Since you are using quotes where there should not be any since they are not part of the search string. Also in you replacement text you left out the space so it would be a replacement, not an append. Thirdly there is no g flag, so the replacement only happens once per line.

str_replace
STR_REPLACE(3) 1 STR_REPLACE(3)str_replace - Replace all occurrences of the search string with the replacement stringSYNOPSIS
mixed str_replace (mixed $search, mixed $replace, mixed $subject, [int &$count])
DESCRIPTION
This function returns a string or an array with all occurrences of $search in $subject replaced with the given $replace value.
If you don't need fancy replacing rules (like regular expressions), you should always use this function instead of preg_replace(3).
PARAMETERS
If $search and $replace are arrays, then str_replace(3) takes a value from each array and uses them to search and replace on $subject. If
$replace has fewer values than $search, then an empty string is used for the rest of replacement values. If $search is an array and
$replace is a string, then this replacement string is used for every value of $search. The converse would not make sense, though.
If $search or $replace are arrays, their elements are processed first to last.
o $search
- The value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.
o $replace
- The replacement value that replaces found $search values. An array may be used to designate multiple replacements.
o $subject
- The string or array being searched and replaced on, otherwise known as the haystack. If $subject is an array, then the search
and replace is performed with every entry of $subject, and the return value is an array as well.
o $count
- If passed, this will be set to the number of replacements performed.
RETURN VALUES
This function returns a string or an array with the replaced values.
EXAMPLES
Example #1
Basic str_replace(3) examples
<?php
// Provides: <body text='black'>
$bodytag = str_replace("%body%", "black", "<body text='%body%'>");
// Provides: Hll Wrld f PHP
$vowels = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$onlyconsonants = str_replace($vowels, "", "Hello World of PHP");
// Provides: You should eat pizza, beer, and ice cream every day
$phrase = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy = array("pizza", "beer", "ice cream");
$newphrase = str_replace($healthy, $yummy, $phrase);
// Provides: 2
$str = str_replace("ll", "", "good golly miss molly!", $count);
echo $count;
?>
Example #2
Examples of potential str_replace(3) gotchas
<?php
// Order of replacement
$str = "Line 1
Line 2
Line 3
Line 4
";
$order = array("
", "
", "
");
$replace = '<br />';
// Processes
's first so they aren't converted twice.
$newstr = str_replace($order, $replace, $str);
// Outputs F because A is replaced with B, then B is replaced with C, and so on...
// Finally E is replaced with F, because of left to right replacements.
$search = array('A', 'B', 'C', 'D', 'E');
$replace = array('B', 'C', 'D', 'E', 'F');
$subject = 'A';
echo str_replace($search, $replace, $subject);
// Outputs: apearpearle pear
// For the same reason mentioned above
$letters = array('a', 'p');
$fruit = array('apple', 'pear');
$text = 'a p';
$output = str_replace($letters, $fruit, $text);
echo $output;
?>
NOTES
Note
This function is binary-safe.
Caution
Replacement order gotcha
Because str_replace(3) replaces left to right, it might replace a previously inserted value when doing multiple replacements. See
also the examples in this document.
Note
This function is case-sensitive. Use str_ireplace(3) for case-insensitive replace.
