What potential issues can arise when using str_replace() to replace specific strings in a larger string?

One potential issue that can arise when using str_replace() is that it replaces all occurrences of the specified string in the larger string, which may not be the desired behavior. To solve this, you can use the third parameter of str_replace() to limit the number of replacements made. 

// Example of using str_replace() with limit parameter to replace only the first occurrence
$original_string = "The quick brown fox jumps over the lazy dog";
$replacement_string = "cat";
$modified_string = str_replace("fox", $replacement_string, $original_string, 1);

echo $modified_string;
