PHP在foreach循环中替换多个字符串

Question

I'm grabbing the source of a page with a lot of PDF links (files) listed in a column like so. simple_php_dom.php

TALB20170826D-$A$$-RA11.pdf
TAP$20170826D-$A$$-RA11.pdf
TASD20170826D-$A$$-RA11.pdf
TAUA20170826D-$A$$-RA11.pdf
TAUB20170826D-$A$$-RA11.pdf
TAUC20170826D-$A$$-RA11.pdf
TAUD20170826D-$A$$-RA11.pdf
TBTP20170826D-$A$$-RA11.pdf
TCBY20170826D-$A$$-RA11.pdf

I need to rename them within the foreach loop

foreach($html->find('a') as $element) 
echo $element->href;

For instance TALB is an abbreviation for ALBANY, TAP is an abbreviation for Asia Pacific and so on.

I have a list of the names that correspond with the abbreviations but unsure how to rename them within the loop? Any help would be greatly appreciated!

You can put the list of replacements in arrays:

<?php    
/*
$list = [];   
$list[] = "TALB20170826D-\$A$$-RA11.pdf";
$list[] = "TAP$20170826D-\$A$$-RA11.pdf";
$list[] = "TASD20170826D-\$A$$-RA11.pdf";
$list[] = "TAUA20170826D-\$A$$-RA11.pdf";
$list[] = "TAUB20170826D-\$A$$-RA11.pdf";
$list[] = "TAUC20170826D-\$A$$-RA11.pdf";
$list[] = "TAUD20170826D-\$A$$-RA11.pdf";
$list[] = "TBTP20170826D-\$A$$-RA11.pdf";
$list[] = "TCBY20170826D-\$A$$-RA11.pdf";
*/
$list = $html->find('a');
$abbr = [
    "TALB",
    "TAP",
    // ...
];
$replacements = [
    "ALBANY",
    "Asia Pacific",
    // ...
];
foreach ($list as &$el) {
    $el->href = str_replace($abbr, $replacements, $el->href);
}

Demo

Or, to keep them all in one associative array (order doesn't matter and missing items just won't be replaced, no errors):

<?php    
/*$list = [];   
$list[] = "TALB20170826D-\$A$$-RA11.pdf";
$list[] = "TAP$20170826D-\$A$$-RA11.pdf";
$list[] = "TASD20170826D-\$A$$-RA11.pdf";
$list[] = "TAUA20170826D-\$A$$-RA11.pdf";
$list[] = "TAUB20170826D-\$A$$-RA11.pdf";
$list[] = "TAUC20170826D-\$A$$-RA11.pdf";
$list[] = "TAUD20170826D-\$A$$-RA11.pdf";
$list[] = "TBTP20170826D-\$A$$-RA11.pdf";
$list[] = "TCBY20170826D-\$A$$-RA11.pdf";*/
$list = $html->find('a');
$abbr = [
    "TALB" => "ALBANY",
    "TAP" => "Asia Pacific",
];
foreach ($list as &$el) {
    $el->href = strtr($el->href, $abbr);
}

Demo

Or use array_map(), maybe you'll find it a bit cleaner:

$list = array_map(function($el) use($abbr) {
    return strtr($el, $abbr);
}, $list);
