I have some code working with arrays that I wrote but forgot what the "&" does to an array. I know the results and it works but I can not remember nor can I seem to find it anywhere. Probably not using the right search term. If some one can remind me It would be greatly appreciated.

I just switch to a ubuntu server and it works so, it is not the code it is the operating system. Many Thanks to all of you

I tried the script from gizmola and still get the same results, no open of file. vinny42 /home/******/pubic_html is my root directory. Apache owns it as well as the txt file I am trying to open. So are you saying I should move the file to /home/*****/public_html? This is where my webfiles are.

I did not set home to 777. I did open home up for selinux. I have the program at a building stage so I know where I lose everything. All works well except for the opening of the file. It is for a small program that will take in orders add them up display all info and write to this flat file. Later, when I learn more, I will incorportate MySQL instead of this flat file. At present this will work for the fjist stages, that is if I can get it to open. Thanks for your time.

The path is correct. I had it the second way but in desperation thought if I put it closer to the tree stem it might help. I just took the error suppression and I got nothing from ifopen(). I am running LAMP on CentOS 6.4 I opened up home directories on selinux There is just some small thing I am not seeing.

I have been working on opening, writing to, and closing a text file. I have direct address to the file in my php. I have the directory and the text file world readable, writable, and excutionable, in short 777 in the whole path. I have also assigned the file name to apache:apache (user, group). I have tried my own machine name, no luck. Here is the code // open file for appending @ $fp = fopen("/home/orders/orders.txt", 'ab'); flock($fp, LOCK_EX); // LOCK THE FILE FOR WRITING if (!$fp) { echo "<p><strong> Your order could not be processed at this time. Please try again later.</strong></p></body></html>"; exit; } fwrite($fp, $outputstring, strlen($outputstring)); flock($fp, LOCK_UN); // RELEASE WRITE LOCK fclose($fp); echo "<p>Order written.</p>"; My if is a boolean if true I write to the file. False I get not processed at this time. can anyone see something wrong? Thanks for any help

Anybody heard of phpStorm? I am going to download it tomorrow night and try it. -
Parse error: syntax error, unexpected $end on line 71
larka06 replied to larka06's topic in PHP Coding Help
Sorry I was so thick I missed the whole point. No excuse just late and tired. I just changed the indentation and now it works. Many thank for both of you. I guess I needed the scolding to get my attention. As for Kicken being better I am sure he is. I am a real newbie trying to teach myself. -
Parse error: syntax error, unexpected $end on line 71
larka06 replied to larka06's topic in PHP Coding Help
I have no spaces after ether the beginning <<<END_TEXT or the botttom END_TEXT. I am sure that the problem is down in the lower part. as you can see I have marked the ones not recognized. -
To me the parse error suggests that there is a missing semi-colon or quotation something like that but I can not find a single case of not having matches. As for the regular Expressions I know nothing so I just copied out of the book. I have been over them several times and all seems right. I have comments where I know that the unreconition begins. Here is the parser statement then the code..... Parse error: syntax error, unexpected $end in sort_words_by_length.php on line 71. There is only 70 lines. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Sorting words in a block of text by length</title> <meta http-equiv="content-type" content="text/html;charset=utf-8" /> <meta name="generator" content="Geany 0.21" /> <link href="common.css" rel="stylesheet" type="text/css"/> </head> <body> <h1>Sorting words in a block of text by length</h1> <?php $myText = <<<END_TEXT But think not that this famous town has only harpooners, cannibals, and bumpkins to show her visitors.

Thank both of you. There is nothing above it but the opening <?php

I have this error but can not see what is wrong. The parser says: PHP Parse error: syntax error, unexpected T_SL in sort_words_by_length.php on line 40. What is T_SL? below is the line it objects to followed by the whole text. <?php Line 40 -- $myText = <<<END_TEXT But think not that this famous town has only harpooners, cannibals, and bumpkins to show her visitors. Not at all. Still New Bedford is a queer place. Had it not been for us whalemen, that tract of land would this day perhaps have been in as howling condition as the coast of Labrador. END_TEXT; I have reread on heredocs and can not find anything wrong.

The output below is what I get if I put the echo statement anywhere but in the while Loop. Just before the while Loop is entered both $i and $numLines have 5 for an answer. Therefore the while Loop runs once and only one line is Justified. I have tried to set $i to zero just before entering the loop still runs only once. I cannot get even one echo from inside the while Loop. <?php // The text to justify $myText = <<<END_TEXT But think not that this famous town has only harpooneers, cannibals, and bumpkins to show her visitors. Not at all. Still New Bedford is a queer place. Had it nt been for us whalemen, that tract of land would this day perhaps have been in howling condition as the coast of Labador. END_TEXT; $myText = str_replace("\r\n", "\n", $myText); $lineLength = 60; // desired line lenght $myTextJustified = " "; $numLines = substr_count($myText,"\n");$startOfLine = 0; echo $numLines; //Move through each line in turn for($i=0; $i < $numLines; $i++) $originalLineLength = strpos($myText, "\n", $startOfLine) - $startOfLine; $justifiedLine = substr($myText, $startOfLine, $originalLineLength); $justifiedLineLength = $originalLineLength; echo $numLines; echo $i // Keep adding spaces between words until the desired line length is reached while($i < $numLines -1 && $justifiedLineLength < $lineLength) { echo $i; for($j=0; $j< $justifiedLineLength; $j++){ if($justifiedLineLength < $lineLength && $justifiedLine[$j] == " ") { $justifiedLine =substr_replace( $justifiedLine, " ", $j, 0); $justifiedLineLength++; $j++; } } } // Add the justified line to the string and move to the start of the next line $myTextJustified .= "$justifiedLine\n"; $startOfLine += $originalLineLength + 1; ?> Here is the output.

Thanks for the advice on the php.ini file. I did as you say and will try it out now. As for me I am having more success now although, I was about to give up php. I like its' style alot like C.
-
Thanks to both of you for your time. I put the php tags around the ending brace and it worked! Suprised yes because I had just taken them off but must of done something else because it works.

I have two questions; One: I have looked at this code for two days and can not find why it will not run. Can someone tell me what is wrong? Two I think this wrox php is moving to fast for me as a newbie. Can anyone recommend a book that maybe starts out a little slower? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Fibonacci sequence</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8"/> <meta http-equiv="content-style-type" content="text/css"/> <link href="common.css" rel="stylesheet" type="text/css"/> <style type="text/css"> th{text-align:left; background-color: #999;} th, td{padding: 0.4em;} tr.alt td{background: #ddd;} </style> </head> <body> <h2>Fibonacci sequence</h2> <table cellspacing="0" border="0" style="width: 20em; border: 1px solid #666;"> <tr> <th>Sequence #</th> <th>Value</th> </tr> <tr> <td>F<sub>0</sub></td> <td>0</td> </tr> <tr class="alt"> <td>F<sub>1</sub></td> <td>1</td> </tr> <?php $iterations = 10; $num1 = 0; $num2 = 1; for($i=2; $i <= $iterations; $i++) { $sum = $num1 + $num2; $num1 = $num2; $num2 = $sum; ?> <tr<?php if($i % 2 != 0) echo 'class="alt"' ?>> <td>F<sub><?php echo $i?></sub></td> <td><?php echo $num2?></td> </tr> } </table> </body> </html> I am not sure I did that code thing right?

Thank you. I was sure it was something simple.

I have been studing php using a book named Wrox PHP. So far I have had alot of trouble getting the code to work. I have had to us work arounds to get the results I am suppose to get. Here is the code the way it is in the book: " <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Circle Properties</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8"/> <meta http-equiv="content-style-type" content="text/css"/> <link href="common.css" rel="stylesheet" type="text/css"/> </head> <body> <?php $radius = 4; $diameter = $radius * 2; $circumference = M_PI * $diameter; $area = M_PI * pow($radius, 2); echo "This circle has...<br />"; echo "A radius of " . $radius . "<br />"; echo "A diameter " . $diameter . "<br />"; echo "A circumference of " . $circumference . "<br />"; echo "An area of " . $area .

What is wrong? Should I abandon the book and get a better one some one knows about?
