Code of the cleanLongWords() function
Use of the cleanLongWords() subroutine to make a code with a set of alphanumeric characters are used for different purposes as required. The maximum word length judged is one which has a random generation of characters and words chosen in making of the set of characters or code resultantly.
function cleanLongWords($text, $nrchr=2, $maxword=23) {
// function to clean text with multiple consecutive characters and very long words ( http://coursesweb.net/ )
// $nrchr = allowed number of consecutive character
// $maxword = maximum word length
$paterns = array();
$chr = array('q','w','e','r','t','y','u','i','o','p','a','s','d','f','g','h','j','k','l',';','z','x','c','v','b','n','m',',','!','@','#','%','&','_','=',':','"','`','~',';','â','á','é','í','ó','ú','ý','ø','č','ć','đ','š','ž','ā','ä','ǟ','ḑ','ē','ī','ļ','ņ','ō','ȯ','ȱ','õ','ȭ','ŗ','š','ț','ū','ž','ş','î','ă',"'",'$','\^','\*','\(','\)','\{','\}','\|','\?','\.','\[','\]','\/','\\\\','\>','\<');
// uncomment next line if you want to clean consecutive numbers too
/// $chr = array_merge($chr, array('1','2','3','4','5','6','7','8','9','0'));
$n_chr = count($chr);
for($i=0; $i<$n_chr; $i++) {$paterns[$i] = '/(['. $chr[$i] .']{'. $nrchr .',}){2,}/i'; }
$text = preg_replace($paterns, '$1', $text);
// if $maxword > 0, split the word to specified number of characters
return ($maxword > 0) ? wordwrap($text, $maxword, ' ', true) : $text;
}
<?php

PHP Coding and Methodology
Interpret, Parse, Replace variables in string using valuePhp-mysql CourseHome, HTML, CSS, JavaScript. You can replace variables in string using values defined in php development arpatech and you can also use the strtr() or preg_replace_callback() function. Make sure there is a particular pattern you are aware of and you are interested in making a choice of which course you are to take and the one that suits you. The code snippet provided below does just that.
Example with strtr():
<?php
// array with data for the variables added in string
$data = array(
'{$site}'=>'http://coursesweb.net/',
'{$year}'=>date('Y')
);
$str = 'Code-snippets from {$site} , added in: {$year}.';
$str2 = strtr($str, $data);
echo $str2; // Code-snippets from http://coursesweb.net/ , added in: 2014.
Example with preg_replace_callback()
- Click to select it.
<?php
// array with data for the variables added in string
$data = array(
'id'=>'test2',
'domain'=>'CoursesWeb.net'
);
$str = '<div id="{$id}">Parse this string, interpret {$domain} </div>';
$str2 = preg_replace_callback('/{\$([^}]+)}/', function($m) {
GLOBAL $data;
return $data[$m[1]];
}, $str);
echo $str2; // <div id="test2">Parse this string, interpret CoursesWeb.net </div>
PHP Code and Purpose
Force Download files using PHPPhp-mysql CourseHome, HTML, CSS, and JavaScript. The downloadFile() function given in the page are usable and a forced download of various type of files are made using primarily PHP in: csv, doc, html, jpg, pdf, png, ppt, xls, xml, zip, etc.
The downloadFile() function
// function to download files with php ( http://coursesweb.net/php-mysql/ )
// receives the path and filename to download
function downloadFile($file) {
$ar_ext = explode('.', $file);
$ext = strtolower(end($ar_ext));
$extensions = array(

echo "<h1>Error 404: File Not Found: <br /><em>$file</em></h1>";
}
}
<?php
// HERE ADD THE downloadFile() function
