function not printing
I don't know if I missed something. The function is not printing at all.
PHP Code:
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
print_r($tdInnerHTML[1]);//prints all TD contents
/********************************************************************************/
function recValues(){
$tdValues = array();
$tdValues = "";
for($j = 0; $j < $totaltds; $j++){
if($j % 10 != 0){
$tdValues .= "'".$tdInnerHTML[1][$j];
if($j < 9){
$tdValues .= "', ";
}else{
$tdValues .= "'";
}
}
}
return $tdValues;
}
echo "<span style='font-weight: bold;'>hi".recValues()."hi</span><br />\n";

PHP will exit a function as soon as it reaches a return statement. Therefore, any code you place after the "return" will never be executed. Put the echo statement before the return, and you'll be okay.

I decided to rework the function from scratch. THis is what I came up with:
PHP Code:
function recValues(){
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
$line = 0;
$strLine = array();
for($k=0; $k < $totaltds; $k++){
if($k % 10 == 0){
print("line ");
$strLine[$line] =
}
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("'");
print("<span style='font-weight: bold; color: red'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("'<br />\n");
}else{
print("', ");
}
//return $tdValues[$j];
$j++;
$line++;
}
}
But I'm stuck. I need $strLine[$line] = to be equal to all this:
PHP Code:
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("'");
print("<span style='font-weight: bold; color: red'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("'<br />\n");
}else{
print("', ");
}

I hope I'm understanding this correctly. I'm assuming that you are saying that you want to store the entire "if" statement you mentioned in your second code block into a string variable. Is that correct?
If so, here is all you need to do:
PHP Code:
function recValues(){
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
$line = 0;
$strLine = array();
for($k=0; $k < $totaltds; $k++){
if($k % 10 == 0){
print("line ");
$strLine[$line] = '
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("\'");
print("<span style=\'font-weight: bold; color: red\'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("\'<br />\n");
}else{
print("\', ");
}';
}
//return $tdValues[$j];
$j++;
$line++;
}
}

}
//return $tdValues[$j];
$j++;
$line++;
}
}

Why isn't it printing? |

I see what's going on.
PHP Code:
function recValues(){
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
$line = 0;
$strLine = array();
for($k=0; $k < $totaltds; $k++){
if($k % 10 == 0){
print("line ");
$strLine[$line] = '
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("\'");
print("<span style=\'font-weight: bold; color: red\'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("\'<br />\n");
}else{
print("\', ");
}';
}
print($strLine[$line]);
//return $tdValues[$j];
$j++;
$line++;
}
}
print($strLine[$line]); is printing the code on the page. But I need the result of the code inside the single quotes. |

How about making $strLine[$line] equal to a function which would have:
PHP Code:
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("'");
print("<span style='font-weight: bold; color: red'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("'<br />\n");
}else{
print("', ");
}
How does that work? |

Gil - I don't think I can really help you much more unless I understand what it is you're ultimately trying to do.
The way your code is written, it's not really going to do anything at all. Unfortunately, I don't really understand what the goal is, so I can't begin to try to rewrite it to make it work for you.
Can you give me a short description of what it is you ultimately are trying to do?

What happened was that I accidentally erased my db table. Fortunately I had a copy of the table in HTML. So I'm trying to reconvert it to a db table.
Another problem was that I don't know how to upload a db table to an online server and connect to it. But I know how to connect to a created db on the online server. So I need this technique in both cases. I'm almost done with this.
I need $strLine[$line] to equal to a function which would have:
PHP Code:
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
print("'");
print("<span style='font-weight: bold; color: red'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
print("'<br />\n");
}else{
print("', ");
}
I came across something close to what I wanted:
PHP: create_function - Manual
The example:
PHP Code:
<?php
$newfunc = create_function('$a,$b', 'return "ln($a) + ln($b) = " . log($a * $b);');
echo "New anonymous function: $newfunc\n";
echo $newfunc(2, M_E) . "\n";
// outputs
// New anonymous function: lambda_1
// ln(2) + ln(2.718281828459) = 1.6931471805599
?>
Is that all that you need to know? Or you want me to explain further?

I almost succeeded into building my sql statement. But here is the result:
Quote:
line
0 INSERT INTO bible (book, book_spoke, recordType, book_title, chapter, chapter_spoke, verse, verse_spoke, text_data) VALUES ()
'1',
'1', '1',
'1', '1', 'gn',

'1', '1', 'gn', 'Genesis', '1',

9 INSERT INTO bible (book, book_spoke, recordType, book_title, chapter, chapter_spoke, verse, verse_spoke, text_data) VALUES ('1', '1', 'gn', 'Genesis', '1', '1', '1', '1', 'In the beginning God created the heaven and the earth.')

'3',
'3', 'And God said, Let there be light: and there was light.'

As you see there is a repetition. Instead it should be:
Quote:
line
9 INSERT INTO bible (book, book_spoke, recordType, book_title, chapter, chapter_spoke, verse, verse_spoke, text_data) VALUES ('1', '1', 'gn', 'Genesis', '1', '1', '1', '1', 'In the beginning God created the heaven and the earth.')
line
27 INSERT INTO bible (book, book_spoke, recordType, book_title, chapter, chapter_spoke, verse, verse_spoke, text_data) VALUES ('1', '1', 'gn', 'Genesis', '1', '1', '1', '1', 'And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.')
line
36 INSERT INTO bible (book, book_spoke, recordType, book_title, chapter, chapter_spoke, verse, verse_spoke, text_data) VALUES ('1', '1', 'gn', 'Genesis', '1', '1', '3', '3',
'And God said, Let there be light: and there was light.')
|
PHP Code:
function recValues(){
$contents_of_page = file_get_contents('../bible1.html');
preg_match_all("#<td.*>(.+)</td#Ui", $contents_of_page, $tdInnerHTML);
$totaltds = count($tdInnerHTML[1]);
$line = 0;
$strLine = array();
for($k=0; $k < $totaltds; $k++){
if($k % 10 == 0){
print("line ");
$strLine[$line] = "";
}
if($k % 10 != 0){
$j = 0;
$tdValues = array();
$tdValues[$j] = $tdInnerHTML[1][$k];
$strLine[$line] .= "'";
//print("'");
$strLine[$line] .= $tdValues[$j];
//print("<span style='font-weight: bold; color: red'>".$tdValues[$j]."</span>");
//print($tdInnerHTML[1][$k]);
if($k % 10 == 9){
$strLine[$line] .= "'";
//print("'<br />\n");
}else{
$strLine[$line] .= "', ";
//print("', ");
}
}
print($strLine[$line]."<br />\n");
//return $strLine[$line];
$j++;
if($k % 9 == 0){
$sql = "INSERT INTO bible (".fields().") VALUES (".$strLine[$line].")";
print("<span style='color: red;'>".$k." ".$sql."</span><br />\n");
$line++;
}
}
}

Gil - That's just because you're performing the following action every time the loop runs through a cycle:
PHP Code:
print($strLine[$line]."<br />\n");
The print statement you have after setting the $sql variable each time is plenty.
In order to avoid the first empty statement, I would recommend changing this statement:
PHP Code:
if($k % 9 == 0){
to
PHP Code:
if($k % 9 == 0 && !empty($k)){
