STR_REPLACE(3)								 1							    STR_REPLACE(3)

str_replace - Replace all occurrences of the search string with the replacement string

SYNOPSIS
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. SEE ALSO
