str_replace between two numerical strings - php

Question

Another problem with str_replace, I would like to change the following $title data into URL by taking the $string between number in the beginning and after dash (-)
Chicago's Public Schools - $10.3M
New Jersey - $3M
Michigan: Public Health - $1M
The desire output is:
chicago-public-school
new-jersey
michigan-public-health
PHP code I am using
$title = ucwords(strtolower(strip_tags(str_replace("1: ", "", $title))));
$x = 1;
while ($x <= 10) {
$title = ucwords(strtolower(strip_tags(str_replace("$x: ", "", $title))));
$x++;
}
$link = preg_replace('/[<>()!#?:.$%\^&=+~`*é"\']/', '', $title);
$money = str_replace(" ", "-", $link);
$link = explode(" - ", $link);
$link = preg_replace(" (\(.*?\))", "", $link[0]);
$amount = preg_replace(" (\(.*?\))", "", $link[1]);
$code_entities_match = array(''s', '"', '!', '#', '#', '$', '%', '^', '&', '*', '(', ')', '+', '{', '}', '|', ':', '"', '<', '>', '?', '[', ']', '', ';', "'", ',', '.', '_', '/', '*', '+', '~', '`', '=', ' ', '---', '--', '--');
$code_entities_replace = array('', '-', '-', '', '', '', '-', '-', '', '', '', '', '', '', '', '-', '', '', '', '', '', '', '', '', '', '-', '', '-', '-', '', '', '', '', '', '-', '-', '-', '-');
$link = str_replace($code_entities_match, $code_entities_replace, $link);
$link = strtolower($link);
Unfortunately the result I got:
-chicagoamp9s-public-school
2-new-jersey
3-michigan-public-health
Anyone has a better solution for this? Thanks guys!
(the ' changed into amp9 - wonder why?)

Answer 1

If I understand you correctly:
if (preg_match('!\d+:\s+(.*)\s+-\s+\$\d+(?:\.\d+)?!', $title, $groups)) {
$words = strip_tags(strtolower($groups[1]));
$words = preg_replace('\[^\s\w]!', '', $words);
$words = preg_replace('!\s+!', '-', $words);
$words = preg_replace('!-+!', '-', $words);
echo $words;
}
One thing: your text has "1. Chicago's..." not "1: ..." like your code would seem to suggest. Is one an error or is there something else going on?

Answer 2

You can do:
$str = "1. Chicago's Public Schools - $10.3M";
$from = array('/^\d+\.\s+([^-]*) -.*$/','/[^A-Z ]/i','/\s+/');
$to = array("$1",'','-');
$str = strtolower(preg_replace($from,$to,$str));
echo $str; // prints chicagos-public-schools

Answer 3

<?php
$lines = array("1. Chicago's Public Schools - $10.3M",
"2. New Jersey - $3M",
"3. Michigan: Public Health - $1M"
);
// remove the number bullets
$lines = preg_replace('/\ - \$\d*\.?\d*M$/', '', $lines);
// remove the trailing dollar amount
$lines = preg_replace('/^\d+\.\ /', '', $lines);
// remove ignore chars
$ignore_pattern = "/['s|:]/";
$lines = preg_replace($ignore_pattern, '', $lines);
for ($i=0; $i<count($lines); $i++) {
$lines[$i] = implode('-',explode(' ', strtolower(trim($lines[$i]))));
}
print_r($lines);
and the output:
Array
(
[0] => chicago-public-school
[1] => new-jerey
[2] => michigan-public-health
)
EDIT Start:
<?php
$lines = array("1. Chicago's Public Schools - $10.3M",
"2. New Jersey - $3M",
"3. Michigan: Public Health - $1M",
"4. New York's Starbucks - $2M",
);
$lines = preg_replace('/\ - \$\d*\.?\d*M$/', '', $lines);
$lines = preg_replace('/^\d+\.\ /', '', $lines);
$ignore_strings = array("'s", ':');
for ($i=0; $i<count($lines); $i++) {
foreach ($ignore_strings as $s) {
$lines[$i] = str_replace($ignore_strings, '', $lines[$i]);
}
}
for ($i=0; $i<count($lines); $i++) {
$lines[$i] = implode('-',explode(' ', strtolower(trim($lines[$i]))));
}
print_r($lines);
output:
Array
(
[0] => chicago-public-schools
[1] => new-jersey
[2] => michigan-public-health
[3] => new-york-starbucks
)
Hope it meets your needs.
EDIT End.

Answer 4

Assuming you already have extracted titles correctly like "Chicago's Public Schools", then to generate pagenames out of them:
function generatePagename($s) {
//to lower
$pagename = trim(html_entity_decode(strtolower($s), ENT_QUOTES));
//remove 's
$pagename = trim(preg_replace("/(\'s)/", "", $pagename));
//replace special chars with spaces
$pagename = trim(preg_replace("/[^a-z0-9\s]/", " ", $pagename));
//replace spaces with dashes
$pagename = trim(preg_replace("/\s+/", "-", $pagename));
return $pagename;
}
Which will convert something like
Chicago's "Public": Scho-ols1+23
to
chicago-public-scho-ols1-23.

Answer 5

Finally I looked back to initial code and have some fixes:
$title = ucwords(strtolower(strip_tags(str_replace("1. ","",$title))));
$x=1;
while($x <= 10) {
$title = ucwords(strtolower(strip_tags(str_replace("$x. ","",$title))));
$x++;
}
$data = preg_replace('/[<>()!#?:.$%\^&=+~`*&#;"\']/', '',$title);
$urldata = str_replace(" ","-",$data);
$data = explode(" - ",$data);
$link = preg_replace(" (\(.*?\))", "", $data[0]);
$budget = preg_replace(" (\(.*?\))", "", $data[1]);
$code_entities_match = array( '"' ,'!' ,'#' ,'#' ,'$' ,'%' ,'^' ,'&' ,'*' ,'(' ,')' ,'+' ,'{' ,'}' ,'|' ,':' ,'"' ,'<' ,'>' ,'?' ,'[' ,']' ,'' ,';' ,"'" ,',' ,'.' ,'_' ,'/' ,'*' ,'+' ,'~' ,'`' ,'=' ,' ' ,'---' ,'--','--');
$code_entities_replace = array('' ,'-' ,'-' ,'' ,'' ,'' ,'-' ,'-' ,'' ,'' ,'' ,'' ,'' ,'' ,'' ,'-' ,'' ,'' ,'' ,'' ,'' ,'' ,'' ,'' ,'' ,'-' ,'' ,'-' ,'-' ,'' ,'' ,'' ,'' ,'' ,'-' ,'-' ,'-','-');
$link = str_replace($code_entities_match, $code_entities_replace, $link);
$link = strip_tags(str_replace("amp39s","",$link));
$link = strtolower($link);
What a mess, I know, but it works anyway, thanks guys for helping me, especially cletus who found the mistake between 1. and 1:
