STR_IREPLACE(3) 1 STR_IREPLACE(3)
str_ireplace - Case-insensitive version ofstr_replace(3).
SYNOPSIS
mixed str_ireplace (mixed $search, mixed $replace, mixed $subject, [int &$count])
DESCRIPTION
This function returns a string or an array with all occurrences of $search in $subject (ignoring case) replaced with the given $replace
value. If you don't need fancy replacing rules, you should generally use this function instead of preg_replace(3) with the i modifier.
PARAMETERS
If $search and $replace are arrays, then str_ireplace(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
Returns a string or an array of replacements.
EXAMPLES
Example #1
str_ireplace(3) example
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
NOTES
Note
This function is binary-safe.
Caution
Replacement order gotcha
Because str_ireplace(3) replaces left to right, it might replace a previously inserted value when doing multiple replacements.
Example #2 in the str_replace(3) documentation demonstrates how this may affect you in practice.
