Split a string array into pieces
Question by arkchong
let said I have an array that store like this.
Array (
[0] => width: 650px;border: 1px solid #000;
[1] => width: 100%;background: white;
[2] => width: 100%;background: black;
)
How should I make the array[0] string split into piece by separated the “;”? Then I want to save them in array again, or display them out. How should I do it?
Array(
[0] => width: 650px
[1] => border: 1px solid #000
)
Any idea? Thank in advanced

I would personally use the preg_split to get rid of that extra array element that would occur from the final semicolon…
$newarray = array();
foreach ($array as $i => $styles):
// Split the statement by any semicolons, no empty values in the array
$styles = preg_split("/;/", $styles, -1, PREG_SPLIT_NO_EMPTY);
// Add the semicolon back onto each part
foreach ($styles as $j => $style) $styles[$j] .= ";";
// Store those styles in a new array
$newarray[$i] = $styles;
endforeach;
Edit: Don’t add the semicolon to each line:
$newarray = array();
foreach ($array as $i => $styles):
// Split the statement by any semicolons, no empty values in the array
$newarray[$i] = preg_split("/;/", $styles, -1, PREG_SPLIT_NO_EMPTY);
endforeach;
Which should output:
Array(
[0] => width: 650px;
[1] => border: 1px solid #000;
)
Unlike explode, which should output:
Array(
[0] => width: 650px;
[1] => border: 1px solid #000;
[2] => ;
)

An example
foreach($array as $item) {
$mynewarray = explode(";",$item);
foreach($mynewarray as $newitem) {
$finalarray[] = $newitem.";";
}
//array is ready
}
