PHP or PHP: Hypertext Preprocessor is a general-purpose server-side scripting language originally designed for Web development to produce dynamic Web pages. It is one of the first developed server-side scripting languages to be embedded into an HTML source document, rather than calling an external file to process data. (wiki)

Even though PHP is much younger than other languages, it was established as the leading website programming language.

What do PHP code look like?

It is a rather simple language and most of its syntax is borrowed from C except for dealing with the types

PHP array to string. Sometimes data arrive in array which has to be convert into string, in this situation we can use implode() function which is used to convert the array into string.

One-Dimensional Arrays to String
Use the implode() function:

$array = array(‘lastname’, ‘email’, ‘phone’);
$comma_separated = implode(",", $array);

Or the var_export function:

return var_export($arr);

Multi-Dimensional Arrays to String

This code:

return implode(‘,’, $arr);

Results in this:

8 Array to string conversion
8 Array to string conversion
8 Array to string conversion
Array,Array,Array

Use this function:

$arr = array (…your array…);
foreach($arr AS $i => $v)
{
$arrSize = sizeOf($arr[$i]);
if ($arrSize > 0)
{
$str .= ‘<strong>’ . ucfirst($i) . ‘:</strong&gt

TortoiseSVN Turn of Merge. Here is a trick for TortoiseSVN:

How to turn off “auto-merge” in Subversion is to set SVN external diff tool to a program that will constantly fail. If external diff program fails, SVN concludes that conflict is unresolvable and wouldn’t merge it.

svn –diff-cmd=/bin/false

A good choice for the new mime-type would be:

application/octet-stream

Which just means a general binary type file.

To set the Subversion tag of a file using TortoiseSVN:

1. Right-click on the file and select properties,
2. Select the Subversion tab and enter the tag.

This picture illustrates the last part:

A simple code to make every first character uppercase in a string, even they are separated by hyphen.

ucwords

string ucwords ( string $str )

Returns a string with the first character of each word in str capitalized, if that character is alphabetic.

Examples:
ucwords()

<?php
$foo = ‘the quick brown fox’;
$foo = ucwords($foo); // The Quick Brown Fox

$bar = ‘THE QUICK BROWN FOX’;
$bar = ucwords($bar); // THE QUICK BROWN FOX
$bar = ucwords(strtolower($bar)); // The Quick Brown Fox
?>

There comes a time that you need to rename a table in MySQL. You either run an SQL query to do this or do it with phpMyAdmin if you don’t want to bother remembering the SQL to do so.

RENAME TABLE tbl_name TO new_tbl_name
[, tbl_name2 TO new_tbl_name2] …

This statement renames one or more tables.

Example:
The example SQL below renames the MySQL table tablename to tablename_renamed:

RENAME TABLE tablename TO tablename_renamed

Renaming a MySQL table with phpMyAdmin:
Select the database then table, and click the “Operations” tab. Then

Form validation working on the input form in the front-end, but not working in the backend. Either doesn’t work or the form submits when it is not meant to.

You might have to change the toolbar buttons…

Put something like this above your code:

$html=’<a class="toolbar" class="button validate" type="submit" onclick="javascript: return myValidate(adminForm);" href="#">
<span title="Apply" class="icon-32-apply"></span>Apply</a>’;

JToolBarHelper::title(JTEXT::_(‘Edit Placement List’),’sections.png’);
$bar = & JToolBar::getInstance(‘toolbar’);
$bar->appendButton( ‘Custom’, $html);

Or.. instead of usual script, replace it with the script:

<script language="javascript" type="text/javascript">
<!–
function submitbutton(pressbutton) {
var form = document.adminForm;
if (pressbutton == ‘cancelemployer’) {
document.adminForm.task.value = pressbutton;
form.submit()
