How to find strings and add these string to an array - php

Question

Anyone please help me..
$description = "This is product description. Quality is good. Title:title Price:1000 Size:XL, Medium, Small Color:red, green, blue. Any one can buy freely. ";
I wanna find "Title:", "Price:", "Size:" and "Color:" from that string and I want to add those values in an array.
My desired output is:
$new_desc = array(
'title'=>'title',
'price'=>1000,
'size'=>array(
[0]=>'XL',
[1]=>'Medium',
[2]=>'Small',
),
'color'=>array(
[0]=>'red',
[1]=>'green',
[2]=>'blue',
),
);
Thanks a lot!!!

Using preg_match_all, you can find you your identifiers (Price, Size ...) and their Values. You then just have to alter that to fit your array form.
Read up on preg_match_all and Regular Expressions.
<?php
$string = "This is product description. Quality is good. Title:title Price:1000 Size:XL, Medium, Small Color:red, green, blue. Any one can buy freely. ";
preg_match_all('/([^ ]{1,}):(([0-9a-z]{1,}|([0-9a-z,]{1,})( ))+)/i', $string, $matches);
var_dump($matches);
So this gives you:
array(6) {
[0]=>
array(4) {
[0]=>
string(11) "Title:title"
[1]=>
string(10) "Price:1000"
[2]=>
string(22) "Size:XL, Medium, Small"
[3]=>
string(22) "Color:red, green, blue"
}
[1]=>
array(4) {
[0]=>
string(5) "Title"
[1]=>
string(5) "Price"
[2]=>
string(4) "Size"
[3]=>
string(5) "Color"
}
[2]=>
array(4) {
[0]=>
string(5) "title"
[1]=>
string(4) "1000"
[2]=>
string(17) "XL, Medium, Small"
[3]=>
string(16) "red, green, blue"
}
[3]=>
array(4) {
[0]=>
string(5) "title"
[1]=>
string(4) "1000"
[2]=>
string(5) "Small"
[3]=>
string(4) "blue"
}
[4]=> [...]
}
if you iterate over the first set of matches from this array, you can create your desired output easily using stripos to find occurances of , and explode to generate arrays from your , seperated values.
$new_desc = array();
foreach ($matches[1] as $index => $identifier) {
$value = $matches[2][$index];
if(stripos($value, ',') !== FALSE) {
$value = explode(',',$value);
}
$new_desc[$identifier] = $value;
}
var_dump($new_desc);

Use preg_match_all() to extract the key value pairs first:
preg_match_all('/[A-Z][a-z]+:[a-z\d, ]+/', $description, $matches);
Then loop through the $matches array and use explode() to create your result array:
foreach ($matches[0] as $value) {
list($key, $qty) = explode(':', $value);
if (strpos($qty, ',') !== FALSE) {
$result[strtolower($key)] = array_map('trim', explode(',', $qty));
} else {
$result[strtolower($key)] = trim($qty);
}
}
var_dump($result);
Output:
array(3) {
["title"]=>
string(5) "title"
["price"]=>
string(4) "1000"
["color"]=>
array(3) {
[0]=>
string(3) "red"
[1]=>
string(5) "green"
[2]=>
string(4) "blue"
}
}
