] => microsoft office 2010 [19] => microsoft clip art [20] => microsoft security essentials [21] => microsoft security essentials review [22] => microsoft security essentials alert [23] => microsoft security essentials update [24] => microsoft security essentials 2.0

I'm wanting to know how to make it return results like...
microsoft
microsoft security essential
microsoft office
microsoft templates
etc....
